Typescript Web ComponentsTypescript Web ComponentsTypescript support comes with the next version of Smart Web Components. We are super excited about this. We will expose Interfaces, Types and Classes for all our stuff. Each API member will include descriptions, which will help you to use our product and see the intellisense suggestions by Visual Studio Code, Visual Studio and other IDEs with such support. Grid Typescript InitThis sample shows how to create basic Grid using TypeScript import {Grid, GridColumn, DataAdapter, Smart} from "../typescript/smart.elements";
window.onload = function () {
const grid: Grid = <Grid>document.createElement("smart-grid");
grid.columns = <GridColumn[]>[
{label: "First Name", dataField: "firstName"},
{label: "Last Name", dataField: "lastName"}
]
const adapter = new Smart.DataAdapter( {
dataSource: [
{firstName: "Name", lastName: "Last Name"},
{firstName: "Name 2", lastName: "Last Name 2"},
{firstName: "Name 3", lastName: "Last Name 3"},
{firstName: "Name 4", lastName: "Last Name 4"},
{firstName: "Name 5", lastName: "Last Name 5"}
],
dataFields: [
'firstName: string',
'lastName: string'

The new Microsoft Edge provides best in class compatibility with extensions and web sites, with great support for the latest rendering capabilities, modern web applications, and powerful developer tools across all supported platforms. Faster and clean-lookingOne of the first things you’ll notice about the new Edge is just how it looks, and how fast web sites load in it. Even when using 15 or more tabs, we didn’t find it slow down.What's important for your development with Smart Web ComponentsWe were regularly testing all releases of the new Edge with our product so on our end there are no surprises.The first important thing that we will point out is that Smart Web Components are fully compatible with the new Microsoft Edge browser. The second thing is that you will no longer need to include the webcomponents.js polyfill with Edge. More information about the Web Components support table: https://caniuse.com/#search=web%20components Posted in: HTML Elements, Javascript Tagged: edge, edge web browser, microsoft chromium edge, microsoft edge, web components Leave a comment Blazor and Web Components The Blazor framework enables you to build flexible and fast web applications with C# instead of JavaScript. The framework uses WebAssembly-based .NET runtime (client-side Blazor) and server-side ASP.NET Core (server-side Blazor). A Blazor app can invoke JavaScript functions from .NET and .NET methods from JavaScript code. To call into JavaScript from .NET, use the IJSRuntime abstraction. The InvokeAsync As it is possible to use Javascript with Blazor, it is easy to use Web Components with Blazor, too. The following tutorial will show you how to add our Grid Web Component and data bind it to a WeatherForecast web service within a Blazor web application: https://www.htmlelements.com/docs/blazor/ After following the steps in the tutorial you will have the following output:  Smart HTML Elements v5.1.0Smart HTML Elements v5.1.0 Release, Dec-03-2019What's New:
What's Improved:
Constructable Stylesheets Constructable Stylesheets make it possible to create stylesheets imperatively by invoking the CSSStyleSheet() constructor. The CSSStyleSheet object has two new methods that make it safer to add and update stylesheet. These methods are replace and replaceSync. replace() returns a Promise that resolves once any external references (@imports) are loaded, whereas replaceSync() doesn’t allow external references at all. Shadow DOM and Constructed StyleSheetsConstructable StyleSheets are very useful, when we use Shadow DOM. There is a new property called adoptedStyleSheets, which is available on Shadow Roots and Documents. This allows us to apply the styles defined by a CSSStyleSheet to a given DOM subtree. To do so, we set the property to an array of one or more stylesheets to apply to that element.Example:
// Create our shared stylesheet:
const sheet = new CSSStyleSheet();
sheet.replaceSync('a { color: red; }');
// Apply the stylesheet to a document:
document.adoptedStyleSheets = [sheet];
// Apply the stylesheet to a Shadow Root:
const node = document.createElement('div');
const shadow = node.attachShadow({ mode: 'open' });
shadow.adoptedStyleSheets = [sheet];
With Constructable StyleSheets, web application developers now have an explicit solution for creating CSS StyleSheets and applying them to Shadow DOM trees. The source code below, shows how to import a 'styles.css' file into the Grid's ShadowDOM.
const sheet = new CSSStyleSheet();
// replace all styles, allowing external resources:
sheet.replace('@import url("styles.css")')
.then(sheet => {
console.log('Styles loaded successfully');
})
.catch(err => {
console.error('Failed to load:', err);
});
grid.shadowRoot.adoptedStyleSheets = [sheet];
Material Dashboard and Premium Material Dashboard We are announcing two new Dashboard Templates, which will come as part of the Commercial subscription. Material Dashboard ProMaterial Dashboard is a Material Admin Dashboard with a design inspired by Google's Material Design. We are very excited to introduce it as we demonstrate how our web components play well with the material concepts. Material Dashboard was built over the latest version of Smart Web Components framework. Material Dashboard Premium Dashboard ProSave development time with this template with bright and fresh colors. It features a huge number of smart web components that can help you create amazing web apps. Premium Dashboard Web Components Theme BuilderTheme BuilderWe are excited to announce that the Theme Builder for Smart Web Components is available now.We have built a new web tool that enables you to create or customize existing themes. The Theme builder generates a CSS file, which you can download and apply to your web application. The good news is that the tool is Shadow DOM friendly, because of the CSS variables support deeply integrated into Smart Web Components.  Highlights
Using the theme builderNavigate to the theme builder application at the Theme Builder web page. The theme builder application page is divided into two main sections - theme settings on the left and preview on the right.
Advanced settingsThe advanced settings mode adds many more customization options for precise Theme design. From the left section, you can choose which component category to design and select a color for specific settings such as "Row Alternation Text Color".

The list with all changes is below:  What's New:
What's Fixed:
Breaking ChangesThe Grid API is updated with new "behavior" and "layout" categories. Some of the existing properties are moved into that categories. To migrate from previous versions to 4.5.0, we advice you to look at the Grid API Docs: https://www.htmlelements.com/docs/grid-api/. The changes are related to: rowHeight, rowMinHeight, columnWidth, columnResizeMode, rowResizeMode, showRowNumber, scrollMode.Advanced Data Visualization with Grid ChartingSmart.Chart integration with Smart.GridThe next version of Smart Web Components will bring integrated charting functionality that allows users to chart directly inside the Grid Web Component. We are happy to announce that Smart Grid is the First Enterprise Grid with such feature available. The charting is implemented through our Smart.Chart Web Component and is using the grid data source. Charts can be exported to .PDF, .PNG of .JPEG. There are two approaches to create a Chart.
Smart.ChartThe charting used in the Grid and Chart integration is our own-made Smart.Chart component. Smart.Chart is a Web Component built through the Smart Framework and is based on the broadly used jQWidgets Charting solution. It does not have any third-party dependencies. It is created by our own Team as all other UI components in our package.  Chart ToolbarThe Toolbar with Charting options is displayed in the Grid header. By clicking a Chart Type, the Grid will create it. To create Charts, users will need to import the Smart.Grid, Smart.Chart and Smart.Window modules and enable the Charting in the Grid. Below is displayed a Chart created through selection by dragging or by keyboard navigation a Cells Range of Numeric values. Charts are displayed in our Smart.Window component. You can resize it, maximize it, move it, change its header position, stick it to screen edge, minimize it or just collapse it. Smart.Window is designed to be the most feature-complete Dialog component. It can be either modal or non-modal. Below is displayed a Bar Chart created by selecting multiple rows. Below is displayed a Pie Chart created by selecting multiple columns.  Below is displayed a Column Chart by cells selection.  Charts SettingsAs our Charting solution is evolving for the last 10 years, it has quite a lot of settings and Chart types like Financial Charts, Zooming, Spider Charts, etc. You may learn more about our Charting on our demos and documentation pages.

Data Export to XLSX, PDF, CSV, TSV, XML, HTML and JSON The newest 4.2.0 version of the Smart UI toolkit includes a very important business feature - Grid Data Export. You can now export the data from your grid component to various formats. The supported formats are .xlsx, .xml, .pdf, .csv, .tsv, .html and .json. You can also import data from .xlsx file. The Export feature takes into account the Grid Style, Data Format, Data Type and whether the data is grouped by some criteria. Check out the updated Grid demos: https://www.htmlelements.com/demos/grid/data-export/. Using Web Components with Angular We are happy to announce that with the release of Smart HTML Elements ver. 4.1.0, we added "Using with Angular" example for each web component. These Angular examples are available in the Demos section and will help you to use our Web Components in your current or future Angular projects. The source code is included in the download package and can be found in the demos/angular/ folder.

'Lorem Ipsum is simply dummy text of the printing and typesetting industry.

'Why do we use it?\n' +
'It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal ' + 'distribution of letters, as opposed to using \'Content here, content here\', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their' + 'default model text, and a search for \'lorem ipsum\' will uncover many web sites still in their infancy.

Live Example in Stackblitz: https://stackblitz.com/edit/github-m7vjva-qamazf.  Define a Custom Element In this post, we will show you how to define a Custom Element with Smart Framework. We will create a Material Color Picker custom element. 1. Define the Custom Element. To define a new custom element with Smart Framework, we need to call the Smart function with two parameters - the tag name and the Class with the logic.
Smart('smart-colors', class SmartColors extends Smart.BaseElement {
}
2. Smart Framework gives us useful things like Templates, Data Binding, Typed Properties, Lifecycle callbacks, Event Handling. Read more about this https://www.htmlelements.com/docs/base-element/. In our Custom Element, we will use some of these features. We will use the 'ready' lifecycle callback. It is invoked once, when the element is attached for first time. We use this function to create and initialize the custom element. The 'properties' definition includes a property called 'color'. This property has default value - '#fff' and its type is 'string'. This means that when you try to set a 'bool', 'date', 'numeric' value, the element will throw an error with 'Invalid property type'. To raise the 'change' event, we use the '$.fireEvent' method. 3. The full code of our custom element is below
// Define Custom Element
Smart('smart-colors', class SmartColors extends Smart.BaseElement {
// Declare properties
static get properties() {
return {
'color':
{
value: '#fff',
type: 'string'
}
};
}
// Ready is called when the element is in the DOM.
ready () {

TreeGrid and GroupingTree Grid, Grouping, Context MenusThe latest version of Smart HTML Elements brings important new features to our Smart Grid Web Component. It is now possible to display data hierarchies in the web component. The Grid allows you to display data as a combination of Tree and Grid. The Tree Grid mode has full support for data sorting, data filtering and data editing. The Grouping features allows you to group data by columns. The context menu feature allows you to quickly add a context menu functionality to the Grid. Tree GridTree Grid mode allows you to display hierarchical data in the Grid and make the component work like a hybrid between Tree and Grid.  Tree Grid Virtual Tree GridIn Virtual Mode, new rows are loaded on demand when you expand a row. This process repeats until the "leaf" property of the row is set to true. Virtual Tree Grid Virtual Tree Grid PaginationWith Pagination enabled, Root rows are loaded on demand when the current page is changed. Sub Rows are loaded when a treegrid row is expanded.  Virtual Tree Grid Pagination Grid GroupingGrouping enables you to group the component by one or multiple columns. The grouping styling is customizable through CSS Variables.

Lazy Initialization of Web ComponentsThis post shows how to create a Grid Web component and initialize it from a DIV tagThe next version ver3.1.0 of Smart HTML Elements will introduce an alternative way to create a Web Component on demand from an existing HTML Element.Let's look at the sample below. In the 'index.htm' web page code, we see a HTMLDIVElement(DIV tag) with id="grid". We will use that HTML element to create a new Grid Web Component instance. <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Grid Lazy Load Demo</title> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" /> <link rel="stylesheet" type="text/css" href="../../../source/styles/smart.default.css" /> <link rel="stylesheet" type="text/css" href="../../../styles/demos.css" /> <link rel="stylesheet" type="text/css" href="../../../styles/common.css" /> <link rel="stylesheet" type="text/css" href="styles.css" /> <script type="text/javascript" src="../../../scripts/common.js"></script> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/webcomponentsjs/1.2.0/webcomponents-lite.js"></script> <script type="module" src="index.js"> </script> </head> <body> <div id="grid"></div> </body> </html> The 'index.js' file is defined as a Javascript Module. In that module our grid web component is created on window.onload, within a function called 'init()'. That is achieved by calling the Smart.Grid function and passing as a first argument the 'id' of the DIV tag and as a second argument the initialization object with the Grid web component's dataSource, columns and other configuration options. As a result, our DIV tag is replaced with a 'smart-grid' tag and a Grid is displayed. That approach is useful, when we want to update an existing application with minimum changes or to create a Smart Web Component on demand with ES6 code.

The Chart Types supported are listed: Chart Types. Our Chart Custom Element is written in JavaScript and CSS. It does not depend on any other third-party scripts. The rendering is achieved with SVG and HTML5 canvas. The Chart works well on mobile browsers and is the most feature-complete chart available in the web components world. Data displayed on the Chart can be formatted in multiple different ways. For example, the charting element has a property called 'formatSettings' with the following data formatting options.
 The image below illustrates the Axes supported by the custom element. Smart.Chart has two main types of axes - valueAxis and xAxis. Typically the valueAxis represents the vertical axis in the chart although you may choose to rotate the axes and in this case the valueAxis will be displayed horizontally.  Smart.Chart also ships with 32 built-in color schemes which are used to automatically set colors for different series. You can change the color scheme by setting the colorScheme property of the chart. The available value are from 'scheme01' to 'scheme32'. By setting its 'theme' property, users can Data Visualize their graphics in 'Light' and 'Dark' mode. Smart.Chart is based on: jqxChart. We invite you to look at our Chart Custom Element demos: Chart overview Binding to Row, Cell and Column Events in Grid Web Component This post shows how to bind to the Grid Web Component events. The code below initializes the Grid instance and binds to the 'click' event. Within the event handler, we can get details about which part of the Grid was clicked - Cell, Row or Column. This is achieved by utilizing the 'event.path' array. It is also important to note that each Data Grid Column has 'data-field' attribute and each Row has 'data-id' attribute. The data source, which is used in the example is available in the 'data.js' file from the download package. AutoComplete Input Custom Element also known as Typeahead The newest version of our framework marks the availability of a new AutoComplete Input tag. We needed such lightweight component for the purposes of our Grid web component. There, it is used as an inline cell editor. You can check it out here: grid-editing-cell-auto-complete. Here is how the web component looks like when you add it to your web page:  All you need to do is to add a reference to smart.elements.js, smart.default.css and type the following: <smart-input data-source="[South America, North America, Asia, Africa, Europe]"></smart-input> Extend Elements with Behaviors Our Web Components library has a feature, which allows you to dynamically extend a Custom Element with additional behaviors. We call them Modules. To add a new module, you have to call the 'addModule' method. In this blog, we will show you how to create a new module, which adds a 'color' property to a Custom Element. We will call it 'ColorModule'.
class ColorModule {
static get properties() {
const properties =
{
'color': {
value: 'red',
type: 'string',
observer: 'setColor'
}
}
return properties;
}
ready() {
this.ownerElement.$.root.style.color = this.color;
}
setColor(oldColor, color) {
this.ownerElement.$.root.style.color = this.color;
}
}
The 'ColorModule' defines a 'color' property. The default property value is 'red'. Whenever the 'color' property is changed, the 'setColor' method is invoked which applies the Color to the element. The below code adds the Module to the 'smart-toggle'button' Custom Element.
window.Smart.Elements.whenRegistered('smart-toggle-button', function (proto) {
proto.addModule(ColorModule, true);
});
Note that the second parameter is 'true'. This means that our 'ColorModule' will be added to all sub-classes of the 'smart-toggle-button' i.e 'smart-radio-button', 'smart-check-box' and 'smart-switch-button'. All these custom elements will have the 'color' property. Usage example:
window.onload = function() {
document.querySelector('smart-radio-button').color = "blue";
}
Get Caller JavaScript File Location If you need to get the Path to the current Javascript file being executed, you can use this small function: const location = (function () {
if (document.currentScript) {
let link = document.currentScript.src;
let lastIndex = link.lastIndexOf('/');
link = link.substring(0, lastIndex);
return link;
}
})();In our code base, we use it to dynamically load Component dependencies. Posted in: HTML Elements, Web Components Tagged: javascript, javascript code, javascript es6 Leave a comment Grid with Very Large Data Set One of the new additions to our Javascript Grid Web Component is the capability to load very large data sets. Example: Grid Large Data Set. In the example, we demonstrate how to load 50,000 rows and 1,000 columns. This can be achieved due to the built in Fast Data and User Interface virtualization. We create HTML Elements only for the View and update them while user scrolls. The Grid is also in unbound mode and the demo is created by using this code: Smart('#grid', class {
get properties() {
return {
appearance: {
showRowNumber: true
},
columnWidth: 100,
dataSource: new Smart.DataAdapter(
{
dataSource: 50000,
dataFields: 1000
}),
onCellRender(cell) {
cell.value = cell.row.index + '.' + cell.column.index;
}
}
}

To use this feature, you need to access a Grid cell, through the Grid's 'rows' array. Each row in the 'rows' array has 'cells' array. It allows you to access a cell and set options of that cell like: 'rowSpan', 'colSpan', 'backgroundColor', 'color', 'value', 'fontSize', 'fontWeight' and 'fontFamily'. Example: https://www.htmlelements.com/demos/grid/merged-cells/. Columns Crud - allows you to dynamically add, remove and update DataGrid columns. This is achieved through the DataGrid's 'columns' array which has javascript functions such as: 'push', 'pop', 'splice' for adding, removing and updating array items. Once any of these functions is called, the web component will automatically refresh itself to respond to the changes. Example: https://www.htmlelements.com/demos/grid/dynamic-columns/.
