hi,
I want to use your grid in our Vue application.
I want the grid on the left side of the splitter.
On the right side I want to show its details.
Therefor I have added the changed event. This event triggers my method: rowSelectionChanged()
Here I want to get the rows data, But I cannot get all the data. I only get the id. How can I get the complete data for the row?
Here is my vue template:<template> <div> <smart-splitter> <smart-splitter-item size="50%"> <smart-grid id="grid" @change="rowSelectionChanged"></smart-grid> </smart-splitter-item> <smart-splitter-item> <h1>{{ rowData }}</h1> </smart-splitter-item> </smart-splitter> </div> </template> <script> import "@smarthtmlelements/smart-elements/source/styles/smart.default.css"; import "@smarthtmlelements/smart-elements/source/modules/smart.grid.js"; export default { data: () => ({ rowData: "" }), methods: { rowSelectionChanged(event) { if (event.detail.finished) { const grid = document.querySelector("smart-grid"); this.rowData = grid.getSelection().rows[0].id; } } }, created() { window.Smart( "#grid", class { get properties() { return { grouping: { enabled: true }, sorting: { enabled: true }, filtering: { enabled: true }, selection: { mode: "one", enabled: true }, change: {}, columns: [ { label: "First Name", dataField: "firstName" }, { label: "Last Name", dataField: "lastName" }, { label: "Product", dataField: "productName" }, { label: "Quantity", dataField: "quantity", columnGroup: "order" } ], dataSource: new window.Smart.DataAdapter({ dataSource: [{ "id": 0, "firstName": "Beate", "lastName": "Wilson", "productName": "Caramel Latte", "price": 3.8, "quantity": 6, "total": 22.799999999999997 }, { "id": 1, "firstName": "Ian", "lastName": "Nodier", "productName": "Caramel Latte", "price": 3.8, "quantity": 8, "total": 30.4 }, { "id": 2, "firstName": "Petra", "lastName": "Vileid", "productName": "Green Tea", "price": 1.5, "quantity": 2, "total": 3 }, { "id": 3, "firstName": "Mayumi", "lastName": "Ohno", "productName": "Caramel Latte", "price": 3.8, "quantity": 2, "total": 7.6 }, { "id": 4, "firstName": "Mayumi", "lastName": "Saylor", "productName": "Espresso con Panna", "price": 3.25, "quantity": 4, "total": 13 }, { "id": 5, "firstName": "Regina", "lastName": "Fuller", "productName": "Caffe Americano", "price": 2.5, "quantity": 4, "total": 10 }, { "id": 6, "firstName": "Regina", "lastName": "Burke", "productName": "Caramel Latte", "price": 3.8, "quantity": 8, "total": 30.4 }, { "id": 7, "firstName": "Andrew", "lastName": "Petersen", "productName": "Caffe Americano", "price": 2.5, "quantity": 6, "total": 15 }, { "id": 8, "firstName": "Martin", "lastName": "Ohno", "productName": "Espresso con Panna", "price": 3.25, "quantity": 3, "total": 9.75 }, { "id": 9, "firstName": "Beate", "lastName": "Devling", "productName": "Green Tea", "price": 1.5, "quantity": 9, "total": 13.5 }, { "id": 10, "firstName": "Sven", "lastName": "Devling", "productName": "Espresso Truffle", "price": 1.75, "quantity": 6, "total": 10.5 }, { "id": 11, "firstName": "Petra", "lastName": "Burke", "productName": "Peppermint Mocha Twist", "price": 4, "quantity": 11, "total": 44 }], dataFields: [ "id: number", "firstName: string", "lastName: string", "productName: string", "quantity: number", "price: number", "total: number" ] }) }; } } ); } }; </script> <style> smart-grid { width: 100%; height: auto; } </style>
January 28, 2020 at 12:13 pm #100617adminKeymasterHi olaf,
I see you have the following code:this.rowData = grid.getSelection().rows[0].id;
. The Row object also has a “data” field which referts to the the data bound data.
Hope this helps.

grid.getSelection().rows[0].data
is undefined.
Where should I find the Row object?January 28, 2020 at 1:26 pm #100621adminKeymasterHi olaf,
Sorry, the correct code actually is:var rowMeta = grid.getSelection().rows[0]; var data = rowMeta.row.data;
So if you have a firstName data field, you can access it like that:
data.firstName

Im using Angualr project and have grid tree with checkboxes in that and its working perfectly even if i select the parent row checkbox it will select the all child rows checkbox automatically thats relly nice features. But now i want to get all checked = true rows and i try with grid.getSelection().rows and its always undefined in my case. can you guide me how do i get all selected rows in angualr. I do go throught the doc but there is no specific mateiral for checkbox and this mention method is not working in my case.
Im following below link for reference.

Thanks,September 8, 2020 at 5:49 am #101041adminKeymasterHi Ronak,
Checked and Selected are different. By using the “getSelection” DataGrid method will retrieve only the selected rows, if there are any.
Each data row in Smart.Grid has a “checked” boolean property. You can use it to determine whether a data row is “checked”.
