Reply To: DataGrid Header

Hi Casper,
It is better to give us a bit more context and idea on what you are exactly trying to achieve with the grid header.
However I have made a quick code example on how to have basic setup for the grid header and I have used this demo for base: https://www.htmlelements.com/demos/grid/overview/
//In your JS file :

window.Smart('#grid', class {
    get properties() {
        return {
            behavior: { columnResizeMode: 'growAndShrink' },
            appearance: {
                alternationCount: 2,
                showRowHeader: true,
                showRowHeaderSelectIcon: true,
                showRowHeaderFocusIcon: true
            },
            paging: {
                enabled: true
            },
            pager: {
                visible: true
            },
            sorting: {
                enabled: true
            },
            editing: {
                enabled: true
            },
            selection: {
                enabled: true,
                allowCellSelection: true,
                allowRowHeaderSelection: true,
                allowColumnHeaderSelection: true,
                mode: 'extended'
            },
            dataSource: new window.Smart.DataAdapter({
                dataSource: window.generateData(500),
                dataFields: [
                    'id: number',
                    'firstName: string',
                    'lastName: string',
                    'productName: string',
                    'quantity: number',
                    'price: number',
                    'total: number'
                ]
            }),
            columns: [
                {
                    label: 'First Name', dataField: 'firstName', columnGroup: 'name'
                },
                { label: 'Last Name', dataField: 'lastName', columnGroup: 'name' },
                { label: 'Product', dataField: 'productName', columnGroup: 'order' },
                { label: 'Quantity', dataField: 'quantity', columnGroup: 'order' },
                { label: 'Unit Price', dataField: 'price', cellsFormat: 'c2', columnGroup: 'order', formatFunction(settings) {
                        const rowId = settings.row;
                        const columnDataField = settings.column;
                        const template = settings.template;
                        if (settings.value >= 4) {
                            settings.cell.background = '#00A45A';
                            settings.cell.color = '#fff';
                        }
                        else if (settings.value < 2) {
                            settings.cell.background = '#DF3800';
                            settings.cell.color = '#fff';
                        }
                        else {
                            settings.cell.background = '#FFFDE1';
                            settings.cell.color = '#333';
                        }
                        settings.value = '$' + new Number(settings.value).toFixed(2);
                    }
                },
                { label: 'Total', dataField: 'total', cellsFormat: 'c2', columnGroup: 'order', formatFunction(settings) {
                        const rowId = settings.row;
                        const columnDataField = settings.column;
                        const template = settings.template;
                        if (settings.value >= 20) {
                            settings.cell.background = '#00A45A';
                            settings.cell.color = '#fff';
                        }
                        if (settings.value <= 5) {
                            settings.cell.background = '#DF3800';
                            settings.cell.color = '#fff';
                        }
                        else {
                            settings.cell.background = '#FFFDE1';
                            settings.cell.color = '#333';
                        }
                        settings.value = '$' + new Number(settings.value).toFixed(2);
                    } }
            ],
            columnGroups: [
                { label: 'Customer Name', align: 'center', name: 'name' },
                { label: 'Order Detals', align: 'center', name: 'order' }
            ]
        };
    }
});
window.onload = function (){
    const grid = document.getElementById('grid');
    grid.header.visible = true;
    grid.header.buttons= [ "columns", "filter", "group", "sort", "format", "search" ]
    grid.header.template = '<span> Your Header Template </span> <button> Click me </button>'
}

The HTML file is the same as the one from the demo.
