How to Render ColorPicker When Editing Record in JavaScript Grid?
You can render the ColorPicker component for a particular column while editing a record using the “Cell Edit Template” feature of JavaScript Grid component.
This is explained in the following sample code in which the ColorPicker component has been rendered using the “column.edit” property. The “rowDataBound” event triggers every time the row is bounded with data. Inside this event, the color value can able to be applied to the cell background.
JS
var grid = new ej.grids.Grid({
dataSource: data,
toolbar: ['Add', 'Edit', 'Delete', 'Update', 'Cancel'],
editSettings: { allowEditing: true, allowAdding: true, allowDeleting: true },
columns: [
{ field: "OrderID", isPrimaryKey: true, headerText: "Order ID", width: 90 },
{ field: "CustomerID", headerText: "CustomerID", width: 90 },
{ field: "EmployeeID", headerText: "Employee ID", width: 90 },
{
field: "Color", headerText: "Color",
edit: {
create: function () {
elem = document.createElement('input');
return elem;
},
destroy: function () {
colorPickerObj.destroy();
},
read: function () {
return colorPickerObj.value;
},
write: function (args) {
colorPickerObj = new ej.inputs.ColorPicker({
value: args.rowData[args.column.field]
});
colorPickerObj.appendTo(elem);
}
},
width: 90
}
],
rowDataBound: rowdatabound,
});
grid.appendTo('#Grid');
function rowdatabound(args) {
var colIndex = grid.getColumnIndexByField("Color"); // Get the column index for Color
var colorTd = args.row.querySelectorAll("td.e-rowcell")[colIndex];
// Get the cell from Grid rows
var color = colorTd.innerText;//get the colour value of the cell
colorTd.innerHTML = "<div style='padding:3px'>" + color + "</div>";//Append a div element inside the colour Td element
colorTd.querySelector("div").style.backgroundColor = args.data.Color; // Apply the background colour to the div element inside the td
}
