You can edit the template column value by defining the Field for that particular column.
In the below demo, the ShipCountry column is rendered with the template.
<ejs-grid id="Grid" dataSource="@ViewBag.DataSource" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">
<e-grid-editSettings allowAdding="true" allowDeleting="true" allowEditing="true" mode="Normal"></e-grid-editSettings>
<e-grid-columns>
<e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" textAlign="Right" width="100"></e-grid-column>
<e-grid-column field="CustomerID" headerText="Customer ID" type="string" width="120"></e-grid-column>
<e-grid-column field="Freight" headerText="Freight" textAlign="Right" format="C2" editType="numericedit" width="120"></e-grid-column>
<e-grid-column field="ShipCountry" headerText="Ship Country" width="150" template='#template' editType='dropdownedit'></e-grid-column>
</e-grid-columns>
</ejs-grid>
<script id="template" type="text/x-template">
<a href="#">${ShipCountry}</a>
</script>public IActionResult Index()
{
ViewBag.DataSource = OrderDetails.GetAllRecords();
return View();
}
