Hi,

You can create template columns dynamically in the Page_Init event handler. To create a template dynamically, you must define a custom class that implements the ITemplate interface. Then you can assign an instance of this class to the ItemTemplate or EditTemplateTemplate property of the GridTemplateColumn object. Check the following help documentation which explains more about this.

Hi,

Here is the sample code to create a template column dynamically.
C#:

protected void Page_Init(object sender, System.EventArgs e)
{
  RadGrid1 = new RadGrid();
  RadGrid1.ID = "RadGrid1";
  RadGrid1.MasterTableView.DataKeyNames = new string[] { "EmployeeID" };
  RadGrid1.AllowPaging = true;
  RadGrid1.MasterTableView.AutoGenerateColumns = false;
  RadGrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top;
  NewTemplateColumn templateColumn = new NewTemplateColumn();
  templateColumn.ItemTemplate = new TemplateColumn();
  RadGrid1.MasterTableView.Columns.Add(templateColumn);
  GridEditCommandColumn edit;
  edit = new GridEditCommandColumn();
  RadGrid1.MasterTableView.Columns.Add(edit);
  GridBoundColumn boundColumn;
  boundColumn = new GridBoundColumn();
  RadGrid1.MasterTableView.Columns.Add(boundColumn);
  boundColumn.DataField = "EmployeeID";
  boundColumn.HeaderText = "EmployeeID";
  boundColumn.UniqueName = "EmployeeID";
  PlaceHolder1.Controls.Add(RadGrid1);
}
public partial class NewTemplateColumn : GridTemplateColumn
    {
        public void InstantiateIn(Control container)
        {

        }
    }
public partial class TemplateColumn : ITemplate
{
 public void InstantiateIn(Control container)
{
   Button btn = new Button();
   btn.Text = "Sample";
   btn.ID = "Button1";
   container.Controls.Add(btn);
 }
}

Thanks,
Shinu.
