e.Row.Items[4].Template = objCustomItemTemplateDelete;
}

public class EditCustomItemTemplate : ITemplate
{
public string ID { get; set; }
public string CommandArg { get; set; }

public void InstantiateIn(Control container)
{
ImageButton p = new ImageButton();
p.ID = ID;
p.EnableViewState = true;
p.CommandArgument = CommandArg;
p.CommandName = "Edit";
p.ViewStateMode = ViewStateMode.Enabled;
p.ImageUrl = "Edit.png";
container.Controls.Add(p);
