how to handle datagrid item command in C#?

Can anyone share a code snippet to handle the link button with Update command in C#? The link button is a template column inside a datagrid.

ASPX code:
<asp:TemplateColumn HeaderText="Update">
<ItemTemplate>
<asp:LinkButton Runat="server" Text="Update" CommandName="Update" ID="Linkbutton1" NAME="Linkbutton1"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn
I tried the following C# code:

private void grdOrderItems_ItemCommand(Object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if (e.CommandName == "Update")
{
...
}
}

But the handler did not get called when the link button was clicked.

Good Luck.
