Usando mesmo projeto anterior, vamos criar um CommandField Delete
Default.aspx

ShowSelectButton="True">

<asp:CommandField DeleteText="[Excluir]" ShowDeleteButton="True" />

</asp:GridView>
Default.aspx.cs
protected void GridView1_RowDeleting(object sender, System.Web.UI.WebControls.GridViewDeleteEventArgs e)
{
int id = int.Parse(GridView1.DataKeys[e.RowIndex].Value.ToString());
Response.Write("Excluir Comando: " + id.ToString());
