ASP.NET How to access the EmptyDataTemplate controls from OnRowCommand in GridView

The way of getting access to the controls in EmptyDataTemplate is similar to the way of accessing controls in the same data row in the gridview.

For example - inserting value in the empty gridview:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
 if (e.CommandName == "Insert") {
  TextBox txt  =
    (((Control)e.CommandSource).NamingContainer).FindControl("txtTest") as TextBox;

    //do insert action
 }
}

Another way to do this is by getting EmptyDataTemplate table and its controls:

if (e.CommandName == "Insert")
{
   Table table = (Table)GridView1.Controls[0];
   TextBox txtTest= (TextBox)table.Rows[0].FindControl("txtTest");

   //do insert actions
}
