[Solved] ImageButton CommandArgument is Blank in GridView in ASP.Net

hi

I use imagebutton in gridview that when I click on it, it delete row of gridview...

below is code...

    protected void DeleteCustomer1(object sender, EventArgs e)
    {
        ImageButton IMGDelete = (ImageButton)sender;
    }
    private void DeleteProduct(ImageButton IMGDelete)
    {
        using (SqlConnection conn = General.GetConnection())
        {
            using (SqlCommand cmd = General.GetCommand("ProductInfo_DeleteInfo", conn))
            {
                cmd.Parameters.Add("@ID", SqlDbType.VarChar).Value = IMGDelete.CommandArgument;
                GridView2.DataSource = GetData(cmd);
                GridView2.DataBind();
                this.GetCustomersPageWiseP(1);
            }
        }
    }

but when I click on imagbutton it didn't do any thing...

I put break point and checked @ID value that was "_page" and I checked  IMGDelete.CommandArgument value was ""...

where is problem?

I used .CommandArgument  for Linkbutton in other page I don't know is it right to use it for imagebutton?

Best Regards
