Hello,

Thanks for your interest in our products. It is a bit hard to tell, since there is not much information (for example do you need this client-side or server-side), but in any case, here is the easiest way to have a posback fire on click and then handle the UltraWebGrid Click event. You can obtain the first cell like that:

 protected void UltraWebGrid1_Click(object sender, ClickEventArgs e)
    {
        string text = e.Row.Cells[0].Text;
    }
