Hello Mark,

You can access the label by loop through the entire row. Here is a sample code.
C#:

protected void Next_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in rad.MasterTableView.Items)
        {
         Label lbl1=item.FindControl("Label") as Label;

        }
    }

Thanks,
Shinu.
