Help with looping through Grid control and check ckeckbox

Hi,

I used the code below with a combobox to check checkboxes depending on utubeItemA (utubeItemA = 0,1,2 would cause checkboxes in first three rows to be checked)

How do I modify the code to do the same with the GridView control? Items is not a property of the GridView control.

  If utubeItemA IsNot Nothing Then
            For i As Integer = 0 To C1ItemA.Items.Count - 1
                If utubeItemA.Split(",").Contains(C1ItemA.Items(i).Text) Then
                    C1ItemA.Items(i).Selected = True
                    Dim CB As CheckBox = C1ItemA.Items(i).FindControl("CheckItemA")
                    CB.Checked = True
                End If
            Next
        End If

Thanks,

Victor
