The recursive call seems to be in the wrong position, try to move it one line down

Private Function findControl(c As Control)

    For Each k As Control In c.Controls
        If TypeOf k Is DropDownList Then
            If CType(k, DropDownList).ID = "C1" Then
                CType(k, DropDownList).SelectedItem.Value = 2
            End If
        End If
        findControl(k)
    Next

    Return ""

End Function
