Vb.net VB DataGrid-选中行时

我正在使用VB framework 2.0开发一个移动设备项目。DataGridView不可用-它是我正在使用的DataGrid

现在，我想知道在选中一行时如何执行某些操作。我试着这样想：

Private Sub MyGrid_CurrentCellChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyGrid.CurrentCellChanged
    SelectedRow()
End Sub
Private Sub SelectedRow()
    Dim SelectedRow As Integer = MyGrid.CurrentRowIndex
    Dim numCellsSelected As Integer = 'How do i count the number of selected cells in the row above?
    If *numCellsSelected on SelectedRow* = 5 Then '5 is the number of cells
        MsgBox ("Row " & SelectedRow & " is selected!")
    End If
End Sub

我是否在正确的轨道上，和/或我如何做到这一点
