Hi all

I hav problem in CBool function what it does

Private afterCurrentCellChanged As Boolean = False
Private Sub dataGrid1_Click(ByVal sender As System.Object, _
       ByVal e As System.EventArgs) Handles DataGrid1.Click
   Dim discontinuedColumn As Integer = 0
   Dim pt As Point = Me.dataGrid1.PointToClient( _
       Control.MousePosition)
   Dim hti As DataGrid.HitTestInfo = _
       Me.dataGrid1.HitTest(pt)
   Dim bmb As BindingManagerBase = _
       Me.BindingContext(Me.dataGrid1.DataSource, _
       Me.dataGrid1.DataMember)

   If afterCurrentCellChanged _
      AndAlso hti.Row < bmb.Count _
      AndAlso hti.Type = DataGrid.HitTestType.Cell _
      AndAlso hti.Column = discontinuedColumn Then
        Me.DataGrid1(hti.Row, discontinuedColumn) = _
           Not CBool(Me.DataGrid1(hti.Row, _
                 discontinuedColumn))
    End If
    afterCurrentCellChanged = False
End Sub 'dataGrid1_Click

    'add a line to this existing handler
Private Sub dataGrid1_CurrentCellChanged( _
            ByVal sender As System.Object, _
            ByVal e As System.EventArgs) _
        Handles DataGrid1.CurrentCellChanged
    'if click on a discontinued row, then set 
    'currentcell to checkbox
    Dim discontinuedColumn As Integer = 0
    Dim val As Object = Me.DataGrid1( _
         Me.DataGrid1.CurrentRowIndex, _
         discontinuedColumn)
    Dim productDiscontinued As Boolean = CBool(val)
    If productDiscontinued Then
         Me.DataGrid1.CurrentCell = _
           New DataGridCell( Me.DataGrid1.CurrentRowIndex, _
                             discontinuedColumn)
    End If
    'add this line
    afterCurrentCellChanged = True 
End Sub 'dataGrid1_CurrentCellChanged
