validating control value in grid cell

I''m adding custom controls to grid cells and the grid seems to be eating the events that normally would fire for the control, including the control''s validating event -- this is the event I would prefer to use for validation. Since this was not working I attempted to use the CurrentCelllValidating event, but this does not fire for this cell. How do I validate the grid cell? If possible, I''d prefer to use the control''s validating event. Here''s what I''m doing: Dim newCustomControl As New CustomControl Me.Controls.Add(newCustomControl) AddHandler newCustomControl.Validating, AddressOf newCustomControl_Validating With grdOptions.Item(rowIndex, colIndex) .CellType = "Control" .Control = newCustomControl .CellValueType = GetType(String) End With Thanks.

Hi Jenny, Typically this types of error occurs if you are not properly handle CurrentCell.IsModified flag. Without setting the CurrentCell.IsModified = true, your saveCellInfo is not called when you leave the cell the control which means your changes were not being saved in the grid. SaveCellInfo event fires the CurrentCellValidating Event. Please try this code in CurrentcellMoving Event Private Sub gridControl1_CurrentCellValidating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles gridControl1.CurrentCellValidating Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell Dim user As UserControl1 = CType(IIf(TypeOf cc.Renderer.Control Is UserControl1, cc.Renderer.Control, Nothing), UserControl1) If Not user Is Nothing Then MessageBox.Show(user.Uservalue,"Selected Language") End If End Sub Private Sub gridControl1_CurrentCellMoving(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.GridCurrentCellMovingEventArgs) Handles gridControl1.CurrentCellMoving Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell If cc.MoveFromRowIndex = 1 AndAlso cc.MoveFromColIndex = 1 Then Dim user As UserControl1 = CType(IIf(TypeOf cc.Renderer.Control Is UserControl1, cc.Renderer.Control, Nothing), UserControl1) If Not user Is Nothing Then cc.IsModified = True End If End If End Sub Here is a sample. http://www.syncfusion.com/Support/user/uploads/VBControlValidating_49578baf.zip Let me know if you have any more questions.

Setting the IsModified property in CurrentCellMoving was just what I needed. Thanks!
