When I go through the loop, the last row is not displaying the calculated value, although the Cell End Edit event is fired performing the calculation and placing the values in the right cell. Thanks Hello Bob, Could you please send us your application and describe in detail the exact behavior that you want to achieve?

When I run through the loop once more, the same thing happens; the last row does not update with the current value, but displays the results of what should have been there from the previous calculation. This will help us to understand the exact scenario and to provide you with a working solution.

Selection Change Committed, _ New Event Handler(Address Of Combo Start Editing) End Sub Protected Overloads Overrides Sub Edit(By Val source As Currency Manager, _ By Val row Num As Integer, By Val bounds As Rectangle, By Val read Only1 As Boolean, _ By Val instant Text As String, By Val cell Is Visible As Boolean) My Base.

New() Column Combo Box = New No Key Up Combo Add Handler Column Combo Box.

Please, could you elaborate a bit more and describe in detail what you want to achieve. I have a grid with values in it; quantity, price, discount (%), unit price.

If the user wished to place a discount on each row, they enter it once, and then in a For Each loop, I place the value in the cell; however the calculation does not take place.

Add(text Col) Dim cmb Txt Col As New Data Grid Combo Box Column cmb Txt Col.

Edit(source, row Num, bounds, read Only1, instant Text, cell Is Visible) m Row Num = row Num cm Source = source Column Combo Box.

I handle the validation in the Cell Validating event, and if the cell is invalid display an error message, then cancel the exit of edit mode. Add(ts) End Sub End Class Public Class Data Grid Combo Box Column Inherits Data Grid Text Box Column Public With Events Column Combo Box As No Key Up Combo 'special class Private With Events cm Source As Currency Manager Private m Row Num As Integer Private is Editing As Boolean Dim str Values() As String = Shared Sub New() End Sub Public Sub New() My Base. The Data Grid View control is the new grid control for Windows Froms 2.0.However I would also like to erase the content of the cell currently in edit mode.provides a convenient way to realize data validation before it is committed to the underlying data source.The question and answers with code samples/snippets are contained in this documents only appendix to make for a one-stop shop of code. Setting Data Grid View's Datasource property should show you the grid with atleast the columns (in Grid View's heading) even when Data Table is empty. Please note that event fires only when changing the cell value using the user interface.This method will not fire when setting the cell value with code. Greetings, Jack the Telerik team Thank you for the reply.it appears as if the Cell Validating or Row Validating events are not firing.Here is my snipit of code: OK - sorry for the drawn out process. However, I am not sure that I fully understand your scenario. Regards, Jack the Telerik team I think I am looking for the same effect. No values are changed in the data source before validation.If you could paste the code that you use, it might help to debug. I just need to show a Data Grid View full of empty cells instead of a blank canvas for data to be displayed in.
