I have a database in Access that I want to display it in a Datagridview which consists of a key, date, time, and 2 more Comboboxes filled again from other tables in the same Access In the date and time fields I've put a mask to be easier to place them. If I change a value in Combobox I have in Datagridview if not the first time the second definitely stop showing the masks in the areas of time and date. The comments are welcomed Table1 ID Col1 Date Time Col4 1 1 08/04/2013 1 2 2 09/04/2013 2 3 3 10/04/2013 3 4 4 11/04/2013 4 5 5 12/04/2013 5 6 6 13/04/2013 6 7 7 14/04/2013 7 Table2 tbl2_ID tbl2_Desc 1 Desc1 2 Desc2 3 Desc3 4 Desc4 5 Desc5 6 Desc6 7 Desc7 Table3 tbl3_ID tbl3_Desc 1 Desc A 2 Desc B 3 Desc C 4 Desc D 5 Desc E 6 Desc F 7 Desc G And the code i use is this Imports System.

Close Connection) With m_Bindingsrc Detail While RFIDReader. End Edit() End While End With grddetails is the name of grid, m_Bindingsrc Detail is datasource for grd Details According to This , You should be able to force the validation trigger using Begin Edit and End Edit. I am fetching Product description, MRP and other details in cell validating. I solved this by attaching the Error Provider directly to the cell edit control like this: private Error Provider ep = new Error Provider(); private void DGV_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) private void DGV_Cell End Edt(object sender, Data Grid View Cell Event Args e) into your Business Objects, and set the Binding Source as Data Source for the Error Provider too.That way your Business Object intern validation shows up in the Data Grid and on all fields the objects are bound to automatically. 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.
