provides a convenient way to perform validation before data is committed to the underlying data source. You can validate data by handling CellValidating
event which is raised by RadGridView
when the current cell changes or when the cell loses input focus (when pressing Enter key). Canceling this event prevents the user from exiting the cell until a valid editor value is entered or the edit process is canceled. Please refer to the following help article for further information: https://docs.telerik.com/devtools/winforms/controls/gridview/editors/data-validation
If you are still experiencing any further difficulties, it would be greatly appreciated if you can provide more information about the precise case and how exactly the grid is setup on your end. Providing some sample code snippet for the grid's initialization and data validation would be also quite useful. Thank you in advance for your cooperation.
I hope this information helps. If you need any further assistance please don't hesitate to contact me.
