Datagridview cellvalidating change cell value
When the validation fails, the editor is closed, but the user cannot change the current row in the grid until a valid cell value is entered.In this situation the editor is not kept active when the validation fails and pressing the Esc key does not revert the changes as the editor is already closed.
I would like to change the value of cell value which user inputs there and do the trim before to avoid left and right spaces over value before it will be validated. Is there a way to change the dgv cell Style Format and cell Tag from within the Cell Validating event?I've tried a few things and have searched for answers without luck so far.provides a convenient way to realize data validation before it is committed to the underlying data source.SOLUTION To achieve data validation prior the row is committed, you can handle the Cell Validating event, which is raised by the control when the current cell changes or when it goes out of edit mode.When this event is canceled in data-bound mode, the new value is not pushed to the underlying data source.
When this event is canceled in virtual mode, the Cell Value Pushed event will not be raised.
What you have to do instead is change the value in the editing control (remembering not to cancel the event).
For example, for a Your response was great and saved me lots of time.
Canceling this event prevents the user from exiting the cell until a valid value is entered or the edit process is canceled (via Esc key).
The Data Bound Item will be updated only if the cell is validated.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
