I don't want any validation for the edit box to be executed. Here is an important detail: if the validation fails, then If the validation occurs when the edit box loses focus, nothing about the the cancel button is going to stop that from happening.However, if the failing validation is preventing the cancel button from doing its thing, set the for the cancel button and all the parents of the cancel button. It seemed that if the user was in the middle of editing a field that was using validation and just decided to give up (leaving the field with an invalid input), the cancel button event was being fired but the window would not close down.What you have to do instead is change the value in the editing control (remembering not to cancel the event).

Because there is no Cancel argument on the parameters for the Row Leave event, I can manage to catch the error and throw up a message, but I am unable to stop it from happening in the first place. Thanks, Matt Cor, Unfortunately, validating isn't my issue.

I can check to see that there is an issue, and throw the appropriate error message if there is.

Response Property Gets or sets a value indicating the response to a question represented by the event.

I would like to manipulate a cell in my Data Grid View when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.

Thanks, Matt In many places in my application, I have a Data Grid View which users can either enter data into or use as a method of navigation in a master/detail form view.I am able to validate my value properly but when I try to change it to something valid I get a Data Error. You should never attempt to change the cell value in the handler for this event, because unless you cancel the event (in which case the user is stuck in edit mode), the cell value is set to the value from the editing control immediately after the event finishes.This, therefore, undoes any action you perform in the handler.Handle the Cell Validated event to perform post-validation processing.For more information about handling events, see NIB: Consuming Events.Response: False _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed _data Grid View_User Added Row _data Grid View_Cell Value Needed(): Row = 0 Question Event Args.Response: True _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed _data Grid View_Cell Value Pushed _data Grid View_Row Validating _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed(): Row = 0 Question Event Args.Response: True _data Grid View_Cell Value Needed _data Grid View_Cell Value Needed(): Row = 0 Question Event Args.Response: True _data Grid View_Cell Value Needed(): Row = 0 Question Event Args.
