C cellvalidating cancel
For more information about how to handle events, see Handling and Raising Events. Error Text = "Invalid format" songs Data Grid View. If the row does not pass validation, set the Cancel Event Args. Canceling this event prevents the Row Validated, Control. Validated events from occurring, and also prevents the user from leaving the invalid row and prevents the row from being saved to an external data source in data bound mode.
here is a line copied from the documentation: "The Key Press event is not raised by noncharacter keys; however, the noncharacter keys do raise the Key Down and Key Up events." My guess is that the gun is sending some noncharacter data to you.
framework 3.5 C# C# data Grid View Cell Validating event fires regardless of Causes Validation set to false of Cancel button I have the Cancel buttons Causes Validation set to false but the above event still fires. First of all - The validating events of a control CAN be supressed by setting the Causes Validation = false of the other control that gest focus to. For example if you do not want the validation event of a Text box to fire when you click the Cancel button ( as you would ), then you must set the btn Cancel.
The Cancel buttons Causes Validation does not refer to the behaviour implemented by Cell Validating event on the Data Grid View. For all who tried to answer - Thanks for the attention. But for the record and others who may stumble upon , I am writing this note.
Also note that the "trick" to closing the form is not keeping a seperate "canceling" flag, but to put "e.cancel=False" in the forms closing event.
