Cell Validating Dim header Text As String = _ data Grid View1. If the event handler for the Cell Validating event finds that the value is an empty string, the Data Grid View prevents the user from exiting the cell until a non-empty string is entered.

As part of exception/error handling, the app wants to advise the user when he/she enters a value into a DGV field that is inappropriate; for example, an alpha character in a cell containing an integer value.

When the user types in the alpha and hits enter, Begin Edit fires off, realizes the cell is dirty, and can see the previous/old cell . Data Error then promptly frags the entry (interdicting Cell Value Changed execution), but again can't say what value/ character(s) the user entered that were inappropriate.

Since the entered characters persist on the DGV (until . End Edit are called), they must be somehow accessible; can anyone explain how to grab them? Hey Roach, If you handle validation on a cellular level you can access the formatted value or cancel the validation and value being changed at all...

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.
