Datagridview cell validating event

posted by | Leave a comment

I have a Data Grid View in which I enter a numeric value in a cell. Formatting implies that the underlying value is unchanged but how you display it might.

Here is the order of events that occur: The following identifies the order of validation, enter/leave and begin/end edit events.

To get notified, you can use the following events exposed by the Rad Grid View control: It is important to know that each one of the validation events is fired only when the user is trying to commit new data in the Rad Grid View control.

I am validating user input in the Cell Validating event of a Data Grid View control and when the user inputs an illegal value, I show a messagebox.

Get Type returns "Data Grid View" so I tried: Msg Box(CType(sender, Data Grid View).

Once you start fighting your own code, it turns into a mess, you have to consolidate the logic and hope you didn't miss a way to bypass your checks.
