Csharp datagridview cellvalidating

I doesn't matter if you've edited the text in those cells or not.

One possible way around this is to strengthen your checks in the event code to only flag the error if the value is modified.

I found this FAQ entry and subclassed Data Grid View to override Process Dialog Key().

If the key pressed is Enter, I call End Edit(), otherwise I call base. It works great, except the Cell Validating event isn't fired. Column Index = 1 Then Dim i Row As Integer = My Base.

The new object's Begin Edit() has been called, which is expected and OK.

The problem is that the End Edit() of the object that used to be under row four is never called, which is unexpected and not OK. Other than calling End Edit() in response to one of the grid's events (in this case the column header's), is there any other solution? As you experts probably know, the Cell Validating event triggers not just when a user EDITS a cell, but seemingly any time a Cell is selected.

What's the best place to implement validation logic code and conditional formatting code for a Data Grid View?

In a lot of books and articles that I've read on this control, it seems to suggest that the appropriate event to handle for this is the Cell Validating one. However, this event triggers a bit too often for my tastes and I'm not sure it is required.

I have a Data Grid View with a Date (Date Time) Column. When a user edit the cell and change the date I woulk like to allow him to write "081501" and programmatically transform the entered date to "2008/15/01"( using a custom method *called Transform Date(string ARaw Date)) But I can't find any Data Grid View event to call the Transform Date method and replace the user input by the computed value. Does anybody if this kind of transformation *is possible in a Data Grid View and Where is the best place to put the call to the transformation method ? Cell Parsing happens between the screen and the data source. When a user edit the cell and change the date I woulk like to allow him to write "081501" and programmatically transform the entered date to "2008/15/01"( using a custom method called Transform Date(string ARaw Date)) But I can't find any Data Grid View event to call the Transform Date method and replace the user input by the computed value. Does anybody if this kind of transformation is possible in a Data Grid View and Where is the best place to put the call to the transformation method ? here I've gone for a simple "replace abcdef with ab/cd/ef" approach.
