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.

The validation events are meant to support the data validation of the user input.

They occur when the new content entered by the user is about to be committed.

Net 2005, Unbound Data Grid Viewer with 2 (two) columns ("Check Num" Index 0; "Clear Date" Index 1). I tried MS's Help pages and oh, those are useful (heavy sarcasm).

I would like to be able to validate the cells and force the user to put correct values in it.

Yeah, I agree with that if it is for validation only.

However, for conditional formatting code, I don't see much other way for it to remain in Data Grid View's related-code (or in a class derived from Data Grid View to abstract it).

On the other hand, the Cell Value Changed event seems to trigger only when the value of the cell changes, which means the validation code runs only when the value changes and not everytime a user changes cells.

Cancel needs to be set to True (ie, Cancel the validation) Have you set a breakpoint to ensure that wrong Input is True? And the wrong value is deleted from the Data Grid View right after checking. But is it possible to set the wrong value to a value that is accepted by the Cell Validating Event? I mean i have to check the input to see if its correct havent i?

It may be skipping over the If block In a simple test I did, it didn't seem to interfere, but I do agree that in a case like this I would rather get the errortext instead of a messagebox popping up. Or is that the way with lots of code and work x D ?

They do not occur when the Rad Grid View loads data.

The Cell Validating event occurs always before the Cell Validated event when the edited cell is about to lose its focus.

Currently the validation occurs on row and cell level.
