What do I do If the value of a datagridviewcombobox is not in the datagridviewcomboboxcolumn datasource?

Question

I've got a situation where the drop down list has to contain only 'active' objects. However this doesn't mean the current combobox value will be in the list (it was selected at a time that object was active, but is not active anymore).

As things are now, there's an exception thrown.. I think in the dataerror handler of the datagridview, that says the value is not in the list.

What I need to do is find some event that is fired when each datagridview row is populated, so I can check and see if the combobox value is in the combobox datasource... if not, I'd add it. That's the only solution I can see. But the question is, which event handler should I use for this?

Preferably, I'd like to be able to generalize this check and put it in a class that inherits from datagridview. This way, I won't have to worry about this problem ever again.

Any ideas?

You could try the DataBindingComplete event. Other options include DataMemberChanged and DataSourceChanged.

It's a bit hard to tell which event would be the most appropriate without seeing some code.
