Simple problem (I think): I want to be able to invoke a click method on a predefined object, specifically, the bindingNavigatorDeleteItem button on the standard c# BindingNavigator. I need to intercept the delete so that I can verify that the record is allowed to be deleted. If it is, I want to invoke the aforementioned click event which does a nice job of deleting said record. If the record is not eligible for deletion, I want to abort the delete.
An engineering colleague of mine suggests that I simply add another button to the toolstrip and use it's click method (which, of course, I can get to) to check the records eligibility and call the original delete button as needed.
If there is another, better way, please pass it along.
To simply invoke the click - you should be able to use PerformClick().
I was a little lost by the other things you mentioned - can you clarify?
Instead of intercepting the toolstrip button (and leaving other techniques open to the user, such as deleting a row within a DataGrid), use one of the events on your Data Source to cancel the delete if invalid.
