What I wound up doing (thanks to Fabio's link) was to do the validation in the Lost Focus of the container (like I was before). However, if the validation fails, then I added a NODEFAULT. That seemed to do the trick.

Thanks for your suggestion though!

>>Sorry about the confusion. What I meant to say was that Yes, I want to allow the user to click on the button that is part of my control but No, I do not want to allow the user to click on any other buttons on the form that are NOT part of the control.
>>
>>In other words, if the form has 2 controls on it, 1 - a Save button that commits the changes that have been made and 2 - my control (which contains a textbox and button), the user should be allowed to click my control's button with invalid data to pop up a list of valid options but should not be allowed to press the Save button.

>>Hope that makes more sense.
