I have a page with a bunch of controls, amongst which is a textbox in which a user enters a number. There's a button which allows the user to submit the form.
I want to be able to pop-up a confirmation dialog only if the value in this textbox exceeds a certain value. I was going to use a confirm button extender but I need to be able to disable/enable it based on the value in the textbox. The problem is that the value could be changed and the user can click the submit button without the change event, or lose focus events firing at which point we are in the postback and the confirm button won't work.
How do I do this?

Alan
