Hi,

Thank you for your post!

I think this is a known issue,It is something about Dynamicaly loading User Controls into UpdatePanel.

You can see the following threads too:

ConfirmButton and disabled controls

I've noticed that ConfirmButton reacts on clicking on disabled (Enable = false;) buttons.
Sometimes U don't want to see confirm dialog when clicking the button is disabled.
One small modification in .js does the job (one condition when binding onclick handler) but it would by nice to have it the toolkit.

Good point - I'll add a work item for that. Thanks!
