Catch click event in another file

Question

I have this .aspx which has a few checkboxes and textboxes and a submit button.

Using a delegatecontrol, I add some external textboxes to that page. Now, what happens when I click the submit button it sends all the information to a list, BUT the values in the textboxes added through the delegatecontrol is not affected by the submit buttons click event, so what I want to know is: Is it possible to catch the .aspx click event in the delegatecontrol?

The reason why I don't just put in the textboxes in the .aspx file is because I don't have access to the .aspx.cs file attached to it, just the .aspx file.

One thing you can do is check for the ID of the control that caused the postback with Request.Params["__EVENTTARGET"] inside of your delegate control. I'm pretty sure you can actually get the actual event that caused the postback as well.
