how do i determine what event caused postback

[TS]

Is there a way in debug mode to determine what event caused the postback to
occur without having an event handler for that event?

thanks

If it's a button, the ClientId of the control will be in the REquest.Form
collection.

Any control which does postback via javascript (textBox, linkbutton,
dropdownlist) will have the id in the __EVENTTARGET of the request.form
collection.

Ok, i have proven your two statements - i did not know this

But, i have a postback that occurred by hitting the enter key and posting
back, but the eventtarget is "" and the button on the form is not in the
request.form collection.

What other ways is a form submitted that will explain this? This all leads
to my discussion of why my click event is not executing on the server even
though the form is getting posted back (Re: hitting enter button while in
textbox calls correct button's click...)

Thanks for all the input, i can say i've learned something!

Ya, sometimes the enter key doesn't cause the button to click like you might
think it should.

You could use this free control to solve the problem.

And here are a couple good articles on the subject:

thank you sir.

FYI. I couldn't get these solutions to work, but i did run across one that
did: in IE 5/6 you must have at least 2 textboxes on the form and it will
work, so you just hide the extra "dummy" control.

thanks

I solved that problem by adding :
<input type="text" style="display:none">
to a page which only had one textbox and a submit button.

Now, hitting the enter key inside the textbox submits the form.
