I'd like to invoke a button click event on an ASP page programmatically, using c#. I don't have access to the server-side of the page, so i can't invoke the function directly. Is it possible at all?

in your script, call:

__doPostBack("<%= your_button_id.UniqueID %>", "");

As far a s I understand your question:

• you cannot really generate a serverside event call from the client side.
• you can force post back by using a submit button
• BUT using

  javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(...))

  may fit your need. This is the JS call that an ASP control use. copying that call may "invoke" the method you need

read more here: WebForm_PostBackOptions documentation

Enjoy!

Thanks for the answers,
I've used "Tamper Data" add-on for Firefox to see how the generated Post looks like, and built HttpWebRequest of my own.
