I have a page with 2 controls, a textbox and a button. I would like the button pressed event in the code behind to take the text in the textbox and pass it as an argument to a javascript function i have written that should then execute. Is this possible? 

If I understand your question correctly, yes its possible.

I will code for you if you develop the scenario and post it here..

so post what you will like in your code behind and which javascript you want to pass the text to.
