Confirm dialog will return true if you have clicked yes and false if clicked No button.

Hey to your first question ..

Add a literal control at the end of your aspx page and set your script where ever you need
like

literalcontrol.text = your javascript code and once done you need to make that blank again.

@Karthik
I am not getting error...however , my JS is not getting called either.....its not working still :(

Basically, what i need is:

On my Text Change Event if my control goes in the else condition written then i should get a confirm pop up asking user if he/she wishes to continue ...if the user selects yes then the rest of the activity follows or else the user is return.

I am unable to achieve this ....since yesterday...am not understanding where am i going wrong!


Thanks
