handling variables between client side and server side

38 New Member
I have a form, where new text boxes are generated by onclick event of a button. The function required to generate text boxes is written in Java Script. but i have to count no of text boxes generated, which can be counted only in java script. and i have to use that number in server side, this to work i wrote within script tag <script runat="server"> . now i can read the variable ,( which is in client side ), in server side, but the code related to generate text box is now not working, its giving an error, object required.

please find a solution for that.

looking forward to hear from ur side.

Everything that runs on server side runs before the page is sent to the user. After the browser gets the page and begins to interact with it (by clicking buttons for example) only the client-side script is running and no information is sent back to the server unless you specifically refresh the page or link to a new page. I hope this explains why you can't do what you are trying to do. Perhaps if you explained in more details we would be able to suggest alternatives.
