One work around can be to assign the value in a hidden field and then use it in your javascript function.

I tried using textbox also..still same prob... could u tell me why that error message comes?

You may try from the code behind also (C#.net) string dateFormat=ConfigurationManager.AppSettings["DisplayDateFormat"]; txthidden.Value=dateFormat;

value="<%$ AppSettings : DisplayDateFormat %>"

Also You may try with single quotes, instead of double quotes.

hi Apurva, i get the following error: Literal expressions like '<%$ Configuration.ConfigurationSettings.AppSettings["DisplayDateFormat"]%>' are not allowed. Use " /> instead.

Have you put that value part in single quotes if so then remove it and then try.

on runtime ie when u take document.getElementById('txtName') the value of txtName will be different, thats why you are getting a undefined error. take viewsource and find out the value of the hidden field first and then give that name. it will be somethinglike ctl00$MainContent$txtDateSearch Biju S
