    Hello Vinamra,

    Hmm, I copied the LinkButton and Window code from your example and it worked after I put a RadScriptManager on the page.  Can you try putting that on the page and seeing if it fixes your problem?

    actually i am using radscriptmanager
    well i solved my problem as OpenerElementID requires control's ClientID and i was putting only control id not the client id.

    so it worked
    but i hav different problem.
    No Servertags are working <%= RadPanel1.ClientID%> is working. i dont know why but hav to use search client id from html and i am using client id it shows this error

    The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

    Hi vinamra,

    This error is expected - the framework will not allow you to have such code in the head section that has the runat=server property set. You you could do is:
    1. Remove the runat=server setting for the head section
    2. Move your code in the body
    3. Use RadCodeBlock/RadScriptBlog.
