    Hi,

    I am using Radcontrols for asp.net ajax.

    In a particular page, when i click on the button it gives the following error in a popup,

    Sys.webforms.pagerequsetmanagerparserexception.

    i have attached the screenshots also.

    it dosen't give the error in the Internet Explorer. the error comes only in the Firefox.

    How can i solve the problem?

    Thanks,
    Mano

    Hello Mano,

    Here are the most common reasons for getting PageRequestManagerParserErrorException:

    -    Calls to Response.Write()
    -    Calls to Response.Redirect()
    -    Response filters
    -    HttpModules
    -    Server trace is enabled
    -    Calls to Server.Transfer()

    It is hard to say what is causing this problem without seeing some code. Can you please open a support ticket and provide a sample app that recreates this problem or post some sample of your code here in this thread. We will check it and do our best to help.

    Sincerely yours,
