    I am using Editor (RadControls for Asp.net Ajax q2 2011) in Visial Studio 2005 project.
    I have RadScriptManager as very first control on the page and RadEditor after it.
    When i select some text and click HyperLink Manager button, i get Hyperlink dialog and after this popup Error (line 1093, Sys.WebForms.PageRequestManager is null or not an object.

    thanks

    Hello Galina,

    Please, open the web.config file and look for this line:

    <xhtmlConformance mode="Legacy"/>

    The xhtmlConformance element is usually added when an application is migrated from VS 2003 and unfortunately it is not compatible with the ASP.NET AJAX extensions (see http://weblogs.asp.net/scottgu/archive/2006/12/10/gotcha-don-t-use-xhtmlconformance-mode-legacy-with-asp-net-ajax.aspx). Remove it and see if the dialogs problem is fixed.

    All the best,
    Rumen
