    I've been using the RadWindow.RadAlert as an error popup in a number of situations, usually in various RadGrid events.

    Now I have an aspx that I'm calling from within a Radgrid using a window.radopen call.  Once the window is open, it's closed by hitting a RadButton and generating a  ClientScript.RegisterStartupScript(Page.GetType(), "", "CloseAndRebind();", true) in it's OnClick event.   This is all pretty much based on your demos.

    However in this event I have error trapping and what I want to do is when the code errors out is to instead generate an error popup.  What I have within the catch statement is a RadWindowManager.RadAlert and a return.  This is not working.

    Hello Boris,

    I have tried to reproduce the unexpected behavior but to no avail. You can watch a short video with the test in the attached archive and then tell me what I am missing.

    Could you also try to reproduce the issue with the attached VS example and then paste the changes, so that I can make an investigation locally?

    Let's ignore this one.  I must have been asleep when I wrote it.  My real problem is that in my early use of radalerts I was, for lack of a better, in an Ajaxified situation whether I recognized it or not.  In this the code was not working because I was in an ordinary button-triggered postback situation, so a RegisterStartupScript method was the only way to go.  My apologies to Danail and I promise to try and not post when in a caffeine-deprived (or over-caffeinated) condition. 


    Actually I really haven't done that much with RadWindows other than copying a couple of your more basic demos.
    I'm not sure I fully understand your example either.  But I think this example might better illustrate what I could be doing wrong.  
    (I found another one of your demos that seems to work in my situation.)
    In a basic aspx I have a RadWindowManager and a RadButton.  In the code behind I have the following.  

    The commented out RadWindowManager.RadAlert is the original problem, what I was using in other applications, mostly from RadGrid events as I recall.  That fails in this situation.  The register call does work.  (I've attached an image of the entire ASPX.

      protected void RadButton1_Click(object sender, EventArgs e)
                    throw new Exception();
                catch (Exception ex)
                    ShowErrorMessage("test", ex.Message);


            private void ShowErrorMessage(string sErrorSource, string sErrorMessage)
                string s = "Error message = " + sErrorMessage;
                s = s.Replace("'", " ");
                s = s.Replace('\r', ' ');
                s = s.Replace('\n', ' ');
                string radalertscript = "<script language='javascript'>function f(){radalert('" + s + "</b>', 600, 210, '" + sErrorSource + "'); Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
                Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);                    
    //            RadWindowManager1.RadAlert("Error = " + sErrorMessage, 500, 200, "Error in " + sErrorSource, "");
