    PROJECT DESCRIPTION
    This is a small snippet how to make a modal popup using RadAlert to alert errors from code behind. One of the trouble is to separate the ajax callbacks and the normal postbacks. Tried some different options how to solve this but seems to be the easiest.
    I'm using this from a BasePage-class and all the Ajax, Window, Script-manager is in a MasterPage.

    The code is borrowed from this KB


    public void Popup(string message, string title)
    {
       var radAlertString = "radalert('" + message + "', 330, 210,'"+ title +"');";
       var radAlertScript = "<script language=\"javascript\">function f(){"+radAlertString+" Sys.Application.remove_load(f);}; Sys.Application.add_load(f);</script>";
     
       if(ScriptManager.GetCurrent(this.Page).IsInAsyncPostBack)
           ScriptManager.RegisterStartupScript(this, this.GetType(), "radalert", radAlertString, true);
        else
           Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radAlertScript);
    }
