    i've got a question, because im new to asp.net. Im trying to port mine app from WPF to ASP.NET, but got few issues. Im doing full ajax app, and i dont know how to achiv such scenario:

    1. Default.aspx with RadWindowManager and a DIV that will contain website later.
    2. Login.aspx just a form with login, pass and a button (it appears in RadWindow)
    3. xxxx.aspx after successful login

    so basicly in Default.cs i got 

    protected void Page_Load(object sender, EventArgs e)
                SessionUser sessionUser = (SessionUser)Session["User"];
                if (sessionUser == null)

    ShowLoginWindow() just open a RadWindow and till that everything works fine. Than in Login.aspx i use RadAjaxManager with button control to get click. Mine question starts here
    1. How can i close RadWindow form code-behind.
    2. How can i know at code-behind Default.cs that Login Window is closed, so i can load a site into DIV?

    Also how do you use modal window? Im not talking about lock screen, because there is a bool to make modal or not, but how can i do something at code-behind, than forward data to modal window, get data from window and continue to execute code.
    Something like:

    Window window = new Window();
    window.MineString = "Something";

    Ofc i know it cant be achiv like i did, but need something for such scenario.

    Thanks, for help.

    Hello Zbigniew,

    Straight to your questions:
    1. To close a RadWindow from within the content page, you need to get a reference to it and then call its close() method - basically, in the same way as you would do that with a standard popup. The only difference is that to get a reference to the RadWindow, you need to use the GetRadWindow() function instead of using the window object.
      function GetRadWindow()
        var oWindow = null;
        if (window.radWindow)
           oWindow = window.radWindow;
        else if (window.frameElement.radWindow)
           oWindow = window.frameElement.radWindow;
        return oWindow;
      function closeWin()
          var oWnd = GetRadWindow();
    2. RadWindow is created and handled on the client - it doesn't have a server-side event fired when it is closed (if it did, you would have to make trips to the server on every closing). If you want to fire a server-side event when a RadWindow is closed, you could use the OnClientClose property. There you could set a name of a JavaScript function that will be fired once the window is closed. In that JS function, you could use __doPostBack() or RadAjax's ajaxRequest call.
