Dear Telerik,

i had a problem using server sided dynamic radwindow opening.

Scenario: We have a RadMenu. If i click on an menu Item a dynamicly added window should shown. The RadMenu updates the RadWindowManager through Ajax using RadAjaxManager.

At first, here are some relevant code in the aspx file:

Registring componetes in RadAjax Manager:

    
            <telerik:RadAjaxManager ID="RadAjaxManager" runat="server" > 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="MainMenu"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="WindowManager" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>

RadMenu and WindowManager:

    
             <div id="menuDiv"> 
        
                 <telerik:RadMenu ID="MainMenu" runat="server" OnItemClick="RadMenuOnItemClick" Width="100%" /> 
        
            </div>  
        
            <div id="windowZone" runat="server"></div>  
        
            <telerik:RadWindowManager ID="WindowManager" EnableViewState="true" runat="server"  RestrictionZoneID="windowZone" ></telerik:RadWindowManager>

The RadMenuItems added in code behind. Here is the function called if an item clicked

    
             protected void RadMenuOnItemClick(object sender, RadMenuEventArgs e) 
        
                    { 
        
                        switch (e.Item.Value)  
        
                        { 
        
                            case "wima_wiki": 
        
                                RadWindow rw = new RadWindow(); 
        
                                rw.Title = "Test"; 
        
                                rw.ID = "testwin1"; 
        
                                rw.VisibleOnPageLoad = true; 
        
                                rw.Width = 500; 
        
                                rw.Height = 500; 
        
                                WindowManager.Windows.Add(rw); 
        
                                break; 
        
                            case "wiki_bookmarks": 
        
                                RadWindow rww = new RadWindow(); 
        
                                rww.Title = "Test2"; 
        
                                rww.ID = "testwin2"; 
        
                                rww.VisibleOnPageLoad = true; 
        
                                rww.Width = 500; 
        
                                rww.Height = 500; 
        
                                WindowManager.Windows.Add(rww); 
        
                                break; 
        
                        }

If i click on one Item, the window appears dynamicly without a page reload. Great! But when i clicked on an other menu item, the second window appears, but the first window disappears.
I need all opened windows should stay open unless you realy want to close them.

I tried to set following window manager properties on page_load:

    
            WindowManager.DestroyOnClose = true; 
        
            WindowManager.EnableViewState = true; 
        
            WindowManager.RegisterWithScriptManager = true; 
        
            WindowManager.PreserveClientState = true;

The windows still close if i open another, but the position of the windows stayes the same as befor.

What i must do that the windows doesent close when i open another? Must i save the window collection into state?

Thanking you in anticipation

Best regard

Hi Marek ,

Are you using the latest version of the controls? I tried your code with it and everything is working as expected (see attached movie).

Hi Georgi,

it testet now the server-side opening methods and i still have some problems. I do the ajaxcall through the RadAjaxManager same as in the post berfore. The AjaxCall happens, (i see it also at an loading panel i added which appears), but after that loading panel disappears, the browsercontent flickers and the radwindows reloads theire content and jump from default to last "moveto" position.
I need that the content stays the same (like when i added a new windows through client-sided radwindow functions).

What can i do to avoid those reloads and flickerings ?

Also i have problems destroying the windows. When i close them, they comes back again after a new window opened. How can I remove them from the WindowCollection? Must i use client side functions to really kill them out of the windowcollection?

Best regards
