Server Sided Problems with more Windows added dynamicly

[Marek]

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
Marek Schmidt
