Prevent postback when minimizing/restoring a radwindow

[Sam]

Hi,

I have a RadWindowManager and open up RadWindows client-side through the manager control.
I'm not sure if I set a property wrong or what, but minimizing/restoring a radwindow causes the page inside the radwindow to postback.
Maximizing/restoring, moving, resizing the radwindow does not postback.  Only minimize/restore causes a postback.

The only client event I have on the RadWindowManager is OnClientBeforeClose
This is the manager:

<telerik:RadWindowManager ID="RadWindowManagerParent" runat="server" Animation="None" OffsetElementID="wrapper"
    MinimizeZoneID="DivMinimizeZone" RestrictionZoneID="TdContent" EnableTheming="true"
    AnimationDuration="250" DestroyOnClose="true" EnableShadow="true" IconUrl="~/Images/Blue/Window_Icon.png"
    PreserveClientState="true" ShowContentDuringLoad="false" ShowOnTopWhenMaximized="false"
    Width="1000" Height="650" VisibleStatusbar="false" ReloadOnShow="true" KeepInScreenBounds="false"
    Style="z-index: 2501;" Behaviors="Close,Maximize,Minimize,Move,Reload,Resize"
    OnClientBeforeClose="RadWindowManagerParentOnClientBeforeClose">
    <Windows>
    </Windows>
</telerik:RadWindowManager>

Any ideas?

Thanks!!!

Take a look at this forum thread. It should help you here.

Opening Rad Window Causes Postback

Cheers.

Sorry for the delayed response.  We got a new email server at work and all telerik emails have been going to my junk mail.

Thanks for the link, but the asker was opening RadWindows from the server-side.

And Georgi's 2 options were to use a RadAjaxManager or wire up the opening client-side.

Notice the first sentence of my post:
"I have a RadWindowManager and open up RadWindows client-side through the manager control."

So I'm already opening the RadWindows using a client-side javascript function.

Any other ideas?

Thanks!!!

Hello Sam,

What I can suggest at his point is that you remove the MinimizeZoneID property. Its functionality requires that the RadWindow markup is moved in the DOM which inevitably causes an iframe to reload. You can reproduce this behavior with the following simple code:

<asp:Button ID="Button1" Text="move first" OnClientClick="moveIframe(); return false;" runat="server" />
<asp:Button ID="Button2" Text="move second" OnClientClick="moveBackIframe(); return false;" runat="server" />
<div id="rootDiv" style="width: 500px; height: 500px; border: 1px solid green;"></div>
<iframe id="myframe" src="content.aspx"></iframe>
<div id="nextdiv"></div>

<script type="text/javascript">
    function moveIframe()
    {
        var myframe = $get("myframe");
        myframe.parentNode.removeChild(myframe);
        var rootDiv = $get("rootDiv");
        rootDiv.appendChild(myframe);
    }

    function moveBackIframe()
    {
        var myframe = $get("myframe");
        myframe.parentNode.removeChild(myframe);
        var nextdiv = $get("nextdiv");
        nextdiv.appendChild(myframe);
    }
</script>

Similar behavior can be achieved by combining a RadWindow with RadTabStrip to create a desktop-like environment, you can check out an example in this online demo.

Kind regards,

Thanks Marin; removing the minimize zone id stopped the postbacks!
