RadWindow won't load page after a post back

[Duy]

I have a RadWindow that I am unable to display the contents of the URL that is specified in the NavigateUrl property after the page does a postback. When the page first loads, I can open the RadWindow with no problem. But after I click on an asp.net button, which causes a postback, the RadWindow opens but does not load the page.
 
I am using a Master page, and the content page contains a user control, that contains the RadWindowManager and the RadWindow declaration. Someone please help!!!!
 
This is the aspx  code to call the js function to open the window:

<asp:HyperLink ID="lockerSettingsLnk" Text="windowLink" runat="server"
                    NavigateUrl="javascript:showRadWindow();" />

The Javascript Function

  function showRadWindow ()
    {
        var radWindow = window.radopen(null, "myWindow");
        radWindow.argument = new Object();
        radWindow.argument.refreshParent = false;
    }

This is the aspx  code for a button:

<asp:Button ID="testButton" runat="server" OnClick="testButton_clicked"/>

This is the aspx  code for the RadWindowManager and RadWindow declaration:

<telerik:RadWindowManager id="radWindowManager" runat="server" enableembeddedskins="True">

<Windows>

<telerik:RadWindow id="mywindow" Behaviors="Close, Move, Resize, Maximize" ReloadOnShow="true" VisibleStatusbar="true" ShowContentDuringLoad="false"

Left="150px" Modal="true" Runat="server" Width="600px" Height="450px" >

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

Hello Duy,

The code that you posted looks OK and should not be the direct reason for the problem. I assume that the problem is somewhere in the logic that you are using in your project, however without having a closer look I cannot be sure.
Please, open a support ticket and send me a small sample project where this issue could be observed. I will check it and do my best to help.

It turned out that I was only setting the NaviateURL on if the page was not a postback from the code behind. Thanks!
