Cannot Closing RadWindow with async PostBack, help!

[Alessio]

Hi To everyone,

I am developing a radWindow with a new Page that contains a RadMenu and I want to close it server side with a Button of the RadMenu.
If I use a Full Postback (without using the RadAjaxManager) it works, but when I put the control into the RadAjaxManager the window remains open.

Working Example:
[Javascript]

function GetRadWindow() {
          var oWindow = null;
          if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
          else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz az well)
          return oWindow;
      }

[RadAjaxManager Empty]

<telerik:RadAjaxManagerProxy runat="server" ID="RadAjaxManagerProxy1">
          <AjaxSettings>
          </AjaxSettings>
      </telerik:RadAjaxManagerProxy>

[Server Side]

lblClose.Text = "<script type='text/javascript'>GetRadWindow().Close()</script>";

NB. All the controls is contained in a Panel named "pnlFull".
If I put the panelFull Events in the RadAjaxManager Control, the window will not disappear after the Click on the RadMenu.
Eg.:

<telerik:RadAjaxManagerProxy runat="server" ID="RadAjaxManagerProxy2">
         <AjaxSettings>
             <telerik:AjaxSetting AjaxControlID="pnlFull">
                 <UpdatedControls>
                     <telerik:AjaxUpdatedControl ControlID="pnlFull" LoadingPanelID="MasterLoadingPanelBig" />
                 </UpdatedControls>
             </telerik:AjaxSetting>
         </AjaxSettings>
     </telerik:RadAjaxManagerProxy>

Someone can help me????

Hi Alessio,

This issue is a general case when AJAX is used. In such a scenario I would recommend that you inject the sctipt via the static ScriptManager instance instead of putting it in a label or literal. More information on the matter is available in the following help article: http://www.telerik.com/help/aspnet-ajax/radwindow-troubleshooting-javascript-from-server-side.html. This is your code, modified and working correctly on my end: 

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager2">
         <AjaxSettings>
             <telerik:AjaxSetting AjaxControlID="pnlFull">
                 <UpdatedControls>
                     <telerik:AjaxUpdatedControl ControlID="pnlFull" LoadingPanelID="MasterLoadingPanelBig" />
                 </UpdatedControls>
             </telerik:AjaxSetting>
         </AjaxSettings>
     </telerik:RadAjaxManager>
    <asp:Panel ID="pnlFull" runat="server">
    <telerik:RadMenu runat="server" ID="RadMenu1" OnItemClick="OnItemClick">
        <Items>
            <telerik:RadMenuItem runat="server" id="RadMenuItem1" Text="close RadWindow"></telerik:RadMenuItem>
        </Items>
    </telerik:RadMenu>
    </asp:Panel>
    <script type="text/javascript">
        function GetRadWindow()
        {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz az well)
            return oWindow;
        }
    </script>

and:

protected void OnItemClick(object sender, Telerik.Web.UI.RadMenuEventArgs e)
{
    string script = "GetRadWindow().close();";
    ScriptManager.RegisterStartupScript(this, this.GetType(), "key", script, true);
}

Please note that I am using the regular RadAjaxManager, as I do not have your custom setup, but this is not relevant to the way the script should be injected.
