[Solved] RadWindowManager and RadAjaxManager question

[John Fetherolf]

I have a page that opens another page in a modal RadWindow.  Is it possible for the page in the RadWindow to make AJAX calls to itself through RadAjaxManager?  If so could you direct me to an example of code that does this?

On the base page I have RadWindowManager setup like so:

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server">
        <Windows>
            <telerik:RadWindow runat="server" ID="winEditOrderNumber" Modal="true" Skin="WebBlue" ReloadOnShow="true"
                Title="Edit Order Number" ShowContentDuringLoad="false" VisibleStatusbar="false" Behaviors="None,Close"
                IconUrl="~/images/gridcmds/Edit.gif" Width="325px" Height="120px" ClientCallBackFunction="OrderNumberChangeCallback">
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

And the popup page has an AjaxManager like so:

        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="btnOK" />
            </AjaxSettings>
        </telerik:RadAjaxManager>

When I hit btnOK it always causes a postback and a page reload.  I checked RadAjaxManager.GetCurrent().IsAjaxRequest and it says false.

Thanks in advance for the help,
Kevin

It seems RadAjaxManager doesn't like to just postback to a button that updates no other controls on the page.  Once I make btnOK update a label on the popup page I properly get the Ajax request.  So I guess the real question is, how do you cause an Ajax request when you really don't intend to update any controls on the page?

Hi John Fetherolf,

This is a known limitation that was inherited from MS AJAX. It is outlined in this help article - for now the only workaround is to have an updated control.

That is what I figured.

Thanks for the help.
