Strange Ajax Behavior with Radbutton RadAjaxPanel RadAjaxManagerProxy RadAjaxManager RadScriptManager

[Matt]

I am having the hardest time getting a RadButton to invoke a function in the code-behind file, which updates the text of the RadButton.  So far I can get the button to fire with Ajax, but even though the function changes the text it is not reflected back onscreen.  Furthermore, the 2nd time I click the button the page conducts a postback resulting in a view that only shows the contents of the master page.  The content of the web form is blank.

Am I missing or have incorrect parameters?

Web Form RadAjaxPanel + RadButton

<telerik:RadAjaxPanel ID="Panel_MyList" RestoreOriginalRenderDelegate="true" LoadingPanelID="RadAjaxLoadingPanel_MyList" runat="server">
    <telerik:RadButton UseSubmitBehavior="true" AutoPostBack="true" EnableAjaxSkinRendering="false" EnableEmbeddedSkins="false" EnableTheming="false" EnableBrowserButtonStyle="false" EnableEmbeddedBaseStylesheet="false" ButtonType="LinkButton" ID="Button_MyList" OnClick="Button_MyList_OnClick" runat="server" Text="Add to Favorites" CssClass="btn btn-view" style="font-size:18px;"></telerik:RadButton>
</telerik:RadAjaxPanel>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel_MyList" runat="server" />

Web Form RadAjaxManagerProxy

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy_Tour" runat="server">

            <AjaxSettings>

                <telerik:AjaxSetting AjaxControlID="Button_MyList" EventName="Click">

                    <UpdatedControls>

                        <telerik:AjaxUpdatedControl ControlID="Button_MyList" />

                    </UpdatedControls>

                </telerik:AjaxSetting>

            </AjaxSettings>

        </telerik:RadAjaxManagerProxy>

Master Page RadScriptManager + RadAjaxManager

    <telerik:radscriptmanager ID="Radscriptmanager1" EnablePartialRendering="true" EnablePageMethods="true" ScriptMode="Debug" runat="server"></telerik:radscriptmanager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" EnableAJAX="true" runat="server" />

Hello Matt,

Please note that using RadAjaxPanel simultaneously with RadAjaxManager or UpdatePanel ( or implementing multiple wrapped RadAjaxPanels ) is not a supported scenario and we highly recommend to avoid such implementation. Please either use just the manager to update your controls replacing the RadAjaxPanel with a regular asp:Panel, or use the RadAjaxPanel alone to wrap your page.

Furthermore, if you are using a complex scenario like WebUserControls or Master/ContentPages, we recommend you to place RadAjaxManager instance on the main/master page and add a proxy control to the user control/content page as you have already done. Please also check out the following help topic:
RadAjax and MasterPage

I hope this will prove helpful. Please make the suggested modifications and let me know about the result.

Kind regards,
Eyup
