Hello Don,

Thank you for contacting us.

Could you please try to use regular asp UpdatePanel instead of RadAjaxManager in your User Control and verify if the issue still persists.  Also please confirm that you are placing ScriptManager control in the very top of the main page for properly ajax functioning. You could refer to the following help topic which elaborate on RadAjax and UserControls:
http://www.telerik.com/help/aspnet-ajax/ajxusercontrols.html

Also please note that the purpose of the General Feedback type of tickets is for the customers to share their opinion of our products, support, help and etc. and provide suggestions for further improvements.
The support tickets and forums are used for submitting issues you faced with our controls.
Therefore, for further tracking the problem please start a formal support ticket or a forum thread and we will address your questions as necessary.

I have a UserControl that is basically just an ASP button.  The control works fine and I can use the OnClick event to access asp methods.  The problem seems to be when I try to get it to work with a RadAjax Manager.

This is how I have it set up in the Manager:

        <telerik:AjaxSetting AjaxControlID="btnGenerate">

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="txt_Text_Message"></telerik:AjaxUpdatedControl>

            </UpdatedControls>

        </telerik:AjaxSetting>

    </AjaxSettings>

</telerik:RadAjaxManager>

This is how the control is placed on the page:

    FontBold="true" Font="Arial" FontSize="11px" ToolTip="Auto Generate Text Message from HTML Message"

    OnClientClick="return confirm('This will replace your current text.');" />

Here is the non-UserControl button I was using:
<asp:ImageButton ID="btnGenerateOld" runat="server" ImageUrl="Images/auto_generate_wide.gif" onclick="parseHTML_btn_Click" OnClientClick="return confirm('This will replace your current text.');" />

The btnGenerate works fine when it is not in the RadAjaxManager, but of course it does a full page postback.  When it is in the manager it does not do anything.
The btnGenerateOld that I was using works in either the RadAjaxManager or as a full postback.

I have worked with this all day and have just gotten frustrated.  Please help me out.
Thanks,
Don Buck
