    Hello, I have a RadButton which lives on a user control, which in turn is within a master page.

    I'm trying to use the RegisterPostBackControl method of the master page's RadScriptManager object to register the button, but upon clicking it still is causing a FULL postback rather than executing the button's OnClick which references a separate ExportToExcel method I've created.

    I have the Page_Load in the user control below as follows, what am I doing wrong?

            protected void Page_Load(object sender, EventArgs e)
                if (Page.IsPostBack)

    Here is the markup for the RadButton:

          <telerik:RadButton runat="server" ID="_ExportButton" Text="Export" Enabled="False" AutoPostBack="True" OnClick="ExportToExcelClick"  />

    Add below method in RadAjaxmanager/RadAjaxpanel.


    JS Code

    <script type="text/javascript">
           function onRequestStart(sender, args)
               if (args.get_eventTarget().indexOf("ExportButton") >= 0)


    If you used UpdatePanel then


    For more information please check below link.

    Let me know if any concern.

    Thanks for your reply, Jayesh!

    I tried implementing this as you suggested and it works great, but to give more detail, the Export button lives within in a RadToolTip control, which itself lives within another user control.

    It seems like the RadToolTip does not "survive" the full postback (which kind of makes sense, when a page loads fresh you wouldn't expect a tooltip to persist), so maybe this scenario isn't feasible for an export button within a RadToolTip control?

    Anyway thanks for the help, I may fall back and use a different method. If you have any ideas though please post.

    Hi Alan,

    Generally, you can persist the state of the ToolTip by manually implementing a save/load logic. In case you have difficulties achieving it, please elaborate on your specific scenario and send us sample screenshots or video demonstrating the desired behavior. Thus, we will be able to prepare a sample web site and send it to you.
