Question

I am using asp:UpdateProgress control to show progress during a button click. I am using telerik controls to ajaxify the submit button. The code sample is below:

<telerik:RadAjaxPanel ID="RadAjaxPanel4" runat="server">
  <div class="customButton">
    <asp:LinkButton ID="lbtnSave" OnClientClick="return Page_ClientValidate();" 
                    runat="server" OnClick="lbtnSave_Click" CausesValidation="true">
      <img src="../admin/images/icons/16x16/save.png" /> 
      Save 
    </asp:LinkButton>
  <div class="customButton">
</telerik:RadAjaxPanel>

My issue:

When I surround the button with the telerik:RadAjaxPanel, I have to click on the button twice. If I remove the panel, the button submits in one click. Is this happening because of the OnClientClick or one of the other LinkButton attributes or because of the surrounding telerik:RadAjaxPanel? Please help.

Turns out, this issue is related to a page-refresh-detection logic on the page. With the RadAjaxPanel, the first button click caused the logic to think that its a page refresh – consuquently, the button was not submitted.
