How do you get reference to progressbar and cancel button inside AJAXUploader control? We want to hide cancel button and progressbar when upload is complete. I've used LayoutTemplate for AJAXUploader. And at what point we should hide cancel button progress bar?

<eo:CallbackPanel runat="server" id="CallbackPanel1" Triggers="{ControlID:AJAXUploader1;Parameter:}">
<eo:AJAXUploader id="AJAXUploader1" runat="server" AutoUpload="true" MaxDataSize="30000" TempFileLocation="~/eo_upload" Width="400px"
ClientSideOnProgress="CustomProgressHandler">
<LayoutTemplate>
<asp:PlaceHolder ID="InputPlaceHolder" runat="server" />
<asp:PlaceHolder ID="ProgressTextPlaceHolder" runat="server" />
<eo:ProgressBar ID="ProgressBar" runat="server" Height="18px" Width="200px" BorderStyle="Solid" BorderWidth="1px"
IndicatorColor="151, 198, 232" ClientSideOnTaskDone="UploadCompleted" />
<asp:Button ID="CancelButton" runat="Server" Text="Cancel" />
</LayoutTemplate>
</eo:AJAXUploader>
</eo:CallbackPanel>

Thanks,
