Hi,

I'm afraid I wasn't able to understand what was the desired behavior. The AjaxManager and the UpdatePanel are not set up similarly, so they produce different results. Could you be a little more specific as to what is supposed to happen when you select a file?

If you want the version with the UpdatePanel to behave like the one with the AjaxManager, you have to set it up like so:

<asp:UpdatePanel runat="server" ID="UpdatePanel1">
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="btnUpload" />
    </Triggers>
    <ContentTemplate>
        <asp:Button runat="server" ID="btnUpload" OnClick="btnUpload_Click" ClientIDMode="Static" />
    </ContentTemplate>
</asp:UpdatePanel>

<telerik:RadAsyncUpload runat="server" ID="txtImage" OnClientFileUploadFailed="onUploadFailed"
    OnClientFileSelected="onFileSelected" OnClientFileUploaded="onFileUploaded" MaxFileInputsCount="1">
</telerik:RadAsyncUpload>
