Hello Phil,

RadUpload does not support uploading files inside UpdatePanel/RadAjaxPanel. Please consult with the following help article on how to workaround this problem.

Hi:
I guest a little more explanation is needed.  I am basing my code on the demo:
Upload / Standard File Inputs
except I only need one file.
So, I am using the html input control to get the file name as follow (slight simplification):

<input type="file" id="feedsUpload" runat="server" name="feedsUpload" size="40" />
<br />
<asp:LinkButton ID="buttonSubmit" runat="server" Text="Submit" OnClick="feedsUploadButton_Click" />
<br />
<asp:Label ID="resultsLabel" runat="server" Visible="True" />
<br />
<telerik:RadProgressArea ID="ProgressArea1" runat="server" />
<br />

If the above is inside a RadAjaxPanel the before mentioned code behind always returns a file count of zero.  If outside a RadAjaxPanel the the count is one but, the progress area does not work.
Note that I am trying not to use the Ajax Toolkit dll.
