ProgressBar showing the wrong file after a few minutes

[Samwise]

Hello,

I am experiencing a weird bug right now with the RadUpload + RadProgressManager controls (.Net35 Q3 2008).

When I try to upload large files (50 Mb+), the file name displayed in the progressbar changes after a few minutes.
Apparently, it's some file uploaded by another user that is displayed.
But the upload process still manages to finish completely.
For info, my site is using the default session state and a form authentication.

Anyone has any idea of what's wrong in my web application?

Here is the declaration code of the upload controls:

                <telerik:RadUpload ID="RadUpload1" runat="server" ControlObjectsVisibility="RemoveButtons, AddButton"
                    InitialFileInputsCount="1" InputSize="30" Skin="Vista" Width="840px" OnClientAdded="addDescription">
                    <Localization Add="Select another file" Select="Browse..." />
                </telerik:RadUpload>

<telerik:RadProgressManager ID="RadProgressManager1" runat="server"                      EnableEmbeddedBaseStylesheet="False" EnableEmbeddedSkins="False"                      UniquePageIdentifier="349f6d15-ebfd-4ddc-8e99-e123a51d8646" />                  <telerik:RadProgressArea ID="RadProgressArea1" runat="server" DisplayCancelButton="True"

Skin="Vista" Width="640px">

<Localization Uploaded="Uploaded"></Localization>

</telerik:RadProgressArea>

And an extract of my web.config:

Hello Samwise,

I have tried to replicate the issue using your webconfig file and everything was correct. Then I tried to set session time out to a very short interval - again everything was correct. Are there any uncommon configurations applied on the webserver/your project? If possible, please sent us a sample project replicating your scenario thus we can  investigate the problem.

Sincerely yours,

I think I have found what was wrong. The UniquePageIdentifier property was set for no reason on the RadProgressManager control..

                    <telerik:RadProgressManager ID="RadProgressManager1" runat="server"
                    EnableEmbeddedBaseStylesheet="False" EnableEmbeddedSkins="False"
                    UniquePageIdentifier="349f6d15-ebfd-4ddc-8e99-e123a51d8646" />

I could not reproduce the bug when I removed it.:

                    <telerik:RadProgressManager ID="RadProgressManager1" runat="server" />

Thanks,
Sam

Hi Samwise,

The obscure appearance of the unique identifier is due to a bug when using smart tag to register the RadUploadProgressHandler and the RadUploadHttpModule in the web config. We are going to fix this bug in the near future.
