I am using the 12.1 WebUpload control.

The control works as excepted except if the file uploaded is too large.  In this case the UploadFinished event fires with e.FileStatus = Infragistics.Web.UI.EditorControls.UploadStatus.FileSizeExceeded.  Since the upload is not valid I return, but the page still sends a post request to "/ig_fua34sf345sdf13sdf3454erdsf2345asd3425df5235d54df345.aspx?key=qnyBdolkJb5frwLmgoRfmC0dkSh9fM&cid=5be9523d-dd21-4a3e-8788-494a72cadf82".

This post fails, resulting in Global.asax logging the failure.

As far as I can tell, this is the URL where progress updates are normally requested from.

I tried to cancel the upload, but since the UploadStarting and UploadFinishing events are not fired (goes strait to the UploadFinished event) and the UploadFinished event does not have a cancel option, this is not possible.

How do I prevent this error?  or is this a bug with the control?

Code:

Protected Sub webUpload1_UploadFinished(ByVal sender As Object, ByVal e As Infragistics.Web.UI.EditorControls.UploadFinishedEventArgs) Handles webUpload1.UploadFinished
If e.FileStatus <> Infragistics.Web.UI.EditorControls.UploadStatus.Finished Then Return ' 'If file is not finished then it is in some sort of error state and does not need to be processed.
'Process the uploaded file.
End Sub

Exception:
