I've noticed that if i click the delete button (IconDelete) of a RadUploadItem that is currently uploading, the item is removed from the list of files ok, but the upload continues to completion. I would expect the upload of that particular RadUploadItem to be cancelled in this scenario.
I am seeing this behaviour in th Q1 2009 release
Currently i have a workaround, which is to prevent the user being able to click the delete buttons whilst an upload is in progress:
| private void RadUpload1_UploadStarted(object sender, UploadStartedEventArgs e)
| foreach (RadUploadItem item in RadUpload1.ChildrenOfType<RadUploadItem>())
| item.IsHitTestVisible = false;
On a similar tip, i find i need to disable the 'Browse' button whilst uploading is in progress, as my users get confused when they click it and it cancels the upload! I'm currently disabling it using a similar method to the above code, but it would be nice if this functionality was directly supported by RadUpload :-)
