Here is the code for my upload control:

 

<CuteWebUI:Uploader runat="server" ID="Uploader1" InsertText="Browse for Files"
                            ManualStartUpload="true"
                            MultipleFilesUpload="true"
                            MaxFilesLimit="10"
                            OnUploadCompleted="Uploader_UploadCompleted"
                            OnFileValidating="Uploader_FileValidating"
                            TempDirectory="~/___UploadTemp"
                            CancelButtonID="ButtonCancel"
                            >
                        <VALIDATEOPTION
                        AllowedFileExtensions="jpg,mp4,mp3,mov"
                        MaxSizeKB="256000"
                        />
                    </CuteWebUI:Uploader>

 

I have this method setup:

 

     public void Uploader_FileValidating(object sender, UploaderEventArgs args)
    {
        DebugLabel.Text += "<br/>" + DateTime.Now + "FileValidating - " + args.FileName;

    }

 

And in the OnInit event, I added this (I tried without this as well):

 

Uploader1.FileValidating += new UploaderEventHandler(Uploader_FileValidating);

 

 

For some reason the event is not firing...   Any ideas?

 

Also, when this event fires should the files be ready to move?   I am doing a lot of operations (move, verify, create thumbs, etc) and the page hangs for a bit.  I can't figure out a reliable way to show a please wait message (and disable the browse/upload buttons) that will turn on once the upload button is clicked and turn off once all the operations are complete.
