Clear Selected Files

[Meerkat]

Hello,

I am slightly embarrased about asking for help on something so basic and probably obvious, but could you please tell me how to clear the list of Selected Files programmatically.

 

Obviously the user does not want to see the last files he uploaded each time the RadUpload is made visible to him.

Many thanks,

Pete.

Hello Pete,

Have you tried clearing the Upload Items collection? The code may look like this:

        private void Button1_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            RadUpload1.Items.Clear();
        }

I hope this helps.

Hello Konstantin,

Many thanks for your quick response.

Your suggestion was almost perfect.
The list of Selected Files were certainly cleared, but the Total bar, showing the number of bytes previously downloaded is still visible.

Could I once again take advantage of your kindness and ask how to clear this bar as well.

Best regards,

Pete.

Hi Pete,

You can use the CancelUpload method.

radUpload.CancelUpload();

It clears the currently selected files but also will cancel any ongoing upload, so you can call it when no upload is going on to clear the items.

Otherwise the Items.Clear() should also hide the total progress bar.  Thanks for bringing our attention to this, it has been logged as an issue.

Best wishes,

Cheers Miroslav,

CancelUpload() did exactly what I wanted :-)

Many thanks for your extremely quick reply.

I have some validation in FileUploadStarting event. Which is to check whether is there a file uploaded with the same name as

e.UploadData.FileName if so i want to cancel the upload (or just give the option for user via RadConfirm messagebox)
 on FileUploadStarting event i tried to do this using (sender as RadUpload).CancelUpload() this error out the 
Application

Any solution for this

Thanks a lot

Hi Ravindranath,

Have you tried using the Validate event of the RadUploadItem? It is raised for every RadUploadItem before uploading it. You can choose to cancel or not the item and it will not be uploaded. You can subscribe to this event either with the EventManager class or with AddHandler method.

Kind regards,
