validation and cancelation

[Wielyanto]

Hi have anybody tried to validate the file that is being uploaded, and if it fails the validation, then we cancel the upload that is about to be going on?

I am trying to make a program that validates the file we are trying to upload, then if it fails the validation, there will be a message box to prompt the user, whether they still want to continue to upload that particular files.

FYI
I put the validation on UploadStarted, and it will call a web service to check the database, to make sure it fulfills the criteria


so does anybody know any possible way to cancel the upload?

Many thanks in advance

Hello Wielyanto,

You can cancel the upload in this way:

1.Subscribe to the UploadStarted event
2.Add the following code:

private void RadUpload1_UploadStarted(object sender, UploadStartedEventArgs e)
        {
            if (e.SelectedFiles[0].Name == "book2.jpg")
            {
                (sender as RadUpload).CancelUpload();
                return;
            }
.....
}

This example demonstrates how to cancel the upload with simple validation for a particular name.

I hope this answers your question.
