    We are having a weird problem with the RadUpload control. It works on certain files, but when we try and upload a video or audio file we get the following:
    There is no uploaded file, or the uploaded file is invalid. Uploaded file: unknown

    Here is the init code:

    RadUpload1.AllowedFileExtensions =

    new string[0];
    RadUpload1.MaxFileSize = 5242880;
    // 5 MB
    lblInstructions.Text = string.Format(UploadInstructions, "", "5 MB");
    UploadItemType = 4;
    RadUpload1.TargetFolder =


    Please help.

    Hello mgaughan,

    I did not see what are the AllowedExtensions for RadUpload in your case.
