    When I view the demo AsyncUpload - Validation, clicking Select opens a file dialog with the files filtered by the extensions. Yet according to the source, it does not make use of File Filtering.

    A similar project found at the bottom of this thread also specifies AllowedFileExtensions, but no filtering occurs. How does the online demo perform the filtering?

    Hi Jay,

    The AllowedFileExtensions property of RadAsyncUpload lists the valid file extensions for uploaded files. When the AllowedFileExtensions property is set, RadAsyncUpload automatically validates the extensions of selected files and it will move any files with disallowed extensions to the InvalidFiles collection.
