I would like to filter out unwanted file types in the RadUpload control. This is not the same as the AllowedFileExtensions property as this is for validating, not displaying with the "SELECT" button. When the "SELECT" button is clicked, I want to only display files that are of the type I want filtered (such as .doc or .jpg, etc.) I have researched this for awhile now and cannot find any information on how to do this. Any help would be greatly appreciated.

Hi Wize Owl,
Unfortunately, filtering the extensions is not possible due to the way browsers implement the <input type='file' />. This is browsers limitation, not RadUpload one. Since RadUpload relays on the stanrad input type = file, it inherits this fault.
The only way to have filtering, multiple file selection and other useful features, is to use Flash or Silverlight upload. Having said that, you might find this demo useful. It shows how to use Silverlight upload in an ASP.NET environment.
