    I am trying to filter the allowed files to upload depending on the media library that has been selected. (docs, images, videos, etc)

    I have the radasyncupload control in a modal window. Switching between media categories is done with a button for each cat. I tried to change the AllowedFileExtensions property there for each media type but it didn't work. Should I set it somewhere else?

    Also, how could I change FileFilter description and extensions in codebehind? is it even possible? i tried using Eval("desc/ext") but I have must missed something. 

      <telerik:FileFilter Description="Images(jpg;jpeg;png;gif)" Extensions="jpg,jpeg,png,gif" />

    Any suggestions would be appreciated it. I am thinking in doing a radasyncupload control for each media type and just hide/display accordingly but I would like to avoid that.

    Hello Esteban,

    In general we strongly recommend using the AllowedFileExtensions property instead of the FileFilters. I've prepared a sample page showing how to change the AllowedFileExtensions dynamically upon button clicking.

    All the best,
