[mathieu]

i try to set the file filtering like here :
http://www.telerik.com/help/aspnet-ajax/asyncupload-file-filtering.html
i try in to way :

this.FileFilters.Add(new FileFilter("Tous les documents accepté", typeDocumentCtrl.getExtensionAllowed().ToArray()));
typeDocumentCtrl.getExtensionAllowed()
    .ForEach(delegate(string extension)
        {
            this.FileFilters.Add(new FileFilter(extension, new string[] {extension}));
        }
    );
this.AllowedFileExtensions = typeDocumentCtrl.getExtensionAllowed().ToArray();

both or not working 
i just need it for chrome other browser would be nice but not mandatory 
i also try :

Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; };

Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function() { return false; };

but that's change nothing 

the last test was quick maybe i can test further, but i don't know how to test in a usefull way :-)

thank to help me :-)

Hello,

 
In Chrome RadAsyncUpload uses FileApi upload module that is native for the browser 
but unfortunately the browser itself does not support file filtering functionality and that is why it can not be achieve it with our control either.

Hope this will explain the issue.
