    is it possible to restrict the upload to only certain file types?
    i am already validating that in the handler... but would prefer to just prevent the user from selecting an invalid file type.

    Hi John,

    You can use the OnSelect client-side event to prevent the selection of files with invalid extensions. The handler validation is still required.

    Note that you have to cancel the selection of all files if more than one is chosen at one go.

    Is there anyway to do this via the kendo.upload.js?

    nice, that covers part of it.  what about on the drag over, is there anyway to detect the file extension?

    Hi,

    The select event will fire when you drop files as well. Same code applies without change.

    All the best,

    Hello,

    I did a quick test in Chrome. the list of dragged files is not available in the dragover and dragenter DOM events. It is populated only when the actual drop occurs.

    In short, we don't know what's being dragged until it's dropped.

    Kind regards,
