    Invalidate form

    Contour

    Hi,

    Using Contour 3.0.18, I've created a custom FileUpload field type that checks the mime types of a selected file on the server side.  

    Does anyone know the best way to invalidate the form model for invalid file types, ideally before the file is saved to the server?  

    I can supply more information if needed.

    Regards

    Phil
