How can I prevent a user from resizing GridViewColumns withing a ListView control?
i found a solution and probably it will help someone else someday ;)
you have to override the GridViewColumnHeader's ControlTemplate (default template is here ) and remove the PART_HeaderGripper from the template in order to prevent resizing of your columns.
there is another solution that comes up with subclassing GridViewColumn described here. for representation purposes i prefer xaml only solutions though
