We have written our own Vault Addins to support our business requirements. So we have our own menu items (Contextmenu, Toolbar ...)
What we need is to deactivate or activate such a menu item during runtime. At the momen it is only possible to activate or deactive a menu item during addin loading.
For example: If an item or a document fulfill a certain requirement (a property contains a certain value), only then the menu item should be activated otherwise deactivated
Thanks
