I've made a custom propertystring-picker which inherits from PropertyStringControl. This works fine in on-page edit, it opens a dialog where I do all my stuff. But in forms-edit, I get the button "Click the button to edit", however, this can be solved by marking the property with a uhint and editordescriptor, and I can create my own dialog. But, this isn't a good solution for "on-page-edit". Because if I add a Uhint, I'll get an extra annoying dialog.
So, is it possible to use Uhint only in forms-mode, and disable it in "on-page-mode"?
