Why can't I browse type for an workflow activity variable?

I am working on a WPF app that contains a rehosted workflow designer.

When I add a new variable I can not select a custom Variable Type. When I click on "Browse for Types..." nothing happens: enter image description here

Same is for "Array of [T]". The targeted .Net version si 4.5.1. What could be the issue?

Solution

  • So, the question was kind of specific to my case but I will answer it anyway and maybe it will help someone.

    The problem was that I was using MahApps Metro style. If I remove the style applied to the combobox it then works. You could do it like this:

    myGrid.Resources.Add(typeof(ComboBox), new Style() { TargetType = typeof(ComboBox) })
