The property MaxDropDownHeight is a dependency property, on 4 the combo box that controls the height of 3 the drop down list. Since it's a dependency 2 property, it's value can be set dynamically.

Have 1 you tried setting this value?

For me, the issue was that ComboBox dropdown 6 had height of 95 pixels regardles of the 5 amount of items.

My data source for the ComboBox 4 was a Collection<>, but after changing it to ObservableCollection<>, the ComboBox 3 dropdown opens showing all items.

Now also 2 the MaxDropDownHeight property works just fine.
