Gets or sets the maximum height of the links column in the popup menu. This is a dependency property.
A Double value that is the maximum height of the links column in the popup menu.
By default, BarItemLinks displayed within a popup are arranged in a single column. The MaxColumnHeight property specifies the column's height. If a column exceeds this value its bottom BarItemLink is moved to the next column. The MaxColumnHeight property is ignored until the PopupMenuBase.MultiColumn property is set to true.
The alternate way to display multiple columns is to use the PopupMenuBase.MaxRowCount property that overrides the MaxColumnHeight property.
