Bars and item height within Gantt Chart Library and Project Management Library for WPF

In order to set the item (row) height within a component from Gantt Chart Library for WPF or Project Management Library for WPF you will need to set ItemHeight property values and optionally also BarHeight, BarMargin, and BarVerticalAlignment property values, at the control level (or at the item level, by using the similar attached properties for the appropriate control, such as GanttChartView.ItemHeight or ScheduleChartView.ItemHeight).

For example, if you want each item (row) to have a height of 100, set ItemHeight to 100 and BarHeight to 92 (allowing some top and bottom margin around the bars).
