Individual item height values in Gantt Chart Light Library

GanttChartDataGrid component from Gantt Chart Light Library defines the AreIndividualItemHeightsAppied property that allows developers to configure specific ItemHeight values on specific GanttChartItem objects.

However, because of an issue occuring inside the WPF based DataGrid control that the component internally uses, the actual data grid row presenters would all share the same height defined as the ItemHeight property value of the control, as it would be internally bound to DataGrid.RowHeight property. Although DataGridRow.Height values are correctly bound to the individual ItemHeight property values of the GanttChartItem objects internally (when they are set) and the actual vertical space of the data row would be correct, any specific height based row would be unexpectedly presented as vertically centered inside the available space, instead of stretched out to occupy it all.

To resolve the issue please follow these steps:

• Set all GanttChartItem.ItemHeight values to the appropriate values; do not let any value set to Auto (double.NaN);
• Set GanttChartDataGrid.DataTreeGrid.RowHeight to Auto (double.NaN); note that you might need to also call GanttChartDataGrid.ApplyTemplate method before, in order to be able to perform this setting.
