IsHierarchical: Boolean;
The IsHierarchical property returns effective value showing the use of expanders in the header.
If the Hierarchical property is set to TriState.OnOption or TriState.OffOption, the IsHierarchical property returns True or False, respectively. The effective value is calculated if the Hierarchical property is set to TriState.Undefined. If expanders are used for the parent header, the IsHierarchical property returns True, if expanders are not used, the property returns False.
The property use is given in the example for IEaxGridHeaderProperties.AutoIndent.
