Returns the height of the sub-section after the AutoHeight property has been applied to the section. Getting this property can throw an exception if the height of sections was not calculated yet, for example if you access the RenderHeight of the report footer while the report header is being rendered.
When a sub-section grows or shrinks, its Height property does not change.
If you need to retrieve the actual height that will be used to rendering the sub-section (for example in the PrintSection event), use the RenderHeight property instead.
