RegionsAreEditable Property (GdViewer)
Determines if highlighted regions can be selected or edited by a user.
Highlighted regions for currently displayed document are identified and created when searching text, for example using the SearchText(String,Int32,Boolean) method or the second similar overloaded method as well. You can also define highlighted regions directly using the AddRegion(String,Double,Double,Double,Double,Color,RegionFillMode) method.
