    RegionEditedByUser Event (GdViewer)
    In This Topic
    This event is raised when a highlighted region has been moved or resized, which actually means edited, by a user using the mouse.

    Please check the corresponded GdViewer.RegionEditedByUserEventHandler for given parameters.

    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 AddRegion(String,Int32,Int32,Int32,Int32,ForegroundMixMode,Int32) or AddRegionInches(String,Single,Single,Single,Single,ForegroundMixMode,Int32) methods.
