RegionsAreEditable Property (GdViewer)

In This Topic
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.

Syntax
'Declaration

 


Public Property RegionsAreEditable As Boolean
public bool RegionsAreEditable {get; set;}
public read-write property RegionsAreEditable: Boolean; 
public function get,set RegionsAreEditable : boolean
public: __property bool get_RegionsAreEditable();

public: __property void set_RegionsAreEditable( 

   bool value

);
public:

property bool RegionsAreEditable {

   bool get();

   void set (    bool value);

}

Property Value

The default value is true.
Remarks
Be aware that turning this property to false disables both region editing and the region selection as well.
