   ByVal Editable As Boolean _
) As GdPictureStatus
public GdPictureStatus SetRegionEditable( 
   int RegionID,
   bool Editable
)
public function SetRegionEditable( 
    RegionID: Integer;
    Editable: Boolean
): GdPictureStatus; 
public function SetRegionEditable( 
   RegionID : int,
   Editable : boolean
) : GdPictureStatus;
public: GdPictureStatus SetRegionEditable( 
   int RegionID,
   bool Editable
) 
public:
GdPictureStatus SetRegionEditable( 
   int RegionID,
   bool Editable

Parameters

RegionID
A unique region identifier of the specified region. You can obtain this identifier using the GetRegionID method or when creating regions using the AddRegion(String,Double,Double,Double,Double,Color,RegionFillMode) method.
Editable
Set this parameter to true if you want to allow users to edit the specified region, otherwise set it to false.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.
Remarks
Be aware that if the required region does not exist, the method will fail.

Just to inform you, that all newly added regions are editable by default. You are allowed to change this behaviour for all regions at once by setting the RegionsAreEditable property.
