Selected Property

Summary
Gets or sets the selected state for the disc.
Syntax
C#
C++/CLI
public DVDSourceSelectedState Selected { get; set; } 
public: 
property DVDSourceSelectedState Selected { 
   DVDSourceSelectedState get(); 
   void set (    DVDSourceSelectedState ); 
} 

Property Value

A DVDSourceSelectedState enumeration value representing the selected state for the disc.

Remarks

The selected states must be one of the DVDSourceSelectedState enumeration values. To select the entire disc, pass the DVDSourceSelectedState.Selected value. To remove the selection, pass the DVDSourceSelectedState.Unselected value. If the DVDSourceSelectedState.PartiallySelected value is passed, then the entire disc will be selected, and the property value will become DVDSourceSelectedState.Selected.

Note: that the ConvertCtrl.UseDVDSource and PlayCtrl.UseDVDSource properties should be set to true before specifying the DVD source image to force the player and the converter to use the DVDSource object when attempting to play or convert a DVD image.
