Selected Property (DVDSource)






Leadtools.Multimedia Namespace > DVDSource Class : Selected Property
Gets or sets the selected state for the disc.
Syntax
public DVDSourceSelectedState Selected {get; set;}
'Declaration
 

Public Property Selected As DVDSourceSelectedState
'Usage
 

Dim instance As DVDSource
Dim value As DVDSourceSelectedState
 
instance.Selected = value
 
value = instance.Selected
public:
property DVDSourceSelectedState Selected {
   DVDSourceSelectedState get();
   void set (    DVDSourceSelectedState value);
}

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.
