Syntax

C#
C++/CLI
C++
public virtual RasterViewerInteractiveMode InteractiveMode { get; set; } 
public: 
virtual property RasterViewerInteractiveMode InteractiveMode { 
   RasterViewerInteractiveMode get(); 
   void set (    RasterViewerInteractiveMode ); 
} 
public:  
   virtual property RasterViewerInteractiveMode^ InteractiveMode 
   { 
      RasterViewerInteractiveMode^ get() 
      void set(RasterViewerInteractiveMode^ value) 
   } 

Property Value

The value which controls the user interaction with the control's display.

Remarks

By default, the mouse left button starts and controls the interactive mode. To change this behavior, refer to InteractiveModeMouseButton.

You can change the mouse cursor associated with a particular interative mode with the SetInteractiveModeCursor method.

Example

This sample changes between interactive modes -- from none, to pan, to magnifying glass, to Region, and back to none.
