IsVisible Property

Summary

Indicates whether the drop shadow is visible and should be rendered.

Syntax

C++/CLI

public bool IsVisible { get; set; }

public:  
   property bool IsVisible 
   { 
      bool get() 
      void set(bool value) 
   }

Property Value

Debug.WriteLine("No drop shadow"); 
 
// Show the view drop shadow 
var dropShadow = _imageViewer.ViewDropShadow; 
dropShadow.IsVisible = true; 
_imageViewer.ViewDropShadow = dropShadow; 
Debug.WriteLine("View drop shadow"); 
dropShadow.IsVisible = false; 
_imageViewer.ViewDropShadow = dropShadow;
