在后台代码中设定控件的Visibility

在不同情况下，显示不同的控件。

Case1：ToggleButton显示，Grid的Visibility通过ToggleButton的IsChecked属性绑定；

Case2：ToggleButton隐藏，Grid显示。

 

通过类型判断进入处理部分：

 1 public HelloWindow(WinType type)

 2 {

 3     winType = type;

 4 

 5     InitializeComponent();

 6 

 7     if (winType == WinType.Case1)

 8     {

 9         myToggleButton.Visibility = System.Windows.Visibility.Collapsed;

10         myGrid.Visibility = System.Windows.Visibility.Visible;

11     }

12     else if (winType == WinType.Case2)

13     {

14         myToggleButton.Visibility = System.Windows.Visibility.Visible;

15         Binding binding = new Binding()

16         {

17             ElementName = "myToggleButton",

18             Path = new PropertyPath("IsChecked"),

19             Converter = (BooleanToVisibilityConverter)this.FindResource("b2v"),

20             Mode = BindingMode.OneWay

21         };

22         myGrid.SetBinding(Grid.VisibilityProperty, binding);

23         // 或者使用静态方法

24         // BindingOperations.SetBinding(myGrid, Grid.WidthProperty, binding);

25     }

26 }
