WPF自定义控件和样式之自定义按钮（Button）

2.4 文字按钮和2.3中的图标文字按钮样式差不多，只需要把Image控件去掉就行。

三、复用性高的按钮

要想实现复用性高的按钮，就必须新建自定义控件。下面这个实例通过自定义控件实现上述所有效果，并且可以随意更改风格。

首先在项目中右键-添加-新建项-自定义控件。

新建自定义控件之后，添加依赖属性。代码如下：

public class ButtonEx : Button
 {
  static ButtonEx()
  {
   DefaultStyleKeyProperty.OverrideMetadata(typeof(ButtonEx), new FrameworkPropertyMetadata(typeof(ButtonEx)));
  }


  public ButtonType ButtonType
  {
   get { return (ButtonType)GetValue(ButtonTypeProperty); }
   set { SetValue(ButtonTypeProperty, value); }
  }

  public static readonly DependencyProperty ButtonTypeProperty =
   DependencyProperty.Register("ButtonType", typeof(ButtonType), typeof(ButtonEx), new PropertyMetadata(ButtonType.Normal));


  public ImageSource Icon
  {
   get { return (ImageSource)GetValue(IconProperty); }
   set { SetValue(IconProperty, value); }
  }

  public static readonly DependencyProperty IconProperty =
   DependencyProperty.Register("Icon", typeof(ImageSource), typeof(ButtonEx), new PropertyMetadata(null));


  public CornerRadius CornerRadius
  {
   get { return (CornerRadius)GetValue(CornerRadiusProperty); }
   set { SetValue(CornerRadiusProperty, value); }
  }

  public static readonly DependencyProperty CornerRadiusProperty =
   DependencyProperty.Register("CornerRadius", typeof(CornerRadius), typeof(ButtonEx), new PropertyMetadata(new CornerRadius(0)));


  public Brush MouseOverForeground
  {
   get { return (Brush)GetValue(MouseOverForegroundProperty); }
   set { SetValue(MouseOverForegroundProperty, value); }
  }

  public static readonly DependencyProperty MouseOverForegroundProperty =
   DependencyProperty.Register("MouseOverForeground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


  public Brush MousePressedForeground
  {
   get { return (Brush)GetValue(MousePressedForegroundProperty); }
   set { SetValue(MousePressedForegroundProperty, value); }
  }

  public static readonly DependencyProperty MousePressedForegroundProperty =
   DependencyProperty.Register("MousePressedForeground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


  public Brush MouseOverBorderbrush
  {
   get { return (Brush)GetValue(MouseOverBorderbrushProperty); }
   set { SetValue(MouseOverBorderbrushProperty, value); }
  }

  public static readonly DependencyProperty MouseOverBorderbrushProperty =
   DependencyProperty.Register("MouseOverBorderbrush", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


  public Brush MouseOverBackground
  {
   get { return (Brush)GetValue(MouseOverBackgroundProperty); }
   set { SetValue(MouseOverBackgroundProperty, value); }
  }

  public static readonly DependencyProperty MouseOverBackgroundProperty =
   DependencyProperty.Register("MouseOverBackground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());


  public Brush MousePressedBackground
  {
   get { return (Brush)GetValue(MousePressedBackgroundProperty); }
   set { SetValue(MousePressedBackgroundProperty, value); }
  }

  public static readonly DependencyProperty MousePressedBackgroundProperty =
   DependencyProperty.Register("MousePressedBackground", typeof(Brush), typeof(ButtonEx), new PropertyMetadata());
 }

 public enum ButtonType
 {
  Normal,
  Icon,
  Text,
  IconText
 }
