WPF气泡样式弹窗效果
页面设计需求,做了一个气泡形状的弹出框,效果如下:
设计思路如下:
1. 使用Path绘制气泡的尖尖,将这个放到顶层;
2. 在用border绘制长方形框,将这个放到底层,并且设置Margin值,使得Path图层和border看起来衔接在一起。
代码如下:

后台代码,很简单,就是控制pupup显示或隐藏
1 private void btnTestPopup1_Click(object sender, RoutedEventArgs e) 2 { 3 pop1.IsOpen = true; 4 } 5 private void btnOK1_Click(object sender, RoutedEventArgs e) 6 { 7 pop1.IsOpen = false; 8 } 9 private void btnCancel1_Click(object sender, RoutedEventArgs e)10 {11 pop1.IsOpen = false;12 }13 14 private void btnTestPopup2_Click(object sender, RoutedEventArgs e)15 {16 pop2.IsOpen = true;17 }18 private void btnOK2_Click(object sender, RoutedEventArgs e)19 {20 pop2.IsOpen = false;21 }22 private void btnCancel2_Click(object sender, RoutedEventArgs e)23 {24 pop2.IsOpen = false;25 }26 27 private void btnTestPopup3_Click(object sender, RoutedEventArgs e)28 {29 pop3.IsOpen = true;30 }31 private void btnOK3_Click(object sender, RoutedEventArgs e)32 {33 pop3.IsOpen = false;34 }35 private void btnCancel3_Click(object sender, RoutedEventArgs e)36 {37 pop3.IsOpen = false;38 }39 40 private void btnTestPopup4_Click(object sender, RoutedEventArgs e)41 {42 pop4.IsOpen = true;43 }44 private void btnOK4_Click(object sender, RoutedEventArgs e)45 {46 pop4.IsOpen = false;47 }48 private void btnCancel4_Click(object sender, RoutedEventArgs e)49 {50 pop4.IsOpen = false;51 }
