silverlight api string object border button

1、首先在SL项目中添加一个抽象类ContextMenu.cs文件，代码如下：


[csharp] view plain copy print ?
  1. using System;  
  2. using System.Net;  
  3. using System.Windows;  
  4. using System.Windows.Controls;  
  5. using System.Windows.Documents;  
  6. using System.Windows.Ink;  
  7. using System.Windows.Input;  
  8. using System.Windows.Media;  
  9. using System.Windows.Media.Animation;  
  10. using System.Windows.Shapes;  
  11. using System.Windows.Controls.Primitives;  
  12.   
  13. namespace MapClient  
  14. {  
  15.     public abstract class ContextMenu  
  16.     {  
  17.         private Point _location;  
  18.         private bool _isShowing;  
  19.         private Popup _popup;  
  20.         private Grid _grid;  
  21.         private Canvas _canvas;  
  22.         private FrameworkElement _content;  
  23.   
  24.         //初始化并显示弹出窗体.公共方法在显示菜单项时调用   
  25.         public void Show(Point location)  
  26.         {  
  27.             if (_isShowing)  
  28.                 throw new InvalidOperationException();  
  29.             _isShowing = true;  
  30.             _location = location;  
  31.             ConstructPopup();  
  32.             _popup.IsOpen = true;  
  33.         }  
  34.   
  35.         //关闭弹出窗体   
  36.         public void Close()  
  37.         {  
  38.             _isShowing = false;  
  39.             if (_popup != null)  
  40.             {  
  41.                 _popup.IsOpen = false;  
  42.             }  
  43.         }  
  44.   
  45.         //abstract function that the child class needs to implement to return the framework element that needs to be displayed in the popup window.   
  46.         protected abstract FrameworkElement GetContent();  
  47.   
  48.         //Default behavior for OnClickOutside() is to close the context menu when there is a mouse click event outside the context menu   
  49.         protected virtual void OnClickOutside()  
  50.         {  
  51.             Close();  
  52.         }  
  53.   
  54.         // 用Grid来布局，初始化弹出窗体   
  55.         //在Grid里面添加一个Canvas，用来监测菜单项外面的鼠标点击事件   
  56.         //   
  57.         // Add the Framework Element returned by GetContent() to the grid and position it at _location   
  58.         private void ConstructPopup()  
  59.         {  
  60.             if (_popup != null)  
  61.                 return;  
  62.             _popup = new Popup();  
  63.             _grid = new Grid();  
  64.             _popup.Child = _grid;  
  65.             _canvas = new Canvas();  
  66.             _canvas.MouseLeftButtonDown += (sender, args) => { OnClickOutside(); };  
  67.             _canvas.MouseRightButtonDown += (sender, args) => { args.Handled = true; OnClickOutside(); };  
  68.             _canvas.Background = new SolidColorBrush(Colors.Transparent);  
  69.             _grid.Children.Add(_canvas);  
  70.             _content = GetContent();  
  71.             _content.HorizontalAlignment = HorizontalAlignment.Left;  
  72.             _content.VerticalAlignment = VerticalAlignment.Top;  
  73.             _content.Margin = new Thickness(_location.X, _location.Y, 0, 0);  
  74.             _grid.Children.Add(_content);  
  75.             UpdateSize();  
  76.         }  
  77.   
  78.         /// <summary>   
  79.         /// 更新大小   
  80.         /// </summary>   
  81.         private void UpdateSize()  
  82.         {  
  83.             _grid.Width = Application.Current.Host.Content.ActualWidth;  
  84.             _grid.Height = Application.Current.Host.Content.ActualHeight;  
  85.             if (_canvas != null)  
  86.             {  
  87.                 _canvas.Width = _grid.Width;  
  88.                 _canvas.Height = _grid.Height;  
  89.             }  
  90.         }  
  91.     }  
  92. }  

2、再添加一个类用来实现左键点击弹出控件MapTips.cs文件，代码如下



[csharp] view plain copy print ?
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Net;  
  5. using System.Windows;  
  6. using System.Windows.Controls;  
  7. using System.Windows.Documents;  
  8. using System.Windows.Input;  
  9. using System.Windows.Media;  
  10. using System.Windows.Media.Animation;  
  11. using System.Windows.Shapes;  
  12. using System.Windows.Media.Effects;  
  13. using System.Windows.Media.Imaging;  
  14. using MapClient.ServiceReference1;  
  15.   
  16. namespace MapClient  
  17. {  
  18.     public class MapTips : ContextMenu  
  19.     {  
  20.         RichTextBox rtb;  
  21.         string placeName = string.Empty;  
  22.         string areaID = string.Empty;  
  23.         string year = string.Empty;  
  24.         string cycleID = string.Empty;  
  25.   
  26.         //弹出窗口中的显示文本控件   
  27.         TextBlock tb_title; //标题   
  28.         TextBlock tb_grade1; //苗情等级1   
  29.         TextBlock tb_grade2; //苗情等级2   
  30.         TextBlock tb_grade3; //苗情等级3   
  31.         TextBlock tb_grade4; //苗情等级4   
  32.   
  33.         TextBlock tb_percent1; //占比1   
  34.         TextBlock tb_percent2; //占比2   
  35.         TextBlock tb_percent3; //占比3   
  36.         TextBlock tb_percent4; //占比4   
  37.   
  38.         TextBlock tb_area1; //面积1   
  39.         TextBlock tb_area2; //面积2   
  40.         TextBlock tb_area3; //面积3   
  41.         TextBlock tb_area4; //面积4   
  42.   
  43.         HyperlinkButton hlb1; //超链接1   
  44.         HyperlinkButton hlb2; //超链接2   
  45.         HyperlinkButton hlb3; //超链接3   
  46.   
  47.         public MapTips(RichTextBox rtb, string name, string areaID, string year, string cycleID)  
  48.         {  
  49.             this.rtb = rtb;  
  50.             this.placeName = name;  
  51.             this.areaID = areaID;  
  52.             this.year = year;  
  53.             this.cycleID = cycleID;  
  54.         }  
  55.   
  56.   
  57.         //构造菜单按钮并返回一个FrameworkElement对象   
  58.         protected override FrameworkElement GetContent()  
  59.         {  
  60.             Border border = new Border() { BorderBrush = new SolidColorBrush(Color.FromArgb(255, 167, 171, 176)), BorderThickness = new Thickness(1), Background = new SolidColorBrush(Colors.White) };  
  61.             border.Effect = new DropShadowEffect() { BlurRadius = 3, Color = Color.FromArgb(255, 230, 227, 236) };  
  62.             Grid grid = new Grid() { Margin = new Thickness(1) };  
  63.             //九行   
  64.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });  
  65.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });  
  66.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });  
  67.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });  
  68.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });

  72.             grid.RowDeFinitions.Add(new RowDeFinition() { Height = new GridLength(30) });  
  73.             //三列   
  74.             grid.ColumnDeFinitions.Add(new ColumnDeFinition() { Width = new GridLength(80) });

  77.             //标题第一列   
  78.             tb_title = new TextBlock() { FontSize = 14, HorizontalAlignment = HorizontalAlignment.Center, VerticalAlignment = VerticalAlignment.Center };

  187.         }  
  188.   
  189.         void client_GetCommentInfoCompleted(object sender, GetCommentInfoCompletedEventArgs e)  
  190.         {  
  191.             //设置值   
  192.             tb_title.Text = result.Split(',')[0].Split(':')[1];  
  193.             //苗情评价分析

  218.   
  219.         }  
  220.     }  
  221. }  


3、添加一个鼠标右键弹出的快捷菜单控件RTBContextMenu .cs文件，代码如下：


[csharp] view plain copy print ?
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Net;  
  5. using System.Windows;  
  6. using System.Windows.Controls;  
  7. using System.Windows.Documents;  
  8. using System.Windows.Input;  
  9. using System.Windows.Media;  
  10. using System.Windows.Media.Animation;  
  11. using System.Windows.Shapes;  
  12. using System.Windows.Media.Effects;  
  13. using System.Windows.Media.Imaging;  
  14.   
  15. namespace MapClient  
  16. {  
  17.     public class RTBContextMenu : ContextMenu  
  18.     {  
  19.         RichTextBox rtb;  
  20.         string placeName = string.Empty;  
  21.   
  22.         public RTBContextMenu(RichTextBox rtb, string name)  
  23.         {  
  24.             this.rtb = rtb;  
  25.             this.placeName = name;  
  26.         }
