**两大部分：**

**第一部分：**

在xaml中写死的话可以如下:  
<esri:GraphicsLayer.MapTip>  
<Border BorderBrush="DarkGray" CornerRadius="13" BorderThickness="1" Margin="0,0,15,15">  
<Border.Effect>  
<DropShadowEffect ShadowDepth="10" BlurRadius="14" Direction="300" />  
</Border.Effect>  
<StackPanel>  
<Button x:Name="charttype" Width="10" Height="10"/>  
...........  
  
  
在后台代码中,需要动态生成MapTip  
MapTip tip = new MapTip();  
现在需要在MapTip中显示一个button  
怎么没有tip.child 这样的属性呢?  
  
问题:在后台代码中生成的MapTip如何放置button

如果連Maptip也完全由代碼生成的話，可以試試

1.  private void runTest()
2.  \{
3.  Grid grid = new Grid();
4.  Button button = new Button();
5.  button.Content = "test Button";
6.  button.Width = 100;
7.  button.Height = 20;
8.  button.Click += new RoutedEventHandler(button\_Click);
9.  grid.Children.Add(button);
10. graphicsLayer.MapTip = grid;
11. \}

*复制代码*

如果本來就有Maptip的話，可以在Maptip裏的第一層設像MouseEnter的事件  
比如說Maptip裏是Border的話，就加個

1.  private void Border\_MouseEnter(object sender, MouseEventArgs e)
2.  \{
3.  Border border = sender as Border;
4.  Button button = new Button();
5.  button.Width = 30;
6.  button.Height = 20;
7.  button.Click += new RoutedEventHandler(button\_Click);
8.  Grid grid = border.Child as Grid;
9.  grid.Children.Add(button);
10. \}

應該是可行的

**第二部分 ：**

//Grid grid = new Grid();

//Button button = new Button();

//button.Content = "test Button";

//button.Width = 100;

//button.Height = 20;

//button.Click += new RoutedEventHandler(button\_Click);

//grid.Children.Add(button);

//graphicsLayer.MapTip = grid;

//MapTip mymaptip = myLayoutRoot.Resources\["MyMapTip"\] as MapTip;  
//MapTip mymaptip2 = new MapTip();  
//mymaptip.GraphicsLayer = this.graphicsLayer;  
//mymaptip2.GraphicsLayer = this.graphicsLayer;  
//mymaptip.Title = "9999";  
//mymaptip2.Title = "9999";  
//this.graphicsLayer.MapTip = mymaptip;  
//this.graphicsLayer.MapTip = mymaptip2;

关键是 【】

MyBinding.Path = new PropertyPath("\[DEVICENAME\]");

Binding MyBinding = new Binding();  
MyBinding.Path = new PropertyPath("\[DEVICENAME\]");  
MyBinding.Mode = BindingMode.OneWay;  
//MyBinding.Source = graphicsLayer.Graphics;  
MapTip mymaptip = new MapTip();  
mymaptip.GraphicsLayer = this.graphicsLayer;  
mymaptip.AllowDrop = true;  
mymaptip.SetBinding(MapTip.TitleProperty, MyBinding);  
mymaptip.VerticalOffset = 100;  
mymaptip.HorizontalOffset = 100;  
this.graphicsLayer.MapTip = mymaptip;  
this.graphicsLayer.Refresh();
