Question

有多个图钉。如果我们点击图钉显示另一个带有动态数据模板的图钉，其中包含图像和windows phone c＃中的两个文本块控件。请帮忙。

<my:Map HorizontalAlignment="Stretch" Name="ServiceMap" VerticalAlignment="Stretch"    MapPan="ServiceMap_MapPan"> 
<my:MapItemsControl x:Name="mapControl" Margin="0,0,0,44" /></my:Map>

<phone:PhoneApplicationPage.Resources>
<ControlTemplate x:Key="PushpinControlTemplate1" TargetType="my:Pushpin">
<Grid Name="contentGrid" Width="40"  Height="75" HorizontalAlignment="Center"  VerticalAlignment="Center">
<Image x:Name="Layer_1" Height="75" Source="/Images/CurrentLoc.png"/>
</Grid>
</ControlTemplate>
<ControlTemplate x:Key="PushPinTemplate2" TargetType="my:Pushpin">
<Grid Name="contentGrid" HorizontalAlignment="Center" VerticalAlignment="Center" Background="Silver" Opacity="0.7">
<Image Name="imgPin" Source="/Images/maponinemarker.png" Height="50" Width="50">      </Image>
<TextBlock Text="{Binding Id}" Margin="6,0" FontSize="24" Name="txtId"></TextBlock>
<TextBlock Text="{Binding Name}" Margin="50,50,50,50" FontSize="24"></TextBlock>
</Grid>
</ControlTemplate>

    Pushpin pin = new Pushpin();             
    pin.Location = e.Position.Location;
    pin.Template = (ControlTemplate)(this.Resources["PushpinControlTemplate1"]);
    mapControl.Items.Add(pin);
    pin.Tap+=(s,tapEve)=>
    {
    Pushpin contentPin = new Pushpin();
    contentPin.Location = e.Position.Location;
    contentPin.Template = (ControlTemplate)(this.Resources["PushpinControlTemplate2"]);
    MapView.Children.Add(contentPin);
    };

第一个图钉正确显示。当点击第一个图钉时，它如何使用PushpinControlTemplate2的模板显示第二个图钉。如果我们将值分配给模板，那么它就会被分配

点击Bingmap上的图钉显示另一个图钉WP7
