microsoft-metro - 如何使用 C# 和 Xml 在 Bing 地图 Metro 应用程序中的图钉上添加鼠标单击事件？

Question

我在 bing 地图上有多个动态图钉。我想在这些图钉上添加鼠标点击事件。告诉我我该怎么做。我正在使用 C# 和 XML 在 Windows 商店应用程序中工作。

当您以编程方式添加图钉时，将公共事件处理程序添加Tapped到每个图钉。当图钉被点击时，它将被调用，并且sender您可以从对象中区分每个图钉并做任何您喜欢的事情。

//Suppose I have PushpinsCollection which is list of MyPushpin class. PushpinsCollection is generated dynamically
public class MyPushpin
{
    public int PinID { get; set; }
    public Pushpin Pin { get; set; }
    public Location PinLocation { get; set; }
}

//run foreach loop do add event hanlder and add to map
//Here MyMap is Bing Map control
foreach(var pushpin in PushpinsCollection)
{
    var _pin = pushpin.Pin;
    _pin.Tapped += Pushpin_Tapped
    MapLayer.SetPosition(_pin, PinLocation);
    MyMap.Children.Add(_pin);
}

private void Pushpin_Tapped(object sender, TappedRoutedEventArgs e)
{
    var TappedPin = (Pushpin)sender;
    //TODO: do whatever opetraion you want to with TappedPin
}
