Question

我即将在我的地图上的每个图钉中添加模板<Button>控件，以便与用户点击（呃，触摸）图钉进行交互。这是使用图钉的正确方法吗？我不想处理MouseDown和MouseUp并重新发明所有东西（没有人应该）。

我只需要确认。

Answer 1

MouseLeftBUttonUp？我只有模拟器，它适用于我的自定义图钉：

<Maps:MapItemsControl ItemsSource="{Binding Stores}">
                <Maps:MapItemsControl.ItemTemplate>
                    <DataTemplate>
                        <Maps:Pushpin Location="{Binding Location}" MouseLeftButtonUp="Pushpin_MouseLeftButtonUp">
                            <Maps:Pushpin.Template>
                                <ControlTemplate TargetType="Maps:Pushpin">
                                    <Border BorderBrush="Black" BorderThickness="1" Background="MintCream" Width="32" Height="32" HorizontalAlignment="Center" VerticalAlignment="Center">
                                        <TextBlock Text="{Binding Store.Address}" FontWeight="Bold" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                    </Border>
                                </ControlTemplate>
                            </Maps:Pushpin.Template>
                        </Maps:Pushpin>
                    </DataTemplate>
                </Maps:MapItemsControl.ItemTemplate>
            </Maps:MapItemsControl>

编辑：获得真实设备后，我已经测试了我的应用程序，我可以确认MouseLeftBUttonUp是一个坏主意（并不是微软在Performance tips中推荐的）

相反，你应该使用操纵事件：

<Maps:MapItemsControl ItemsSource="{Binding Stores}">
<Maps:MapItemsControl.ItemTemplate>
    <DataTemplate>
        <Maps:Pushpin Location="{Binding Location}" ManipulationStarted="Pushpin_ManipulationStarted">
            <Maps:Pushpin.Template>
                <ControlTemplate TargetType="Maps:Pushpin">
                    <Image Width="48" Height="48" Source="{Binding InventoryIcon}" />
                </ControlTemplate>
            </Maps:Pushpin.Template>
        </Maps:Pushpin>
    </DataTemplate>
</Maps:MapItemsControl.ItemTemplate>
</Maps:MapItemsControl>

为什么不在MapItemsControl.ItemTemplate中添加Invisible样式按钮并使用单击按钮。

如果您只想点击/点按每个图钉，请将MouseLeftButtonUp事件添加到您创建的每个图钉中。例如：

Microsoft.Phone.Controls.Maps.Pushpin pp = null;
System.Device.Location.GeoCoordinate loc = null;

pp = new Microsoft.Phone.Controls.Maps.Pushpin();
loc = new System.Device.Location.GeoCoordinate([Latitude], [Longitude]);

pp.Location = loc;
pp.Content = "Some Content";
pp.MouseLeftButtonUp += new MouseButtonEventHandler(Pushpin_MouseLeftButtonUp);

然后你添加

void Pushpin_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
     Microsoft.Phone.Controls.Maps.Pushpin tempPP = new Microsoft.Phone.Controls.Maps.Pushpin();

     tempPP = (Microsoft.Phone.Controls.Maps.Pushpin)sender;

     // you can check the tempPP.Content property

}
