WPF ListView:附加双击(在项目上)事件 [英] WPF ListView: Attaching a double-click (on an item) event

问题描述

我有以下 ListView:

<ListView Name="TrackListView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Title" Width="100" 
                            HeaderTemplate="{StaticResource BlueHeader}" 
                            DisplayMemberBinding="{Binding Name}"/>

            <GridViewColumn Header="Artist" Width="100"  
                            HeaderTemplate="{StaticResource BlueHeader}"  
                            DisplayMemberBinding="{Binding Album.Artist.Name}" />
        </GridView>
    </ListView.View>
</ListView>

如何将事件附加到每个绑定的项目上，该事件将在双击项目时触发?

How can I attach an event to every bound item that will fire on double-clicking the item?

推荐答案

从这里找到解决方案:http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/3d0eaa54-09a9-4c51-8677-8e7905

XAML:

<UserControl.Resources>
    <Style x:Key="itemstyle" TargetType="{x:Type ListViewItem}">
        <EventSetter Event="MouseDoubleClick" Handler="HandleDoubleClick" />
    </Style>
</UserControl.Resources>

<ListView Name="TrackListView" ItemContainerStyle="{StaticResource itemstyle}">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Title" Width="100" HeaderTemplate="{StaticResource BlueHeader}" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn Header="Artist" Width="100" HeaderTemplate="{StaticResource BlueHeader}" DisplayMemberBinding="{Binding Album.Artist.Name}" />
        </GridView>
    </ListView.View>
</ListView>

C#:

protected void HandleDoubleClick(object sender, MouseButtonEventArgs e)
{
    var track = ((ListViewItem) sender).Content as Track; //Casting back to the binded Track
}
