WPF 从动态集 ListViewItem 中获取 MouseHover 事件

Question

如何MouseOver从动态集中获取事件ListViewItems？XAML：<ListView Name="ListView" x:FieldModifier="public" ItemsSource="{Binding FileDataList}" Grid.Row="3" Grid.Column="3" Grid.ColumnSpan="8" Grid.RowSpan="12">           <ListView.View>        <GridView>            <GridViewColumn Header="Filename" DisplayMemberBinding="{Binding Name}" Width="Auto"/>            <GridViewColumn Header="Change date" DisplayMemberBinding="{Binding Date}" Width="Auto"/>            <GridViewColumn Header="Type" DisplayMemberBinding="{Binding Type}" Width="Auto"/>            <GridViewColumn Header="Size" DisplayMemberBinding="{Binding Size}" Width="Auto"/>        </GridView>    </ListView.View>            </ListView>后面的代码：fileDataList.Add(new FileData() { Name = System.IO.Path.GetFileNameWithoutExtension(filename), Date = File.GetLastWriteTime(filename), Type = System.IO.Path.GetExtension(filename), Size = GetFileSize(filename) });这是列表：public List<string> files = new List<string>();private ObservableCollection<FileData> fileDataList = new ObservableCollection<FileData>();

Answer 1

在ListView的资源中设置以下样式：

 <ListView.Resources>

       <Style TargetType="ListViewItem">

          <EventSetter Event="MouseEnter" Handler="ListViewItem_MouseEnter" />

          <EventSetter Event="MouseLeave" Handler="ListViewItem_MouseLeave" />

       </Style>

 </ListView.Resources>

在后面的代码中，使用以下代码来确定当前悬停的项目。

private ListViewItem _currentItem = null;

private void ListViewItem_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)

{

    var item = sender as ListViewItem;

    if (!Equals(_currentItem, item))

    {

        _currentItem = item;

        // code to update window 

    }

}

private void ListViewItem_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)

{

    _currentItem = null;

}
