如何MouseOver從動態集中獲取事件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>后面的代碼：fileDataList.Add(new FileData() { Name = System.IO.Path.GetFileNameWithoutExtension(filename), Date = File.GetLastWriteTime(filename), Type = System.IO.Path.GetExtension(filename), Size = GetFileSize(filename) });這是列表：public List<string> files = new List<string>();private ObservableCollection<FileData> fileDataList = new ObservableCollection<FileData>();

在ListView的資源中設置以下樣式：
<ListView.Resources>
<Style TargetType="ListViewItem">
<EventSetter Event="MouseEnter" Handler="ListViewItem_MouseEnter" />
<EventSetter Event="MouseLeave" Handler="ListViewItem_MouseLeave" />
</Style>
</ListView.Resources>
在后面的代碼中，使用以下代碼來確定當前懸停的項目。
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;
}
