如何从其子控件访问 ListViewItem?
How can I get access to ListViewItem from its child control?
我有一些来自集合的 ListViewItem
,我创建了一个 DataTemplate
,这样每个 ListViewItem
都有一个 Button
作为子控件:
<Window.Resources>
<DataTemplate x:Key="ItemTemplate_AwesomeTemplate">
<StackPanel Orientation="Vertical" VerticalAlignment="Stretch">
<Button Content="Awesome Button" Click="Awesome_Button_Click" HorizontalContentAlignment="Center" VerticalAlignment="Bottom" FontWeight="Bold" Foreground="Black"/>
</StackPanel>
</DataTemplate>
</Window.Resources>
<ListView x:Name="AwesomeListView" HorizontalAlignment="Left" Height="577" VerticalAlignment="Top" Width="934" ScrollViewer.HorizontalScrollBarVisibility="Visible" Foreground="Black" Margin="10,10,0,0">
<ListView.View>
<GridView>
<GridViewColumn Header="AwesomeHeader" Width="250" CellTemplate="{StaticResource ItemTemplate_AwesomeTemplate}"/>
</GridView>
</ListView.View>
</ListView>
当我单击某个 Button
时,有没有办法更改包含单击的 Button
的 ListViewItem
的 IsSelected
属性?
要更改包含单击的 Button
的 ListViewItem
属性,您应该使用 DataContext
找到这样的项目:
private void Awesome_Button_Click(object sender, RoutedEventArgs e)
{
var item = (sender as Button).DataContext;
int index = AwesomeListView.Items.IndexOf(item);//find the index of the item that contains the clicked button
AwesomeListView.SelectedItem = AwesomeListView.Items[index];//set the AwesomeListView's SelectedItem to item that contains the clicked button
}
