WPF自定义listview的listviewitem模板，绑定到集合

Question

wpf listview 如何得到按钮所在行?
listview 有两列.一列是内容.一列是删除按钮.
点删除按钮时就删除这个按钮所在的行.
 <ListView>            <ListView.ItemTemplate>                <DataTemplate>                    <WrapPanel>                        <TextBlock Text="{Binding Path=w2}" MinWidth="180" />                        <Button Content="删除" MinWidth="80" Click="Button_Click" />                    </WrapPanel>                </DataTemplate>            </ListView.ItemTemplate> </ListView>
