我的列表视图

    <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal" HorizontalAlignment="Left" VerticalAlignment="Center" >
                    <Label Name="lblChapterID" VerticalAlignment="Center"  Margin="0" Content="{Binding ChapterID}" Visibility="Hidden" />
                    <CheckBox Name="chkChapterTitle" VerticalAlignment="Center" Margin="0,0,0,0" Content="{Binding ChapterTittle}" Checked="chkChapterTitle_Checked" />
                </StackPanel>
            </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

推荐答案

您可以将 IsChecked 属性直接绑定到 ListViewItem 的 IsSelected.使用 RelativeSource 绑定到元素.

You can bind the IsChecked property directly to IsSelected of the ListViewItem. Use RelativeSource to bind to the element.

IsChecked="{Binding RelativeSource={RelativeSource AncestorType=ListViewItem},Path=IsSelected}"

现在如果你对ListView使用SelectionMode=Multiple，你可以直接使用SelectedItems拉取选中的项目.

Now if you use SelectionMode=Multiple for the ListView, you can pull the checked items directly using SelectedItems.

var chapters = new List<Chapter>();
foreach (var item in listViewChapter.SelectedItems)
    users.Add((Chapter)item);
