How to get Checked rows values of a ListView in WPF

Question

I have a ListView in WPF application with a CheckBox.

I want to save the values of all Checked rows in a WPF List ...

How can I achieve this?

My ListView

<ListView x:Name="listViewChapter" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderThickness="0" SelectionMode="Single" Height="100" Margin="22,234,17,28" Grid.Row="1">
    <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>

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}"

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);

You should consider using the MVVM pattern for your WPF application, and if you're going to use MVVM then you'll want an MVVM framework.

Then, it would be a case of creating a type that represents your databound object (e.g Book), then having a collection of this type on your view model (e.g. ObservableCollection<Book> Books).

You would then bind a Selected boolean property for example on your Book type to the CheckBox's IsChecked property in your ListBox ItemTemplate.

<CheckBox IsChecked="{Binding Selected}" />

You may not want to polute your domain object (Book) with properties purely used for the UI (Selected), so you could create a BookViewModel type which augments the Book type and reshapes the object purely for the purposes of the view.
