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.ItemTemplate>
            <DataTemplate>

                    <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>

Answer 1

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);

Answer 2

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 (eg Book ), then having a collection of this type on your view model (eg 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.
