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 (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.
