In WinUI 3 and C#, how do I bind to the auto-generated CheckBox controls from a ListView that has the property selectionMode="Multiple"?

To bind to the auto-generated CheckBox controls from a ListView that has the property selectionMode="Multiple" in WinUI 3 and C#, you can use the ItemContainerStyle property of the ListView control. The ItemContainerStyle property allows you to specify the style to apply to the container of each item in the ListView.

You can define a style for the ListViewItemPresenter control and set the IsHitTestVisible property to false to disable selection on the ListViewItemPresenter. Then, you can add a CheckBox control to the ListViewItemPresenter and bind its IsChecked property to a property in your data model.

Here's an example of how to bind to the auto-generated CheckBox controls in a ListView:

xmlCopy code
<ListView ItemsSource="{Binding Items}" SelectionMode="Multiple">

    <ListView.ItemContainerStyle>

        <Style TargetType="ListViewItem">

            <Setter Property="IsHitTestVisible" Value="False" />

            <Setter Property="HorizontalContentAlignment" Value="Stretch" />

            <Setter Property="ContentTemplate">

                <Setter.Value>

                    <DataTemplate>

                        <StackPanel Orientation="Horizontal">

                            <CheckBox IsChecked="{Binding IsSelected}" Margin="5" />

                            <TextBlock Text="{Binding Name}" />

                        </StackPanel>

                    </DataTemplate>

                </Setter.Value>

            </Setter>

        </Style>

    </ListView.ItemContainerStyle>

</ListView>

In this example, the IsChecked property of the CheckBox control is bound to the IsSelected property of the data model. When the CheckBox is checked or unchecked, the IsSelected property of the corresponding data item is updated.
