How to get selected items from listbox has checkboxes in WPF?

Question

This is the ListBox code:

Answer 1

It would probably be best to bind the CheckBox to the IsSelected property of the ListBoxItem, like so:

<DataTemplate>
    <CheckBox Content="{Binding .}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}, Path=IsSelected}" />
</DataTemplate>

Then you can get the checked/selected items from the ListBox.SelectedItems collection. You'd also have to set SelectionMode to Multiple.
