WPF Checked ListBox

WPF currently does not have a checked list box out of the box so you’ll need to roll your own. Unfortunately most of the examples that come up on Google involve creating a usercontrol and writing some code.

Here’s one quick way that does not not involve writing any additional code.

Step 1: Start off by creating a class that will represent each checked list item in the list box. Obviously if you already have your data item all you need to ensure is that it has a boolean property to store the Checked/Unchecked flag.

public class CheckedListItem
    public int Id { get; set; }
    public string Name { get; set; }
    public bool IsChecked { get; set; }


Step 2: Create the list item that will be bound to the list box. I called my list AvailablePresentationObjects.

public List<CheckedListItem> AvailablePresentationObjects;

Step 3: The last step is to create the actual checked list box. I created a list box and used the HierarchicalDataTemplate to hold the CheckBox. The Name and the IsChecked property are then bound to the checkbox.

<ListBox ItemsSource="{Binding AvailablePresentationObjects}" >
            <CheckBox Content="{Binding Name}" IsChecked="{Binding IsChecked}"/>

And walla!


Now the IsChecked property will reflect the value in the UI and vice versa. If you need real-time notification when someone checks/unchecks then you simply need to raise the PropertyChanged event in the CheckedListItem class.
