How to get a group of toggle buttons to act like radio buttons in WPF?

I have a group of buttons that should act like toggle buttons, but also as radio buttons where only one button can be selected / pressed down at a current time. It also need to have a state where none of the buttons are selected / pressed down.

The behavior will be kind of like Photoshop toolbar, where zero or one of the tools are selected at any time!

Any idea how this can be implemented in WPF?

Solution 1:

This is easiest way in my opinion.

<RadioButton Style="{StaticResource {x:Type ToggleButton}}" />

Solution 2:

The easiest way is to style a ListBox to use ToggleButtons for its ItemTemplate

<Style TargetType="{x:Type ListBox}">
    <Setter Property="ListBox.ItemTemplate">
        <Setter.Value>
            <DataTemplate>
                <ToggleButton Content="{Binding}" 
                              IsChecked="{Binding IsSelected, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBoxItem}}}"
                />
            </DataTemplate>
        </Setter.Value>
    </Setter>
</Style>

Then you can use the SelectionMode property of the ListBox to handle SingleSelect vs MultiSelect.
