I have a list of objects that I need to represent as a list of buttons.
These buttons should normally act as a regular Button; when the checkbox is checked, they should work as ToggleButtons and remain pressed. But I also need them to be mutually exclusive, like a RadioButton (only one can only be toggled at any time).

I tried using a RadioButton as the template for my ItemsControl, but they are not mutually exclusive (I guess that they are not actually children of the same control).

So I thought to use a ToggleButton as the template, manually uncheck it if the checkbox is not checked, and manually handle the mutual exclusion.
However, I can't find a way to retrieve the toggle buttons for the other items in the list to uncheck them.

Here's my XAML:

<Window x:Class="WpfApp9.MainWindow"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d"

    Title="MainWindow" Height="450" Width="800">



<UniformGrid Rows="1">

    <UniformGrid.Resources>          

        <DataTemplate x:Key="template">

            <ToggleButton Name="Toggle"                              

                          Checked="ToggleButton_Checked"

                          Content="{Binding}"/>

        </DataTemplate>

    </UniformGrid.Resources>



    <ItemsControl Name="lst" ItemTemplate="{StaticResource template}" />



    <CheckBox Name="CheckToggle"

              HorizontalAlignment="Center"

              VerticalAlignment="Center">

        TOGGLE

    </CheckBox>

</UniformGrid>

</Window>

And this is my code-behind:

using System.Windows;

using System.Windows.Controls.Primitives;



namespace WpfApp9

{

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

            lst.ItemsSource = new { "foo", "bar", "baz" };

        }



        private void ToggleButton_Checked(object sender, RoutedEventArgs e)

        {

            var toggle = (ToggleButton)sender;



            // If the checkbox is not checked, release the button immediately

            if (CheckToggle.IsChecked != true)

                toggle.IsChecked = false;



            // now how do I uncheck the other ToggleButtons?

        }

    }

}

I ended up solving the problem above in a different way.
In the question I said that

I tried using a RadioButton as the template for my ItemsControl, but they are not mutually exclusive (I guess that they are not actually children of the same control)

but I didn't realize I could use the GroupName property to force them into the same group. At this point the template can be this:

    <DataTemplate x:Key="template">

        <RadioButton Checked="RadioButton_Checked"

                     GroupName="SomeGroupName"

                     Content="{Binding}"/>

    </DataTemplate>

And I get my mutually exclusive buttons without handling them manually.
