WPF MVVM: How to disable clicked button and enable all other buttons?

Question

I have a group of buttons that are enabled whenever one of the buttons is clicked and the clicked one is disabled.

<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>
<Button DockPanel.Dock="Top" Style="{StaticResource BigGrayButton}" Command="{Binding Path=NavigatePage}" IsEnabled="{Binding Path=EnableButton}"/>

The problem is using the above code result in disabling all buttons when setting EnableButton to false after executing the command.

As I said, why not try RadioButton ?

If you only want to achieve this "feature", this is too easy - even don't need involve MVVM

<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <StackPanel.Resources>
        <SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
        <SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>
        <SolidColorBrush x:Key="Button.MouseOver.Background" Color="#FFBEE6FD"/>
        <SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>
        <SolidColorBrush x:Key="Button.Pressed.Background" Color="#FFC4E5F6"/>
        <SolidColorBrush x:Key="Button.Pressed.Border" Color="#FF2C628B"/>
        <SolidColorBrush x:Key="Button.Disabled.Background" Color="#FFF4F4F4"/>

Then you can setting CommandParameter for each button to tell the backend code which button was pressed.

You don't need to write any complicated logic to implement this feature. Why not try it?
