Disable button when clicked and make other buttons enabled

i have three buttons in my wpf window what is the best way to disable button when clicked and make other two button enabled

<Button Name="initialzeButton"
                    Width="50"
                    Height="25"
                    Margin="460,0,0,0"
                    HorizontalAlignment="Left"
                    VerticalAlignment="Center"
                    Click="initialzeButton_Click"
                    Content="Start"
                    Cursor="Hand" />
            <Button Name="uninitialzeButton"
                    Width="50"
                    Height="25"
                    Margin="0,0,64,0"
                    HorizontalAlignment="Right"
                    VerticalAlignment="Center"
                    Click="uninitialzeButton_Click"
                    Content="Stop"
                    Cursor="Hand" />
            <Button Name="loadButton"
                    Width="50"
                    Height="25"
                    Margin="0,0,9,0"
                    HorizontalAlignment="Right"
                    VerticalAlignment="Center"
                    Click="loadButton_Click"
                    Content="Load"
                    Cursor="Hand" />

now i use this way in each button :( 

      private void uninitialzeButton_Click(object sender, RoutedEventArgs e)
      {

            this.uninitialzeButton.IsEnabled = false;
            if (!this.initialzeButton.IsEnabled)
            {
                 this.initialzeButton.IsEnabled = true;
            }
            if (!this.loadButton.IsEnabled)
            {
                 this.loadButton.IsEnabled = true;
            }


      }

For a pure XAML solution wrap them in a style stripped ListBox and tie the click to selection, and selection to disabled state.

What is your definition of 'best way'? Is it quick and few lines of code or elegant or..

Several ways come into my mind:
- Use MVVM Light: 1 relaycommand for the three buttons, 3 dependency objects (properties in the viewmodel) for isEnabled which will all be set to false, only set isEnabled to true for the button clicked (which could be sent as a parameter in the relaycommand).
- Use booleanconverters/booleaninverterconverters on the isEnabled property.
- Restyle radiobutton to look like a button, replace the three buttons with a radiobutton group. When one radiobutton is selected, the other ones will be deselected, style them as disabled. Prevent deselected items from being clicked.

Regards,

Michel

you can do somthing like this on page load - 

PostBackOptions postBackOptions = new PostBackOptions(Button1);
            Button1.OnClientClick = "this.disabled=true;";
            Button1.OnClientClick += ClientScript.GetPostBackEventReference(postBackOptions);
