How to highlight the clicked button on the user interface in window phone 7

I am developing window phone 7 application in C#. I am new to the silverlight. I have more than one buttons in my application for different purposes. I am performing the click operation on one of the button amongst these buttons. Now I want to show the selected button to the user on the user interface screen. So I want to highlight that selected button so that the user interface will show that particular clicked button in a different manner than the other button on the screen. Previously I have tried for the following scenario

It seems like you're looking for the RadioButton functionality on a couple of Buttons. In that case, you can just re-template a RadioButton with the default Button-Template and add the VisualState for Checked. This example will make the Background turn Red for the latest Clicked Button, I hope that's what you're after

<StackPanel>
    <RadioButton Style="{StaticResource RadioButtonStyle1}"
                 GroupName="buttonGroup"
                 HorizontalContentAlignment="Center"
                 Content="Some Button"/>
    <RadioButton Style="{StaticResource RadioButtonStyle1}"
                 GroupName="buttonGroup"
                 HorizontalContentAlignment="Center"
                 Content="Some Button 2"/>
</StackPanel>

And the RadioButtonStyle1

<Style x:Key="RadioButtonStyle1" TargetType="RadioButton">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
    <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
    <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
    <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
    <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
    <Setter Property="Padding" Value="10,3,10,5"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="RadioButton">
                <Grid Background="Transparent">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CheckStates">
                            <VisualState x:Name="Checked">
                                <Storyboard>
