Step1:Trigger
 事件响应方式1——trigger

            <Image  Stretch="UniformToFill" >
                <Image.Style>
                    <Style>
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=rb1,Path=IsChecked,Mode=OneWay}" Value="True">

                            </DataTrigger>
                            <DataTrigger Binding="{Binding ElementName=rb2,Path=IsChecked,Mode=OneWay}" Value="True">

                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </Image.Style>
            </Image>

Step1:C#处理函数
Page2.xaml

                <StackPanel Orientation="Horizontal" >
                    <RadioButton x:Name="rb1" Checked="RbChecked" Margin="2 2" Style="{StaticResource MaterialDesignTabRadioButton}" Content="选项卡1" FontSize="15" VerticalAlignment="Center"/>
                    <RadioButton x:Name="rb2" Checked="RbChecked"  Margin="2 2" Style="{StaticResource MaterialDesignTabRadioButton}" Content="选项卡2" FontSize="15" VerticalAlignment="Center"/>

                </StackPanel>

Page.cs

            RadioButton rb = sender as RadioButton;
            MessageBox.Show("RadioButton "+ rb.Name +" is checked!");
