Silverlight: Changing color of all buttons in the application

I am new to silverlight. I would li开发者_如何学运维ke to know how to change the color all the buttons in my application to gray. Is there any way to define a user control that inherits from Button class and then use that globally as done in windows forms?

Try this

inside you App.XAML add a style for button

 <Application.Resources>
        <Style TargetType="Button">
            <Setter Property="Background" Value="Gray"/>
        </Style>
 </Application.Resources>

Now when you will declare a button in let's say in MainWindow, its background color will be Gray

 <Button Content="Sample Button"/>

Create a file themes/generic.xaml and put your button style there:

<Style TargetType="Button">
  <Setter Property="Background" Value="Gray"/>
</Style>
