WPF Style Details

• Here are three ways to define a style:
  1. Define a style that will apply to all Button controls:

     <Style TargetType="Button">
         <Setter Property="FontSize" Value="18" />
         <Setter Property="FontFamily" Value="Verdana" />
     </Style>
     

     The Button controls need not reference the style.

  2. Define a style that uses a key. Each Button control that wants to use the style must reference the key.

     <Style x:Key="MyStyle" TargetType="Button">
         <Setter Property="FontSize" Value="18" />
         <Setter Property="FontFamily" Value="Verdana" />
     </Style>
     

     This style will apply to all buttons that reference the style named MyStyle. No control that is not a button can use the style.

  3. Define a style that uses a key, but that applies to all controls:

     <Style x:Key="MyStyle" TargetType="Control">
         <Setter Property="FontSize" Value="18" />
         <Setter Property="FontFamily" Value="Verdana" />
     </Style>
     

     This style will apply to all controls that reference the key.
