Question

Is there a way in XAML to set a style that will apply to all controls? For example below I would like to put a margin on all my controls. I can add a style for each type by change the TargetType to Button, CheckBox, etc. Instead, I would like to set it up like I have below where I set the style on all types that inherit from Control:

<UserControl x:Class='MyPanel'     xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'     xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'     xmlns:sys='clr-namespace:System;assembly=mscorlib'     Height='300' Width='300'>     <UserControl.Resources>         <Style TargetType='Control'>             <Setter Property='Margin' Value='3'/>         </Style> </UserControl.Resources>     <StackPanel>         <Button>My Button</Button>         <CheckBox>My Checkbox</CheckBox>     </StackPanel> </UserControl>

There is no way to do this. However, you can define a base style and inherit from that:

<Style x:Key='BaseStyle'>     <Setter Property='FrameworkElement.Margin' Value='3'/> </Style>  <Style TargetType='Button' BasedOn='{StaticResource BaseStyle}'> </Style>  <Style TargetType='TextBox' BasedOn='{StaticResource BaseStyle}'> </Style>
