When we define a Style in an XAML resource section & set it’s TargetType

  • 0

When we define a Style in an XAML resource section & set it’s TargetType property to a specific control type then we do not need to set Style property to control of that type. e.g.

<Window.Resources>
        <Style TargetType="Button">
            <Setter Property="Content" Value="Style set for all buttons"/>
            <Setter Property="Background" Value="Gray"/>
        </Style>
    </Window.Resources>
    <Grid>
        <Button Height="27" HorizontalAlignment="Left" Margin="119,56,0,0" Name="button1" VerticalAlignment="Top" Width="140" />
        <Button Style="{x:Null}" Content="No Style" Height="27" HorizontalAlignment="Left" Margin="212,121,0,0" Name="button2" VerticalAlignment="Top" Width="141" />
        <Button  Content="Button" Height="25" HorizontalAlignment="Left" Margin="296,183,0,0" Name="button3" VerticalAlignment="Top" Width="158" />
    </Grid>

But when we want to define a style for all controls in a window then we need to add Style property to each control to have that defined style. e.g.

<Window.Resources>
        <Style x:Key="Style1" TargetType="Control">
            <Setter Property="Control.Background" Value="Gray"/>
        </Style>
    </Window.Resources>
    <Grid>
        <Button Style="{StaticResource Style1}" Content="Button" Height="23" HorizontalAlignment="Left" Margin="67,52,0,0" Name="button1" VerticalAlignment="Top" Width="75" />
        <Label Style="{StaticResource Style1}" Content="Label" Height="27" HorizontalAlignment="Left" Margin="189,99,0,0" Name="label1" VerticalAlignment="Top" Width="83" />
    </Grid>

Can’t we access style “Style1” with Button & Label in above example without setting Style property specifically in Button & Label controls?

Thanks in advance.

    Similar question as to here

    General consensus is that you cannot apply a style to something as esoteric as just the control. Considering the wide range of properties and controls, I can understand why the system rejects/ignores it. I would suggest maybe something like this to get you fairly close to what you would want:

    <Style x:Key="general" TargetType="{x:Type Control}">
        <Setter Property="Control.Background" Value="Green"/>
</Style>
<Style BasedOn="{StaticResource general}" TargetType="{x:Type Button}"/>
<Style BasedOn="{StaticResource general}" TargetType="{x:Type Label}"/>
<Style BasedOn="{StaticResource general}" TargetType="{x:Type CheckBox}"/>
