WPF设置样式的几种方式
第一种方式是直接使用Setter来进行，可以对Background等进行设置。
<Window.Resources> <Style TargetType="Button"> <Setter Property="Background" Value="Red"/> </Style></Window.Resources>
第二种是直接将比较复杂一点的Style放置到Window.Resources中：
<Window.Resources> <LinearGradientBrush x:Key="CheckedState" StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="#FFE7E1E1" Offset="0"/> <GradientStop Color="black" Offset="1"/> <GradientStop Color="gray" Offset="0.581"/> </LinearGradientBrush> </Window.Resources>
使用的时候，直接利用 Background="{StaticResource CheckedState}"即可。
第三种是利用Template方式来进行，这种可以进行比较复杂的样式制作：
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="WpfApplication4.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <LinearGradientBrush x:Key="CheckedState" StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="#FFE7E1E1" Offset="0"/> <GradientStop Color="black" Offset="1"/> <GradientStop Color="gray" Offset="0.581"/> </LinearGradientBrush> <LinearGradientBrush x:Key="UnCheckedState" StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="#FFE7E1E1" Offset="0"/> <GradientStop Color="gray" Offset="1"/> <GradientStop Color="gray" Offset="0.581"/> </LinearGradientBrush> <Style TargetType="TabItem"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="TabItem"> <Grid> <Border Name="Border" BorderThickness="1" BorderBrush="Gray" Background="{StaticResource UnCheckedState}" Width="80" Height="25" Margin="0,0,1,0" CornerRadius="4,4,0,0"> <Grid> <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True" /> </Grid> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="Panel.ZIndex" Value="100" /> <Setter TargetName="Border" Property="Background" Value="{StaticResource CheckedState}" /> <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" /> </Trigger> <Trigger Property="IsEnabled" Value="False"> <Setter TargetName="Border" Property="Background" Value="{StaticResource DisabledBackgroundBrush}" /> <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource DisabledBorderBrush}" /> <Setter Property="Foreground" Value="{StaticResource DisabledForegroundBrush}" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value>
