Question

我有以下的樣式定義WPF造型邊框厚度...

<!-- Blue Button --> 
<Style x:Key="BlueButton" TargetType="{x:Type Button}"> 
    <Setter Property="OverridesDefaultStyle" Value="True"/> 
    <Setter Property="Template"> 
    <Setter.Value> 
     <ControlTemplate TargetType="Button">     
    <Border Name="border" 
     BorderThickness="2" 
     Padding="4,2" 
     CornerRadius="5" 
     BorderBrush="{TemplateBinding BorderBrush}" 
     Background="{TemplateBinding Background}"> 
     <Grid > 
     <ContentPresenter 
     HorizontalAlignment="Center" 
     VerticalAlignment="Center" 
     Name="content"/> 
     </Grid> 
    </Border> 
    <ControlTemplate.Triggers> 
     <Trigger Property="IsMouseOver" Value="True"> 
     <Setter Property="Background" Value="{DynamicResource BlueGradientOver}"/> 
     <Setter Property="BorderBrush" Value="White"/> 
     </Trigger> 
     <Trigger Property="IsEnabled" Value="False"> 
     <Setter Property="Background" Value="Black"/> 
     <Setter Property="BorderBrush" Value="White"/> 
     <!-- how do I set the BorderThickness here? --> 
     <Setter Property="Foreground" Value="White"/> 
     </Trigger>    
     <Trigger Property="IsPressed" Value="True"> 
     <Setter Property="Background" Value="{DynamicResource BlueGradient4}"/> 
     <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient1}"/> 
     </Trigger> 
    </ControlTemplate.Triggers> 
     </ControlTemplate> 
    </Setter.Value> 
    </Setter> 
    <Setter Property="SnapsToDevicePixels" Value="true"/> 
    <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> 
    <Setter Property="Background" Value="{DynamicResource BlueGradient1}"/> 
    <Setter Property="BorderBrush" Value="{DynamicResource BlueGradient2}"/> 
    <Setter Property="Foreground" Value="White"/> 
    <Setter Property="HorizontalContentAlignment" Value="Center"/> 
    <Setter Property="VerticalContentAlignment" Value="Center"/> 
    <Setter Property="TextBox.TextAlignment" Value="Center"/> 
    <Setter Property="FontFamily" Value="Trebuchet MS"/> 
    <Setter Property="FontSize" Value="15pt"/> 
    <Setter Property="Effect" Value="{DynamicResource KioskStandardDropShadow}" /> 
    <Setter Property="IsEnabled" Value="True"/> 
</Style> 

我想改變BorderThickness財產當按鈕被禁用，但我想不出該怎麼辦它。

在您的控件模板中，您將BorderThickness設置爲2！它應該是：

您是否嘗試過Expression Blend 4？它具有非常好的直觀用戶界面，可直接處理XAML上的行爲和觸發器以及活動。你應該試試看！生成所有代碼可能需要5分鐘（包括您的邊框）。
