TextBox默認模板

Question

我有一個TextBox，當我將它懸停時，邊框將顏色改爲藍色。我如何禁用此行爲？

XAML：

<Canvas> 
    <Grid Canvas.Left="100" Canvas.Top="100" Width="200" Height="100"> 
     <TextBox></TextBox> 
    </Grid> 
</Canvas> 

Answer 1

一個簡單的「黑客」，你可以用它來禁用邊框動畫時IsMouseOver是真正的是讓一個小改動，BorderThickness。例如BorderThickness="1.000001"

<Canvas> 
    <Grid Canvas.Left="100" Canvas.Top="100" Width="200" Height="100"> 
     <TextBox BorderThickness="1.000001"/> 
    </Grid> 
</Canvas> 

Answer 2

你必須定義在卸下故事板鼠標懸停狀態的風格。 它應該是這樣的（測試SL）：

<UserControl.Resources> 
     <Style x:Key="NoMouseOverTextBoxStyle" TargetType="TextBox"> 
      <Setter Property="BorderThickness" Value="1"/> 
      <Setter Property="Background" Value="#FFFFFFFF"/> 
      <Setter Property="Foreground" Value="#FF000000"/> 
      <Setter Property="Padding" Value="2"/> 
      <Setter Property="BorderBrush"> 
       <Setter.Value> 
        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 
         <GradientStop Color="#FFA3AEB9" Offset="0"/> 
         <GradientStop Color="#FF8399A9" Offset="0.375"/> 
         <GradientStop Color="#FF718597" Offset="0.375"/> 
         <GradientStop Color="#FF617584" Offset="1"/> 
        </LinearGradientBrush> 
       </Setter.Value> 
      </Setter> 
      <Setter Property="Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="TextBox"> 
         <Grid x:Name="RootElement"> 
          <VisualStateManager.VisualStateGroups> 
           <VisualStateGroup x:Name="CommonStates"> 
            <VisualState x:Name="Normal"/>

如果你想要這個的所有文本框，看看隱樣式（http://www.silverlightshow.net/items/Implicit-Styles -in-Silverlight的4.aspx）。
