我为我的 Silverlight 按钮创建了一个样式模板，设法创建了圆角和悬停状态，可以毫无问题地更改大部分样式，但是...

我不知道如何使Foreground颜色改变hover。

请参阅下面的代码，我遇到问题的部分目前已被注释掉。

    <Style TargetType="Button" >
        <Setter x:Name="myFontColor" Property="Foreground" Value="#000000"/>
        <Setter Property="FontSize" Value="11"/>
        <Setter Property="FontStyle" Value="Normal"/>
        <Setter Property="FontFamily" Value="Arial"/>
        <Setter Property="FontWeight" Value="Normal"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <Grid Height="28">
                        <Border x:Name="myBorder" BorderBrush="#C4C4C4" BorderThickness="1" CornerRadius="5">

                                <Rectangle.Fill>
                                    <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                        <GradientStop x:Name="GradientStop1" Color="#FDFDFD" Offset="0" />

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

作为 Silverlight 的新手，我希望这只是一个针对正确元素和样式的简单问题。

我该如何去Foreground改变颜色hover？

首先，在ContentPresenter里面放一个ContentControl（这有 Foreground 属性）然后你可以改变它，就像你对背景所做的那样：

<Style TargetType="Button" >
    <Setter x:Name="myFontColor" Property="Foreground" Value="#000000"/>
    <Setter Property="FontSize" Value="11"/>
    <Setter Property="FontStyle" Value="Normal"/>
    <Setter Property="FontFamily" Value="Arial"/>
    <Setter Property="FontWeight" Value="Normal"/>
    <Setter Property="Padding" Value="0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <Grid Height="28">
                    <Border x:Name="myBorder" BorderBrush="#C4C4C4" BorderThickness="1" CornerRadius="5">
                        <Rectangle x:Name="BackgroundGradient" RadiusX="5" RadiusY="5">
                            <Rectangle.Fill>
                                <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                                    <GradientStop x:Name="GradientStop1" Color="#FDFDFD" Offset="0" />
                                    <GradientStop x:Name="GradientStop2" Color="#D6D6D6" Offset="1" />
                                </LinearGradientBrush>
                            </Rectangle.Fill>
                        </Rectangle>
                    </Border>
                    <!-- CONTENT CONTROL HERE -->
                    <ContentControl Name="content" VerticalAlignment="Center" HorizontalAlignment="Center">
                    <ContentPresenter  />
                    </ContentControl>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommomStates">
                            <VisualState x:Name="Normal" />
                            <VisualState x:Name="MouseOver">
                                <Storyboard>
                                    <ColorAnimation 
                                        Storyboard.TargetName="GradientStop1"
                                        Storyboard.TargetProperty="Color"
                                        From="#FDFDFD" To="#0A284B" 
                                        Duration="0"
                                        />
                                    <ColorAnimation 
                                        Storyboard.TargetName="GradientStop2"

                                        />

                                    <ColorAnimation 
                                        Storyboard.TargetName="myBorder"

您可以通过添加事件 MouseEnter 和 MouseLeave 并在事件中更改颜色来做到这一点

例子：

<Button x:Name="myButton" 
    Content="Button" 
    MouseEnter="myButton_MouseEnter" 
    MouseLeave="myButton_MouseLeave"/>

在 C# 类中，你必须有方法

    private void myButton_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e)
    {
        myButton.Foreground=new SolidColorBrush(Colors.Red);
    }

    private void myButton_MouseLeave(object sender, System.Windows.Input.MouseEventArgs e)
    {
        myButton.Foreground=new SolidColorBrush(Colors.White);
    }

希望，这就是你要找的。

使用 Blend 来设计任何控件。使用它，您可以轻松创建任何您想要的样式

只需通过创建一个按钮

试试这个：

    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="BorderBrush">
        <Setter.Value>
