我有一个关于在单击按钮时更改按钮背景图像的问题。

我尝试在谷歌上搜索，但找不到适合我的东西。

好吧，这是我的代码

<Button Grid.Column="0" Grid.Row="0" x:Name="btnHome" VerticalAlignment="Stretch" BorderBrush="{x:Null}" HorizontalAlignment="Stretch" Click="btnHome_Click" PointerEntered="btnHome_PointerEntered">
                <Button.Template>
                    <ControlTemplate TargetType="Button">
                        <Border x:Name="RootElement">
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="MouseOver">
                                        <Storyboard>
                                            //I want my background change here
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="Pressed">
                                        <Storyboard>
                                            //And here
                                        </Storyboard>
                                    </VisualState>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                            <Border.Background>
                                <ImageBrush ImageSource="images/back_button.png"/>
                            </Border.Background>
                        </Border>
                    </ControlTemplate>
                </Button.Template>
            </Button>

我也试过这个

private void btnHome_PointerEntered(object sender, PointerRoutedEventArgs e)
    {
        BitmapImage bmp = new BitmapImage();
        Uri u = new Uri("ms-appx:images/back_button_mouseover.png", UriKind.RelativeOrAbsolute);
        bmp.UriSource = u;
        ImageBrush i = new ImageBrush();
        i.ImageSource = bmp;
        btnHome.Background = i;
    }

但不幸的是，这都不起作用

使用WinRT Xaml Toolkit，您可以获得所有效果。从工具包中引用二进制文件。将 xml 命名空间添加到您的页面：

xmlns:controls="using:WinRTXamlToolkit.Controls"

使用按钮，如：

<controls:ImageButton HorizonalAlignment="Center"
    NormalStateImageSource="normal.png"
    HoverStateImageSource="hover.png"
    PressedStateImageSource="pressed.png" />

除此之外，它还有很多有用的东西。

这是一种样式，可以打开和关闭您在 Blend 中添加的一些额外图像的可见性。图像是透明的，并且通过使用“Send to Back”在按钮背景图像后面。换句话说，您可以继续为每个按钮使用不同的背景图像画笔，以及交换的 Normal、Pointer 和 Pressed 图像。所以两个背景图像重叠。

我找到了这个问题的答案。

您必须编辑控件的模板。

您可以使用 Blend 或“手动”来完成。

检索按钮的默认模板（通过按右键、编辑模板、编辑副本、为其命名并按确定），然后对其进行自定义以满足您的需求

编辑：这是关于 RadioButton 模板自定义的 MSDN 资源。

我正在使用这段代码：

<Button Style="{StaticResource anyButton}" Cursor="Hand" ClickMode="Press" Click="Button_Click_1" />

风格：

        <Style x:Key="anyButton" TargetType="Button">
        <Setter Property="OverridesDefaultStyle" Value="True"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="border" 
                    BorderThickness="0" 
                    Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="False">
                            <Setter Property="Background" TargetName="border">
                                <Setter.Value>
                                    <ImageBrush ImageSource="C:\Users\image1.png" />
                                </Setter.Value>
                            </Setter>
                        </Trigger>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" TargetName="border">
                                <Setter.Value>
