WPF将3个对象组合成一个区域按钮

Question

首先我为我的英语道歉。

我正在制作一个简单的c# WPF应用程序。我已经添加了一个椭圆，label1,label2到我的MainWindow.xaml.

我想把这3个对象(ellipse,label1,label2)做成一个按钮。我想要这个按钮加载我的第二个wpf页面，称为"大小"。据我所知，它应该是一个区域按钮。我试过使用"border"(来自WPF控件)和"MouseDown"(来自事件处理程序)，但效果不是那么好。任何建议吗?我该怎么办?

事件处理程序的代码是:

   private void Border_MouseDown(object sender, MouseButtonEventArgs e)
    {
        Size secondPage = new Size();
        secondPage.Show();
        this.Close();
    }

你需要重新定义按钮样式，你可以使用ControlTemplate。下面是如何编写可重用样式来重新定义按钮的示例。

我还添加了一个如何实现IsPressed事件的颜色变化的例子。

<Window x:Class="ColorTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <ResourceDictionary>
        <LinearGradientBrush x:Key="ButtonBackground" StartPoint="0,0" EndPoint="1,1">
            <GradientStop Color="#FFD9EDFF" Offset="0"/>
            <GradientStop Color="#FFC0DEFF" Offset="0.445"/>
            <GradientStop Color="#FFAFD1F8" Offset="0.53"/>
        </LinearGradientBrush>
        <Style x:Key="SimpleButtonStyle" TargetType="{x:Type Button}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Grid>
                            <Border Background="{StaticResource ButtonBackground}" VerticalAlignment="Stretch" CornerRadius="2" HorizontalAlignment="Stretch"/>
                            <Border x:Name="BorderPressed"  Opacity="0" Background="Blue" VerticalAlignment="Stretch" CornerRadius="2" HorizontalAlignment="Stretch"/>
                            <Label Name="label1" Content="1" HorizontalAlignment="Left"></Label>
                            <Label Name="label2"  Content="2" HorizontalAlignment="Right"></Label>
                            <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" x:Name="MainContent" />
                        </Grid>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsPressed" Value="True">
                                <Trigger.EnterActions>
                                    <BeginStoryboard>

                                        </Storyboard>
                                    </BeginStoryboard>

                                </Trigger.ExitActions>
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>

<DockPanel>
    <Button Content="Button" Height="23" Name="button1" Width="75" Style="{StaticResource SimpleButtonStyle}" Click="button1_Click"/>
