WPF：自定义按钮答案

【问题标题】：WPF : Custom ButtonWPF：自定义按钮
【发布时间】：2015-08-23 09:27:31
【问题描述】：

我尝试像这样在 wpf 中编辑样式：

允许用户设计，像这样

但是当我尝试创建自己的样式时，有铬层而不是模板，我无法创建自己的按钮，我只能修改像画笔这样的简单值，......

【问题讨论】：

老实说，如果你从一个教程开始会更好，比如this one。如果您让 Blend 在您的应用程序中转储大量代码，您将不会学到太多东西。只是我的两分钱。
我同意@MikeEason：这个问题看起来更像是在线辅导和代码编写服务的请求。最好的问候，

【解决方案1】：

Milad 只需删除该 chrome 层并在模板中包含边框（编写您自己的鼠标悬停和单击触发器）：

<Border x:Name="Chrome" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
                            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Border>

触发器：

<ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="true">
                                <Setter Property="Background" TargetName="Chrome" Value="Blue"/>
                            </Trigger>
                            <Trigger Property="IsEnabled" Value="false">
                                <Setter Property="Foreground" Value="#ADADAD"/>
                            </Trigger>
                        </ControlTemplate.Triggers>

为什么有 chrome，在旧版本的 blend (v
Milad，chrome 是他们用于样式的类是presentationframework。它还有一些属性，如 RenderPressed 等。

Micrsoft MSDN (https://msdn.microsoft.com/en-us/library/ms753328%28v=vs.110%29.aspx) 中提供了非常详细的 WPF Button 通过 XAML 控制样式的规范示例：

XAML

<Style x:Key="ButtonFocusVisual">
  <Setter Property="Control.Template">
    <Setter.Value>
      <ControlTemplate>
        <Border>
          <Rectangle Margin="2"
                     StrokeThickness="1"
                     Stroke="#60000000"
                     StrokeDashArray="1 2" />
        </Border>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

不客气！当然，您也可以将此样式技术应用于其他控件。这种高级 XAML 样式是在实际的 WPF 应用程序中完成的：这里是一个包含大量 WPF 示例应用程序（免费下载）的网站链接：infosoft.biz/download.aspx。祝你的项目好运。最好的问候，
