我正在尝试使用右侧的标题创建扩展器，而不是向该扩展器添加网格。当我运行此网格文本块时不出现。并且想知道在右侧创建扩展头的最佳方法是什么。

那么如何在扩展器中获取网格的数据呢？

存在三个问题

  1. 是，所以在扩展器内容区域中什么都看不到MainExpanderControlNormalForegroundBrush。White将其更改为黑色，如下所示。

    <SolidColorBrush x:Key="MainExpanderControlNormalForegroundBrush" Color="Black" />

  2. 在其中一个触发器中，您将绑定到名称Content不存在的元素。您应该绑定到ContentBorder如下所示。

    <Trigger Property="IsExpanded" Value="True">
    <Setter TargetName="ContentRow" Property="Height" Value="{Binding ElementName=ContentBorder, Path=DesiredHeight}" />
</Trigger>

  3. 将您的ContentRow高度设置为 0 以带来扩展器功能。

    <RowDefinition Name="ContentRow" Height="0"/>
