Question

我想在下面创建如下所示的结构，它应该包含2个堆栈面板：

一个水平（HPanel）
一个垂直（VPanel）

扩展器应位于HPanel的右侧，当点击扩展器时，两个面板都应该折叠并且放大。反之亦然

HPanel - ＆gt;扩展
V
P
一个
ñ
Ë
我

Answer 1

要获得右侧的按钮，您将不得不重新模拟扩展器。这是您需要的完整xaml：

</Grid>

这将产生一个如下所示的控件：

如果您可以使用左侧的按钮，则解决方案变得更加容易：

<toolkit:Expander>
        <toolkit:Expander.Header>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="Horizontal1  "/>
                <TextBlock Text="Horizontal2  "/>           
            </StackPanel>       
        </toolkit:Expander.Header>
        <StackPanel Orientation="Vertical">
            <TextBlock Text="Vertical1"/>  
            <TextBlock Text="Vertical2"/> 
            <TextBlock Text="Vertical3"/>        
        </StackPanel>
    </toolkit:Expander>

产生这个：
