嗨，大家好我有这样的代码，

<RichTextBox />
  <Expander Header="expand">
   <Grid>
    <Rectangle />
   </Grid>
  </Expander>

虽然我已经折叠了扩展器，但我仍然无法访问richtextbox，因为richtextbox位于扩展器层下。当扩展器折叠时我如何访问richtextbox？

如果您将对象放置在网格的同一行和同一列中，它们将会重叠。这两个对象都位于网格的第 0 行和第 0 列中。

我不确定你想实现什么目标。如果您不希望对象重叠，请使用 DockPanel 或 StackPanel 来放置它们，或者如果您要使用网格，请将它们放在不同的位置行，例如：

<Grid>  
  <Grid.RowDefinitions>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
  </Grid.RowDefinitions>
  <RichTextBox Grid.Row="0">
    <FlowDocument>
       <Paragraph>
        <Run Text="Now this doesn't overlap."/>
       </Paragraph>
    </FlowDocument>
  </RichTextBox>
  <Expander Header="expand" Grid.Row="1">
  <Grid>
    <Rectangle />
  </Grid>
  </Expander>
</Grid>

If you're laying out objects in the same row and column of a grid, they're going to overlap. Both of those objects are in row 0 and column 0 of the grid.

I'm not sure what you're trying to accomplish. If you don't want the objects to overlap, use a DockPanel or StackPanel to lay them out, or if you're going to use a grid, put them in different rows, e.g.:

<Grid>  
  <Grid.RowDefinitions>
    <RowDefinition Height="Auto"/>
    <RowDefinition Height="Auto"/>
  </Grid.RowDefinitions>
  <RichTextBox Grid.Row="0">
    <FlowDocument>
       <Paragraph>
        <Run Text="Now this doesn't overlap."/>
       </Paragraph>
    </FlowDocument>
  </RichTextBox>
  <Expander Header="expand" Grid.Row="1">
  <Grid>
    <Rectangle />
  </Grid>
  </Expander>
</Grid>
