Question

我有3个网格 - 1个主网格，包含2个子网格。我希望ScrollViewer只出现在一个子网格中。如何才能做到这一点？ ScrollViewer要么不显示（设置为自动时），要么显示，但禁用时没有位置指示（设置为可见时）。我能够将它应用到主网格并且它可以工作，但不能用于子网格。在主网格的情况下，所有高度都设置为自动，因此我假设相同的设置也适用于子网格，但它没有。以下是我的代码摘录：

<UserControl x:Class="StoreMgmtSys.Views.IssueInfoPage" Height="Auto" Width="Auto">
  <Grid x:Name="layoutGridMaster" Height="Auto" Width="Auto" ShowGridLines="False">
    <ScrollViewer CanContentScroll="False" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
      <Grid x:Name="gridEqpItem" Height="Auto" Grid.Row="0" Grid.Column="0">
      </Grid>       
    </ScrollViewer>
    <Grid x:Name="layoutGridIssue" Grid.Row="0" Grid.Column="1" Margin="0,0,0,0">
    </Grid>
  </Grid>
</UserControl>

编辑 - 想要通过ScrollViewer了解我的网格内容的人的附录：

Answer 1

终于解决了我的问题。问题在于我的主网格的RowDefinition（我没有在我的问题中透露代码）。诀窍是将第一个RowDefinition高度设置为＆＃34; *＆＃34;如下所示。最初我的代码是＆＃34; Auto＆＃34;。不要问我为什么;我不知道如何解释，因为我的编程概念还不是很好。

<Grid x:Name="layoutGridMaster" Height="Auto" Width="Auto" ShowGridLines="False">
  <Grid.ColumnDefinitions>
    <ColumnDefinition Width="Auto" />
    <ColumnDefinition Width="*" />
  </Grid.ColumnDefinitions>
  <Grid.RowDefinitions>
    <RowDefinition Height="*" />
    <RowDefinition Height="Auto" />
    <RowDefinition Height="Auto" />
  </Grid.RowDefinitions>
  .
  .
  .
</Grid>

将ScrollViewer分配给网格中的网格
