Question

亥目前我有这样的网格。

    <Grid  Name="tGrid1"  Grid.Row="0" Background="Black" >
    </Grid>



    <Grid Name="Grid2"  Grid.Row="1"  Background="LightBlue" >
    </Grid>



    <Grid Name="Grid3"  Grid.Row="2" Background="LightGray" Height="auto" >

    </Grid>




    <Grid Name="Grid4"   Grid.Row="3"   Background="LightGreen" >
    <Button HorizontalAlignment="Left" IsEnabled="True" Margin="13.5,5,0,5" Name="TestBtn" Width="50" Click="test_Click" >Test</Button>
    </Grid>

</Grid>

我想要的是，当我单击测试按钮时，网格1和网格2必须折叠，并且空间必须占用网格3.这意味着外网格的总高度超出500，网格3应该占用height = 465，Grid 4应该是ocupy Height = 35。我怎样才能做到这一点？我该如何更改Grid的高度定义？ Thanx提前冠者

Answer 1

不确定这是否是您所要求的，但在test_Click方法中您可以使用此功能：

  private void test_Click(object sender, RoutedEventArgs e)
  {
     tGrid1.Width = 0;
     tGrid1.Height = 0;
     Grid2.Width = 0;
     Grid2.Height = 0;

     Grid3.Height = 465;
     Grid4.Height = 35;
  }

如果“崩溃”是指“隐藏”，则可以将height和width tGrid1和Grid2设置为0来实现。

亥我找到了解决方案。

  <DockPanel  >
 <Grid  Name="tGrid1"  Grid.Row="0" DockPanel.dock="Top" Background="Black" >
 </Grid>

 <Grid Name="Grid2"  Grid.Row="1"  DockPanel.dock="Top" Background="LightBlue" >
 </Grid>

<Grid Name="Grid4"   Grid.Row="3"  DockPanel.dock="Bottom"  Background="LightGreen" >
<Button HorizontalAlignment="Left" IsEnabled="True" Margin="13.5,5,0,5" Name="TestBtn" Width="50" Click="test_Click" >Test</Button>
 </Grid>

<Grid Name="Grid3"  Grid.Row="2" DockPanel.dock="Top" Background="LightGray" Height="auto" >

</Grid>
</DockPanel>




 private void test_Click(object sender, RoutedEventArgs e)
  {
     tGrid1.visibility=visibility.collapsed;
Grid2.visibility=Visibility.collapsed;
  }

这很好用。谢谢冠者
