如何在WPF网格中隐藏行

https://www.orcode.com/question/581562_kaac0d.html

将行内容的可见性设置为“Collapsed”。这仅在RowDefinition的Height属性设置为“Auto”时才有效，因此行大小基于它的内容。 例如，

<Grid>  
  <Grid.RowDefinitions>
    <RowDefinition Height="Auto"  />
    <RowDefinition Height="Auto" />
    <RowDefinition Height="Auto" />
  Grid.RowDefinitions>
 
  <Border Grid.Row="0" BorderThickness="1" BorderBrush="Red"><TextBlock>Visible RowTextBlock>Border>
  <Border Grid.Row="1" BorderThickness="1" BorderBrush="Black" Visibility="Collapsed"><TextBlock>Hidden RowTextBlock>Border>
  <Border Grid.Row="2" BorderThickness="1" BorderBrush="Red"><TextBlock>Visible RowTextBlock>Border>
Grid>
