Question

我有一个有三行的网格，前两行之间有一个GridSplitter。第三行包含一个按钮。当GridSplitter被拖动到窗口的中心或下部时，一切都会很好地调整大小。当GridSplitter被拖动到窗口顶部时，第二行无法正确调整大小，第三行被切断。

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:clr="clr-namespace:System;assembly=mscorlib"
    Width="300" MinHeight="300"  >
  <Grid ShowGridLines="True">
    <Grid.RowDefinitions>
      <RowDefinition MinHeight="130" />
      <RowDefinition MinHeight="50" />
      <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Rectangle Grid.Row="0" Fill="Aquamarine"/>
    <GridSplitter Grid.Row="0" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Height="5" />
    <ScrollViewer Grid.Row="1" >
      <Rectangle Height="500" Fill="Orange"/>
    </ScrollViewer>
    <Button Grid.Row="2" Content="Close" Width="70" HorizontalAlignment="Right" Margin="5" Click="Close_Click"/>
  </Grid>
</Window>

Answer 1

你的行MinHeight值是罪魁祸首。

我测试了你的代码，当我调整窗口大小时，你正在描述的问题发生了，而不是当我拖动分割器时。

创建第二个网格并移出按钮将有所帮助。

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:clr="clr-namespace:System;assembly=mscorlib"
    Width="300" MinHeight="300"  >
    <Grid ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Grid ShowGridLines="True">
            <Grid.RowDefinitions>
                <RowDefinition MinHeight="130" />
                <RowDefinition MinHeight="50" />
            </Grid.RowDefinitions>

            <Rectangle Grid.Row="0" Fill="Aquamarine"/>
            <GridSplitter Grid.Row="0" VerticalAlignment="Bottom" HorizontalAlignment="Stretch" Height="5" />
            <ScrollViewer Grid.Row="1" >
                <Rectangle Height="500" Fill="Orange"/>
            </ScrollViewer>

        </Grid>
        <Button Grid.Row="1" Content="Close" Width="70" HorizontalAlignment="Right" Margin="5"/>
    </Grid>
</Window>

网格内的ScrollViewer导致行无法正确调整大小
