Question

可以说我是WPF的初学者。

我的GridSplitter行为很奇怪；网格分为5行。

标签栏
水平网格
分割器
另一个标签栏
文本框（txtLog）

类似于下面的代码，但是当我移动分隔符时，txtLog向下移动，而不是跟随先前的选项卡。

在外部网格中，尝试在第二个RowDefinition中将“高度”从*设置为“自动”

...
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="50" MinHeight="50" />
        <RowDefinition Height="Auto" MinHeight="120" />
        <RowDefinition Height="10" />
        <RowDefinition Height="50" MinHeight="50"/>
        <RowDefinition Height="*" MinHeight="120" />
    </Grid.RowDefinitions>
    <!-- TOOLBAR -->
...
