我对列中的内容使用SizeChanged事件。

<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
    <Grid.ColumnDefinitions>
        <ColumnDefinition x:Name="leftColumn" MinWidth="268" Width="268*"/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition x:Name="centerColumn" MinWidth="327" Width="327*"/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition x:Name="rightColumn" MinWidth="393" Width="393*"/>
    </Grid.ColumnDefinitions>
    <custom:Control x:Name="panel1" Grid.Column="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,0,0,5" SizeChanged="PanelSizeChanged"/>
    <GridSplitter Grid.Column="1" Background="#00000000" HorizontalAlignment="Center" VerticalAlignment="Stretch" ResizeBehavior="PreviousAndNext" Width="5" ResizeDirection="Columns"/>
    <custom:Control x:Name="panel2" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,0,0,5" SizeChanged="PanelSizeChanged"/>
    <GridSplitter Grid.Column="3" Background="#00000000" HorizontalAlignment="Center" VerticalAlignment="Stretch" ResizeBehavior="PreviousAndNext" Width="5" ResizeDirection="Columns"/>
    <custom:Control x:Name="panel2" Grid.Column="4" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,0,0,5" SizeChanged="PanelSizeChanged"/>
</Grid>

我在一个回调PanelSizeChanged中管理我需要的所有大小更改内容。当然，您可以为每列使用不同的处理程序。
