我正在尝试Grid使用GridSplitter单击按钮时隐藏列中的列(该按钮将第三列中所有项目的可见性设置为折叠).如果我不移动GridSplitter它正常工作,第三列消失,但如果我移动GridSplitter内容消失但其他列不调整大小以填充空白空间.

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="25"/>
    </Grid.RowDefinitions>

    <Grid.ColumnDefinitions>
        <ColumnDefinition x:Name="a" Width="*"/>
        <ColumnDefinition x:Name="b" Width="3"/>
        <ColumnDefinition x:Name="c" Width="Auto" MaxWidth="600"/>
    </Grid.ColumnDefinitions>
    <Border Grid.Column="0" Grid.Row="0" HorizontalAlignment="Stretch" Background="Green">
        <Image Source="te/Dante.png" Height="Auto" Margin="0,128,2,71"/>
    </Border>
    <Button Grid.Column="0" Grid.Row="0" Width="30" Height="30" Margin="0,10,10,0" HorizontalAlignment="Right" VerticalAlignment="Top" Click="Button_Click"></Button>
    <GridSplitter Width="5" Grid.Column="1" Grid.Row="0" Grid.RowSpan="2" ResizeDirection="Columns" HorizontalAlignment="Left" Background="White" BorderBrush="Black" BorderThickness="1,0" ResizeBehavior="PreviousAndCurrent"/>
    <WrapPanel x:Name="wpC" Grid.Column="2" Grid.Row="0" Grid.RowSpan="2" MinWidth="300" HorizontalAlignment="Stretch" Background="Aqua" Panel.ZIndex="-1"></WrapPanel>
</Grid>

这是我的问题的一个例子(gif):

我怎么解决这个问题？可能尊重MVVM模式.
