Question

我对WPF很新，所以请原谅我，如果这是“旧帽子”这些天......已经在网上/论坛上搜寻，但还没找到我需要的答案：

我有一个包含5列的WPF网格 - 三个用于数据，两个用于网格分割器，这（感谢此网站上的信息！）似乎工作并调整大小。但是 - 我需要能够显示/隐藏中间列。我可以这样做，但是当我隐藏中间列时，左手网格探测器仍会影响“隐藏”列 - 我需要在2和2之间有效切换。三个柱子。这是我的（原型）代码：

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Name="Col0" Width="*" />
        <ColumnDefinition Name="Col1" Width="auto" />
        <ColumnDefinition Name="Col2" Width="*" />
        <ColumnDefinition Name="Col3" Width="auto" />
        <ColumnDefinition Name="Col4" Width="auto" />
    </Grid.ColumnDefinitions>
    <GridSplitter Grid.Column="1" Height="100" HorizontalAlignment="Center" Margin="0" Name="GridSplitter1" VerticalAlignment="Stretch" Width="3" />
    <GridSplitter Grid.Column="3" Height="100" HorizontalAlignment="Center" Margin="0" Name="GridSplitter2" VerticalAlignment="Stretch" Width="3" />
    <Border BorderBrush="Silver" BorderThickness="1" Grid.Column="0" HorizontalAlignment="Stretch" Margin="0" Name="Border1" VerticalAlignment="Stretch" Background="#FFC84797" />
    <Border BorderBrush="Silver" BorderThickness="1" Grid.Column="2" HorizontalAlignment="Stretch" Margin="0" Name="Border2" VerticalAlignment="Stretch" Background="Black" />
    <Border BorderBrush="Silver" BorderThickness="1" Grid.Column="4" HorizontalAlignment="Stretch" Margin="0" Name="Border3" VerticalAlignment="Stretch" Background="#FFA60000">
        <Button Content="hide" Height="33" Name="butHide" Width="85" />
    </Border>
</Grid>

Private Sub butHide_Click(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles butHide.Click

    If butHide.Content = "hide" Then

        butHide.Content = "show"
        Col2.Width = New GridLength(0)
        Border2.Visibility = System.Windows.Visibility.Collapsed
        GridSplitter2.Visibility = System.Windows.Visibility.Collapsed

    Else()

        butHide.Content = "hide"
        Col2.Width = New GridLength(1, GridUnitType.Star)
        Border2.Visibility = System.Windows.Visibility.Visible
        GridSplitter2.Visibility = System.Windows.Visibility.Visible

    End If
End Sub

Answer 1

对您而言，最简单的方法就是为Grid.ZIndex="2"设置Border1，然后在点击事件中将ColumnSpan切换为1到3之间。

<Border Grid.Column="0"
        Grid.ZIndex="2"
        Name="Border1"
        .../>

代码

private void butHide_Click(object sender, RoutedEventArgs e)
{
    if (butHide.Content.ToString() == "hide")
    {
        butHide.Content = "show";
        Grid.SetColumnSpan(Border1, 3);
    }
    else
    {
        butHide.Content = "hide";
        Grid.SetColumnSpan(Border1, 1);
    }
}

Answer 2

另一种解决方案是将网格分割器放在要在其内容后面调整大小的同一列中，并为内容设置边距。请参阅此链接以获取参考解决方案：http://www.ehow.com/how_4546867_use-gridsplitter-wpf.html

    <Grid>
     <Grid.RowDefinitions>
      <RowDefinition></RowDefinition>
     </Grid.RowDefinitions>
     <Grid.ColumnDefinitions>
      <ColumnDefinition></ColumnDefinition>
      <ColumnDefinition></ColumnDefinition>
     </Grid.ColumnDefinitions>

     <GridSplitter Grid.Row="0" Grid.Column="0" HorizontalAlignment="Right" Width="4" Background="Yellow"/>
     <TextBlock Grid.Row="0" Grid.Column="0" Margin="0 0 4 0" Background="LightGray">Text Block</TextBlock>
     <TextBlock Grid.Row="0" Grid.Column="1" Background="LightGreen">Text Block 2</TextBlock>
     </Grid>
