从 C# 代码动态切换 WPF 网格列的可见性

问题描述

限时删除！！

我的问题是:我不知道如何切换 WPF 网格列的可见性.假设以下 XAML 标记:

My problem is: I can't find out how to toggle the visibility of my WPF grid column. Assume following XAML markup:

<Grid x:Name="myGrid">
    <Grid.RowDefinitions>
        <RowDefinition x:Name="Row1" />
        <RowDefinition x:Name="Row2" />
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition x:Name="Column1" />
        <ColumnDefinition x:Name="Column2" />
    </Grid.ColumnDefinitions>
</Grid>

在网格中填充了一些控件等.现在我想从我的 C# 代码中动态隐藏单个列.我尝试通过将列的定义宽度设置为零来实现这一点，例如Column1.Width = 0.这有效，但我不太喜欢这个解决方案 - 真的没有更好的方法吗?

Aferwards the grid is filled with some controls etc. Now I want to hide a single column dynamically out of my C# code. I've tried achieving this by setting the the column's definition width to zero, e.g. Column1.Width = 0. This works, but I don't really like this solution - is there really no better way?

我正在寻找类似 myGrid.Columns[0].Visibility = COLLAPSED 或 Column1.Visibility = HIDDEN 的东西.我就是找不到类似的东西 - 有什么想法吗?

I'm looking for something like myGrid.Columns[0].Visibility = COLLAPSED or Column1.Visibility = HIDDEN. I just can't find something like that - any ideas?

推荐答案

<ColumnDefinition>
  <ColumnDefinition.Style>
    <Style TargetType="ColumnDefinition">
      <Setter Property="Width" Value="*" />
        <Style.Triggers>
          <DataTrigger Binding="{Binding IsColumnVisible}" Value="False">
            <Setter Property="Width" Value="0" />
          </DataTrigger>
        </Style.Triggers>
    </Style>
  </ColumnDefinition.Style>
</ColumnDefinition>

请在您的 ViewModel 中实现 INotifyPropertyChanged

Please do implement INotifyPropertyChanged in your ViewModel
