DataGridTextColumn 可见性绑定 [英] DataGridTextColumn Visibility Binding

问题描述

我正在尝试将列可见性绑定到另一个元素的可见性，如下所示:

I'm trying to bind column visibility to that of another element like this:

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" />
</Window.Resources>
<StackPanel>
    <CheckBox x:Name="chkColumnVisible" Content="Show column" />
    <DataGrid x:Name="MyDataGrid" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Column1" Visibility="{Binding ElementName=chkColumnVisible, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter}}"/>
        </DataGrid.Columns>
    </DataGrid>
</StackPanel>

但我在 VS 输出中收到此错误:

but I get this error in VS output:

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=IsChecked; DataItem=null; target element is 'DataGridTextColumn' (HashCode=48860040); target property is 'Visibility' (type 'Visibility')

是否有一种纯粹的 XAML 方法来实现这一点?

Is there a pure XAML way to accomplish this?

推荐答案

DataGrid 的列是不出现在可视化或逻辑树中的抽象对象.您不能使用 ElementName 和 RelativeSource.Source 结合 x:Reference 应该可以工作:

The columns of a DataGrid are abstract objects not appearing in the visual or logical tree. You cannot use ElementName and RelativeSource. Source in combination with x:Reference should work though:

Visibility="{Binding Source={x:Reference chkColumnVisible},
                     Path=IsChecked,
                     Converter={StaticResource BooleanToVisibilityConverter}}"
