DataGridTextColumn能见度绑定

本文介绍了DataGridTextColumn能见度绑定的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想列知名度绑定到这样的另一个元素的：

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

<Window x:Class="WpfApplication1.MainWindow" xmlns="schemas.microsoft/winfx/2006/xaml/presentation" xmlns:x="schemas.microsoft/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>

但我得到这个错误在VS输出：

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')

有没有纯粹的XAML的方式做到这一点？

Is there a pure XAML way to accomplish this?

推荐答案

在的DataGrid 的列是在视觉或逻辑树没有出现抽象对象。不能使用的ElementName 和的RelativeSource 。 来源结合 X：参考 应的工作，虽然：

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}}"
