DataGridTextColumn Visibility Binding

Question

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>

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')

Is there a pure XAML way to accomplish this?

Answer 1

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}}"
