WPF的DataGrid：绑定的DataGridColumn知名度的ContextMenu的MenuItems器isChecked（MVVM） [英] WPF DataGrid: Binding DataGridColumn visibility to ContextMenu MenuItems IsChecked (MVVM)

问题描述

我想通过一个文本菜单可用于控制的DataGrid 列知名度，用户右键单击列标题。在文本菜单显示所有可用列的名称。我使用MVVM设计模式。

I want to control DataGrid column visibility through a ContextMenu available to the user by right-clicking the column header. The ContextMenu displays the names of all available columns. I am using MVVM design pattern.

我的问题是：我如何绑定的DataGridColumn 的能见度属性设置为器isChecked 的属性菜单项位于文本菜单。

My question is: How do I bind the DataGridColumn's Visibility property to the IsChecked property of a MenuItem located in the ContextMenu.

一些样机code：

<UserControl.Resources>         
    <ContextMenu x:Key="ColumnHeaderContextMenu">  
        <MenuItem Header="Menu Item..1" IsCheckable="True" />  
    </ContextMenu>  
    <Style x:Key="ColumnHeaderStyle" 
           TargetType="{x:Type toolkit:DataGridColumnHeader}">  
        <Setter Property="ContextMenu" 
                Value="{StaticResource ColumnHeaderContextMenu}" />  
    </Style>  
    <BooleanToVisibilityConverter x:Key="booleanToVisibilityConverter" />  
</UserControl.Resources>

...flaf flaf flaf

<toolkit:DataGrid x:Name="MyGrid" AutoGenerateColumns="False" 
    ItemsSource="{Binding MyCollection, Mode=Default}" 
    EnableColumnVirtualization="True" IsReadOnly="True" 
    ColumnHeaderStyle="{StaticResource ColumnHeaderStyle}">  
    <toolkit:DataGrid.Columns>  
        <toolkit:DataGridTextColumn Binding="{Binding Path=MyEntry}" 
            Header="MyEntry" Visibility="{Binding IsChecked, Converter=
                {StaticResource booleanToVisibilityConverter}.... />
    </toolkit:DataGrid.Columns>     
</toolkit:DataGrid>  

如果我是不清楚，请让我知道，我将试图阐述。

If I am being unclear please let me know and I will attempt to elaborate.

干杯，

推荐答案

我刚写了一篇关于这一主题的博客文章。它允许显示或通过文本菜单，通过右键单击任何列标题是可访问的隐藏DataGridColumns。这个任务是通过附加属性纯粹的完成，因此是MVVM兼容。

I just wrote a blog post on this topic. It allows DataGridColumns to be shown or hidden through a ContextMenu that is accessible by right-clicking any column header. This task is accomplished purely through attached properties so it is MVVM-compliant.
