【WPF】DataGrid动态绑定隐藏列 DataGridTextColumn.Visibility

方法一：

前端

 <FrameworkElement x:Name="dummyElement" Visibility="Collapsed"/>
    <DataGrid>
        <DataGrid.Columns>
            <DataGridTextColumn Header="Test"
                                Binding="{Binding Name}"
                                Visibility="{Binding DataContext.Visible,
                                          Source={x:Reference dummyElement}}"/>
        </DataGrid.Columns>
    </DataGrid>

方法二：

前端

<Window.Resources>
    <ResourceDictionary>
        <FrameworkElement x:Key="ProxyElement" DataContext="{Binding}" />
    </ResourceDictionary>
</Window.Resources>

<!-- Necessary for binding to resolve: adds reference to ProxyElement to tree.-->
<ContentControl Content="{StaticResource ProxyElement}" Visibility="Collapsed" />
<mch:MCHDataGrid Height="350"
                  AutoGenerateColumns="False"
                  FlowDirection="LeftToRight"
                  ItemsSource="{Binding PayStructures}"
                  SelectedItem="{Binding SelectedItem}">
    <DataGrid.Columns>
         <DataGridTemplateColumn Width="70"
                                 Header="name"
                                 IsReadOnly="True"
                                 Visibility="{Binding DataContext.Visible,
                                 Source={StaticResource ProxyElement}}">
             <DataGridTemplateColumn.CellTemplate>
                 <DataTemplate>
                     <TextBlock Text="{Binding FieldName}" />
                 </DataTemplate>
             </DataGridTemplateColumn.CellTemplate>
         </DataGridTemplateColumn>                   
     </DataGrid.Columns>
</mch:MCHDataGrid>

后端窗体下加个属性即可

public System.Windows.Visibility Visible 
{
 　　get{return _visible;}
 　　set{_visible=value; OnPropertyChanged("Visible");}
}

private System.Windows.Visibility _visible;
