Episerver在编辑模式下自定义网格中的复杂数据类型

我目前正在使用episerver 9 cms。Episerver在编辑模式下自定义网格中的复杂数据类型

我有我的页/块如下：

public class MenuBlock : SiteBlockData 
    { 

     [Display(
      Name = "Menu title", 
      Description = "* Required", 
      GroupName = SystemTabNames.Content, 
      Order = 1)] 
     public virtual string MenuTitle { get; set; } 


     [Display(
      Name = "Section", 
      Description = "Add menu sections", 
      GroupName = SystemTabNames.Content, 
      Order = 3)] 
     [EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor<SectionBlock>))] 
     public virtual IList<SectionBlock> Section { get; set; } 

    } 

public class SectionBlock 
    { 
     [Display(
      Name = "Section name", 
      Description = "Select the Menu Image", 
      GroupName = SystemTabNames.Content, 
      Order = 1)] 
     public virtual string SectionName { get; set; } 

     [Display(
      Name = "Dishes", 
      Description = "Dishes", 
      GroupName = SystemTabNames.Content, 
      Order = 2)] 
     [EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor<DishBlock>))] 
     public virtual IList<DishBlock> Dishes { get; set; } 
    } 

public class DishBlock 
    { 
     [Required(ErrorMessage = "Dish name is required")] 
     [Display(Name = "Dish name", 
      Description = "* Required", 
      GroupName = SystemTabNames.Content, 
      Order = 1)] 
     public virtual string DishName { get; set; } 

     [Display(
      Name = "Dish description", 
      Description = "", 
      GroupName = SystemTabNames.Content, 
      Order = 2)] 
     [UIHint(UIHint.Textarea)] 
     public virtual string DishDescription { get; set; } 

     [Display(
      Name = "Price", 
      Description = "", 
      GroupName = SystemTabNames.Content, 
      Order = 4)] 

     public virtual double Price { get; set; } 

    }
