How to set inner object Data property for a datagridview

Question

I have created Entity Framework for a model. I would like to access inner object and bind that inner object to a datagridview. I can access inner object but i cant set data property of datagridview to show this. Can any one please help me out Here the code I have two classes in EF. ItemMaster And Category.ItemMaster Contains Category Id.Category Contains Category Name. now in EF i can access Category Object like

 public static List<ItemMaster> GetAllItemMasters()
 {
 using (var itemContext = new EntitiesContext())
 {
        var items = itemContext.ItemMasters.Include("Category").Where(p=>  (p.IsDelete==   null || p.IsDeleted.Value == false)).ToList();
        return items;

添加对您的命名空间的引用（如果需要），然后将该项目拆箱到父类中。

((MyClass)Container.DataItem).MyInnerClassObject.SomePropertyValue
