How to change [DisplayName] of EF generated class properties?
asp.net-mvc, asp.net-mvc-4, ef-database-first, entity-framework
Solution
Use a metadata class and attach it to your entity class via the MetadataTypeAttribute. You specify your data annotation attributes on the properties in the metadata class (no implementation for said properties).
MSDN: http://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.metadatatypeattribute.aspx
Edit: an initial gotcha is the namespace of the partial class you define to attach the MetadataTypeAttribute. Be sure to change its namespace to the namespace used by the original entity so that it is defining the same class.
Problem
We know EF generates classes based on Tables we added to `.edmx` file. Which will not any [DisplayName] DataAnnotations for them. How can I add this [DisplayName] of generated classes without modifying them? because generated classes can be overridden If I modify `.edmx` file (re add the modified table) if database changes. So I don't want modify generate class itself. EF Generated Class ``` public partial class Committee { public string Committee_Description { get; set; } public byte[] Committee_Id { get; set; } public string Rn_Descriptor { get; set; } public Nullable<System.DateTime> Rn_Create_Date { get; set; } ...... ..... ``` View ``` <tr> <th> @Html.DisplayNameFor(model => model.Item2.GetEnumerator().Current.Committee_Name) </th> ```
