Cannot find column ColumnName

[Declan Murphy]

I received the following error when user tried to perform sorting on certain columns that are referencing extended properties from partial class. Sys.WebForms.PageRequestManagerServerErrorException: Cannot find column ColumnName.

I am using partial class to extend classes generated by ORM. I have something similar to below:

public partial class Person //generated by ORM
{
   public int Id {get;set;}
   public string FirstName {get;set}
}
public partial class Person //hand written
{
   public DateTime CreatedOn {get;set;}
   public Gender Gender {get;set;}
}
public enum Gender
{
   Male = 1,
   Female = 2
}

Sorting will work on Id and FirstName columns. And will throw exception on CreatedOn and Gender properties. The thing I don't understand is that they are displayed properly but just not on the sorting.

Any ideas? Thanks in advance.
