Question

Could someone with some good knowledge answer this question please. Im having a problem with the schema in my Students.aspx page. I have done the walkthrough, but I get an error and I have copied the edmx file from the sample into my application and I still get the error. This is the error:

‘EnrollmentDate’ is not a member of
type ‘SchoolModel.Person’ in the
currently loaded schemas. Near simple
identifier, line 6, column 4.

I have also created a new EntityDataSource and I have the same problem. The sample works fine but I can’t seem to get the EnrollmentDate and HireDate fields to be part of the ‘SchoolModel.Person’ Entity. The part which is Upto setting the EntityTypeFilter then I run the app and I get problems

Answer 1

It sounds like you’re following the example on MSDN. By the end of the example, the fields EnrollmentDate and HireDate are no longer on the SchoolModel.Person class, they’re on the subclasses SchoolModel.Instructor and SchoolModel.Student.
