Error when binding repeater with IDataReader after converting asp.net 3.5 to 4.0

I am trying to migrate asp.net 3.5 application to asp.net 4.0 version.

asp.net 3.5 is working without any issues, after migrating to asp.net 4.0 getting the below error

"An invalid data source is being used for rptStudents. A valid data source must implement either IListSource or IEnumerable."

Note: Migrated to Enterprise lib开发者_如何学Gorary 5.0 from 4.1

Code:

Using drStudents As IDataReader = dbStudents.ExecuteReader(cmdStudents)
                With rptStudents
                    .DataSource = drStudents
                    .DataBind()
                End With

End Using

Davide:Thanks for your quick response.

drStudents is a IDataReader and this code is working good

Dim dbStudents As Database = DatabaseFactory.CreateDatabase("eCONNECTION") Dim cmdStudents As DbCommand = dbComments.GetStoredProcCommand("get_students")

Using drStudents As IDataReader = dbStudents.ExecuteReader(cmdStudents) With rptStudents .DataSource = drStudents .DataBind() End With End Using

What is the actual object type of the drStudents variable?

It is very clear from the error that IDataReader or the object you receive is not good anymore as DataSource and you should pass something that implements IListSource or IEnumerable
