Problem Using Stored Procedures

I'm having a problem using a stored procedure when trying to get all rows of a table.

I have a property (see code snippet) named "AllRows" which returns a strongly typed DataTable table of all rows in a SQL mdf DB.
When I execute, an Exception is caught and the message says that:
            LastError      "Unable to cast object of type 'System.Data.DataTable' to type 'DestinationDataTable'."

Stored procedure is also attached in code snippet.

Thanks, and Any help on this topic would be most appreciated.
