Gridview Data Bind Error - asp.net

Question

I cannot get the GridView to bind to DataRowView with the datasource below, however it does work if I use the wildcard.?
THIS FAILS:
ERROR: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'EnrollmentsTbl.AutoNum'

However:
changing the SELECTCOMMAND="SELECT * FROM... allows it to work?

I need fields from bith tabes in the gridview so the wildcard is not going to work.

Answer 1

No help offered, but it appears I found a resolution/work-a-round:
Part of the problem was that when the wildcard (*) is used in the SELECT statement (SelectCommand) the fields returned from an INNER JOIN are mixed, some have table.column and others just column. example: if both tables contain AutoNum then table1.AutoNum and table2.AutNum are both returned - but if only one table has a field it is returned as only Field - this was the problem with setting the column names in the gridview that was causing my problem.
