Dataset Column Order Problem

I created a dataset with several TableAdapters built in it.  I have one query that builds a datatable of all users in the system.  I can bind to the gridview without a problem and the results are correct.  However, the order of the columns is not consistant with my query.  For example, Select col1, col2, col3 from table, is displaying in the gridview as col2, col1, col3.

Use the following

MyDataSet.Tables["MyTable"].Columns["MyColumn"].SetOrdinal(5);  
This puts the Column "MyColumn" to the 6th position in the columns order (0 based index).

Thanks

Can you explain further?  How would I fit that into my code?  My code is below.

       ' Fill Gridview with Users
        Dim usersAdapter As New UsersTableAdapter
        gvUsers.DataSource = usersAdapter.GetUsers()
        gvUsers.DataBind()

It seems to me that you need to add "ORDER BY col1, col2, col3" to your dataset query...

An ORDER BY shouldn't effect the order in which the columns appear, that's what the SELECT statement is for.  

To elaborate further:
SQL Statement -> SELECT Name, Username, Email, Active, Role FROM Users ORDER BY Name

Displays in the gridview in the following order -> Email, Active, Username, Role, Name.

I'm attempting to use a layered architecture to design the system.  I created a .xsd file for the Data Access Layer.

Sorry, I misunderstood what you were saying...
And, you can manually change the order of the GridView columns... (from the template)

Apparently everytime I made a change to a field it put it last.  For instance, original column order: A B C.  I make a change to column B in the query and the new order is now A C B.  I'm using Visual Web Developer 2008.

I was originally databinding my gridview through the Page_Load event.  Now, I created an Object Data Source and binded my gridview to that.  Different approach but it solved my problem in a round about way.
