Multiple resultsets to multiple DataGridView

[code green]

I am getting three resultsets from a stored procedure

//Create a DataAdapter, with the name of the stored procedure.
SqlDataAdapter MyAdapter = new SqlDataAdapter("findOrders", myConnection);

//Set the command type as StoredProcedure.
MyAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
DataSet DS = new DataSet();

I pass a few parameters then try to bind each resultset to three different DataGridView via DataSet and BindingSource.
I can get the first set into the first DataGridView showing Orders

MyAdapter.Fill(DS,"findOrders");
dbBindSource.DataSource = DS.Tables["findOrders"];
grdOrders.DataSource = dbBindSource;

But when I write the second set to the second DataGridView showing Customers, this also overwrites the first DataGridView with the same data.

dbBindSource.DataSource = DS.Tables["BB_findOrders1"];
grdCust.DataSource = dbBindSource;

If I try with the third set of Order lines, this overwrites the first and second.

dbBindSource.DataSource = DS.Tables["BB_findOrders2"];
grdPart.DataSource = dbBindSource

Am I missing a command or doing it completely wrong?

Hmm, I'm guessing I need three BindingSource instances....
