Refreshing data in a DataGridView - with complex dataSource

Hello Everyone:

I've some WinForms dataGridViews with a complex dataSource. Specifically the DataSource is fed from a custom tableAdapter with a query from two tables.

When I update the database records, I can't get the DataGridViews to refresh the way I normally do it for a regular tableAdapter (with only one table).

• The TableAdapter feeds off both the Personnel_Tbl and the List_JobRanks Table.
• My load routine follows

 // Load data into the 'aBC_ShiftDataSet.Personnel_Tbl' table.
this.personnel_By_ListRankTableAdapter.Fill_By_ListRank(this.aBC_ShiftDataSet.Personnel_By_ListRank);

• 
  
  The queries are constructed into a custom table adapter named: personnel_By_ListRank

Typically this would refresh my DataGridView and show changes to the underlying database. But, it's not doing so. I figure it's because I'm using a TableAdapter that queries two tables.

So... I thought maybe I should fill the tableAdapters of both queried tables - as follows:

// Load data into the 'aBC_ShiftDataSet.Personnel_Tbl' table. 

this.personnel_TblTableAdapter.Fill(this.aBC_ShiftDataSet.Personnel_Tbl);
this.list_JobRanksTableAdapter.Fill(this.aBC_ShiftDataSet.List_JobRanks);
this.personnel_By_ListRankTableAdapter.Fill_By_ListRank(this.aBC_ShiftDataSet.Personnel_By_ListRank);

But that doesn't work either.

The underlying database records are being updated. If I preview the data in the DataSet Designer I can see the updates there. The problem seems to be refreshing my DataGridViews. More details about my DataGridView construction follow:

• The queries are constructed into a custom table adapter named: personnel_By_ListRank
• SQL for personnel_By_ListRank follows

SELECT Personnel_Tbl.PersonnelID, Personnel_Tbl.LName, 
Personnel_Tbl.FName, Personnel_Tbl.Rank, 
Personnel_Tbl.Shift, Personnel_Tbl.StationAssignment, 
Personnel_Tbl.HireDate, Personnel_Tbl.BirthDate, 
Personnel_Tbl.Address, Personnel_Tbl.City, 
Personnel_Tbl.State, Personnel_Tbl.ZipCode, 
Personnel_Tbl.FullName, Personnel_Tbl.Phone1, 
Personnel_Tbl.Phone1_Desc, Personnel_Tbl.Phone2, 
Personnel_Tbl.Phone2_Desc, List_JobRanks.RnkColor, 
List_JobRanks.RnkOrder FROM Personnel_Tbl INNER JOIN 
List_JobRanks ON Personnel_Tbl.Rank = List_JobRanks.Rank 
ORDER BY List_JobRanks.RnkOrder, Personnel_Tbl.FullName

DataGridView Construction example follows:

• Name of DataGridView: Unassigned_dataVW
• Binding Source for Unassigned_dataVW is unassignedBindingSource
• DataMember property for unassignedBindingSource is Personnel_By_ListRank
• DataSource property for unassignedBindingSource is aBC_ShiftDataSetT

Thanks in advance for advice on how to refresh the dataGridViews and showing updates to the database.
