On the close event, I want to make sure my datagrid has all the data updated with the database.  What code do I need to do this?

If your talking about Component Ones TrueGrid you would simply ReBind the grid to your data source.

If your talking about refreshing the grid based on the data in the database changing your would do this:
DataGrid.Refresh
DataGrid.ReBind

If your talking about update the database based on data changing in the grid you would use the _AfterUpdate event and update the database from the changed column values.

I want to update based on data changing in the grid.  Would this work after closing the screen?

Private Sub Form_Unload(Cancel As Integer)
DataGrid.ReBind
End
End Sub

No, you need to deal with the update on a row by row basis. When the grid is updated and the user moves off the row the _AfterUpdate event fires. In thisevent you would check for a change edit the data and update your database. If the user makes a change then closes the form the _AfterUpdate event still fires.
