I have 3 datagrids linked together via data environment:

dgCustomer is parent to dgContact, dgContact is parent to dgInvoice.

It is working well when the form loads... the dg3 reprensents the dgInvoice shows the records for the selected Contact and the dgContact shows the good contact for the selected customer.

The problem: as soon as I select another customer, the good contact are shown in the dgContact but the dgInvoice is empty... and stays this way even when I go back to the first customer... this dataGrid is empty except on the formLoad.

Anyone as an idea?

No code is necessary to refresh the grids with the dataEnvironment

Have you created hierarcical commands? What I suggest is that you use the DataForm wizard to generate a Master/Detail form and look at the code when changing record. You will see that some code is required to refresh the grids.

Yes, it is well formed. When I change an Invoice, then I requery the recordset and re-bind the dataGrids, it is working again, but the same thing appens as on formLoad.

Any Idea?

Yes but the code I have is only when I update some data... but the problem I have is when I click on my dgCustomer... the dgContact refreshes correctly, but with the dgInvoice nothing appens. And I do nothing much (or less) between those two.

You better go using code. See the DataForm Wizard.

I know I can make it work using something else than the data Environment... but I want to use the date Environment because there is no code to make it work... all I want to know is if it works properly.
