Bonnie,

Thank you! But my findings and the statements in MacDonald's book are the same. The navigation is controlled by a complex binding control, I quoted the exact page from his book previously.

Otherwise, I am confused how .NET automatically connects the navigation without a command? Can you please explain it? Please, I do not understand how this automatic connection occurs without an instruction - please help me here, because I do not understand this automatic connection - please. To be clear: How does the navigation get automatically connected in .NET - this I wish I could get explained. MacDonald just says it happens.

Also, my case was two different tables, two different datasets, clearly .NET was choosing (and here is the issue, it was CHOOSING) the wrong control.

Your example shows the same table, or copies of it, assigned to two different comboboxes, that was not what I was doing. I explained I had a customer table and a salesperson table - my example was a customer data entry window. .NET was setting the navigation control to be the salesperson combobox (there was NO customer combobobox or "complex control").

Again, thank you, as I said, my limited understanding was the result of missing documentation, i.e. "The Binding property sets the binding"

But please answer the automatic navigation setting, please.
