I am developing a WPF/C# app that is partially functional.
It has ComboBoxes, TextBoxes, and DatePickers that are all bound to a multi-table accdb query, and it has navigation buttons(First Record, Previous Record, Next Record, and Last Record).
The TextBoxes show initial values when the app is first loaded, but the ComboBoxes do not. Also, when I use the navigation buttons, the TextBoxes update to current values of the newly-selected record, but the ComboBoxes do not. The ComboBoxes only accept values manually from the respective ItemsSource.
How can I cause my ComboBoxes to inherit and display values from the currently-selected ACCDB query record, beginning when the window is initially opened?
