WPF Combobox linking issue

Question

I have 2 comboboxes and based on selection in 1st one I want to populate 2nd one. How can I do this with two classes Country and City?

You can take below approach: First create Country class that would contain country related information and all available city values in a collection. Somewhere in your code instantiate a collection of the country and the corresponding cities. In XAML bind the ItemSource property of the combobox to that property. For 2nd combobox bind it's ItemSource property to the list of cities from the SelectedItem of the first combobox. Hope it will resolve your linking issue.
