Solution 1

For the first combobox you normally get the data and bind it to the combobox. You bind the other one in SelectedValueChanged event of the first one in which you get the data for the second depending on SelectedValue of the first.

If this helps please take time to accept the solution. Thank you.

You do know how to bind the combobox, right? What have you tried? I've described the process and if you know how to bind the data then you just have to use SelectedValueChanged event. If you're looking for a free code, you're in a wrong place. If you need help with binding the combobox, you should have phrased your question differently. And there are plenty of examples easily found via google. Please describe exactly what you need...and why. Thank you.
