without you passing a piece of code gets a little complicated, but I will try to answer you so that you can understand with ease, come on...

Your combobox1 has an event that runs every time you select a value (I don’t know if you’re using Windows Forms or WPF so I can’t tell you the event name for sure). In this event you will schedule the routine that will load the cities in your second combobox (combobox2)

Here is a similar question, maybe it will help you: https://stackoverflow.com/questions/6850932/c-sharp-setting-up-data-bound-cascading-combo-boxes-at-design-time

You can also search for "Cascading combobox on c#" in Google, for sure you will find many examples and tutorials.

Hugs.
