This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So stop trying to type as little as possible and give us actual information! Try an example: inputs and outputs, what happens when. Show us what you have tried so far and explain what it did that you didn't expect, or didn't do that you did.

Use the "Improve question" widget to edit your question and provide better information.

How about you start by telling us which of the many different "combobox" controls that VB.NET has access to is the one you're using?

Is this Windows Forms? WPF? Xamarin? ASP.NET WebForms? ASP.NET MVC? Something else?

Unfortunately this is a "quick" answers forum and not a tutorial site.

See the good advice from OriginalGriff and also please read the posting guidelines.

A little research first is always a good idea - try these resources[^]

If you still have a problem after you have tried ideas from that list come back with your specific problem and we will try to help.

I can only repeat what I said. This is not a tutorial forum. What ideas from the list I gave you have you actually tried?
