Display selected item in listbox.

[CSharpBeginner]

I have a weird issue that seems like it would be easy to fix.

I have a listbox that I make large enough to show 4 items at a time. Once the user selects the item they want, I reduce the size to show just one record - however, the record they selected does not show. How do I make it so that when the listbox is reduced, the highlighted/selected item is the only one that shows?

Let me know if you need to see my code, its C# winforms.

Thanks.

I moved the code for changing the size of the listbox from SelectedIndexChanged to the Click event and now it works like I wanted.
