Set winform combobox list height-CodePudding

I have a combobox which can have a different number of items at any given time. I have the list count set to 8 and it works fine. But if the list is actually less than 8 then it shows the extra blank lines. How can I shrink the height based on the number of items in the list if less than 8?

Thank you.

You can iterate the combobox with foreach and remove when the value is null

Eureka! Knew it was easy.

List<String> _reasons = new List<String>() {"a","b"};
if (_reasons.Count < Reason.Properties.DropDownRows)
    Reason.Properties.DropDownRows = _reasons.Count;
