Set the height of the ListControl of a DevExpress ComboBox-CodePudding

I have a DevExpress ComboboxEdit which can have a different number of items at any given time.

I have the list count set to 8 and it works fine.
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?

CodePudding user response：

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;
