In my MVC Helper, when I set the combobox mode to "ReadOnly", the first item is automatically selected instead of the combobox being blank. I assume this is a bug? Any suggested work-arounds?
Hello JoshNoe,
This is the default behavior of igCombo when ReadOnly and ReadOnlyList mode is used: If AllowCustomValue is disabled and SelectedIndex or SelectedValues is not set, then first matching item in list will be selected.

If you want to have the combobox blank you can set explicitly the text option

Another possible work around is to add additional blank item at the beginning of the data which will be chosen by default.
