I can't seem to get a combo that is bound to have a drop down style other than DropDownList (i.e. only values in list can be selected...no random typing allowed).



This is related to binding. If the combo is unbound, then when the style is set to DropDown, I can type arbitrary values into the combo.



However, if the combo is bound, the style becomes DropDownList (no matter what I set at design time).



I checked the source code (I'm not on the latest beta currently ) and in the BindingEditable property is manipulating the drop down style. I'm thinking it isn't handling the original style correctly and just ends up setting it to drop down list.



The workaround is to set the combo to ignore editing changes and manage that yourself if needed.

Do you get the same behavior if you set the IgnoreManageReadonlyState to True?
