>Without the new keyword, the compiler tells me I'm hiding an inherited member and if that is the intended behavior, I should use new. So, while this compiles fine, when I try to use this control on a WinForm in another project, that property still defaults to DropDown (not DropDownLlist). I'm sure it has to be something simple I'm missing. By the way, I built this in a class project instead of a component project, does that make a difference?

Is the control on your form inherits from MyComboBox?
