I forgot to mention This.mlListLikeCombo is a custom property that I set to .T. when I require this functionality.

>I wanted to have a combobox that used key pneumonics (DropDown List) but if the user pressed UPARROW or DNARROW the combobox would be existed appropriately (DropDown Combo). If I put the following code into the combobox I get exactly what I wanted:
>

>.KeyPress Event
>IF This.Style=2 AND This.mlListLikeCombo
>	IF nKeyCode=5 OR nKeyCode=24		&&UPARROW or DNARROW
>		This.Style=0					&&Set .Style to DropDown Combo
>		DODEFAULT()
>	ENDIF
>ENDIF
>
>.Valid Event
>IF This.Style=0 AND This.mlListLikeCombo
>	This.Style=2						&&Set .Style back to DropDown List
>ENDIF
>

>However, when I put the same code into my combobox class it doesn't work properly. The combobox does exit as expected but the .Value is blanked out. Any help on this would be greatly appreciated. My users prefer this combined functionality and I would hate to have to have this code in every combobox ever used.
