Prevent Edit of a Combo Box

Posted on 2002-06-03
Last Modified: 2012-06-27
I have several combo boxes in an application I'm working on. I don't want to allow the users to just type something into the combo box - infact - I want them to be able to select ONLY a list item in the combo box.

I am still not sure if I want to allow them to type in the field (and catch the case where the typed value does not exist in the list) or to completely stop typing in the field. My personal preference (and from what I can tell the easier of the two options) would be the later.

I've played with validate, and lost focus. They don't quite behave how I want them to. For example, a user could type in string, click the continue button. This would call the lost_focus event which would determin that the string was bad, set the combo to some value (user would have no control of this) and then continue on...

Any ideas/code fragments greatly appriecated.

If I understand you correctly, what you're looking for is in the Style property...set it to 2-Dropdown List.

Set the listindex property to correspond to the item you want.  (Points go to rspahitz)

Combo1.Text = IntialValue


Combo1.ListIndex = Item_Between_0_And_ListCount-1

Glad to help.

yes -- got the listindex as soon as I looked at it, not sure why I hadn't thought to use the style property! had been playing with everything from lccked, enabled, to on_lost_focus, to validate...
