I am really not sure what event procedures to use for a ComboBox control pertaining to a particular application. Here is my scenario.
First off, both ComboBoxes have the "Droppeddown" property set to true when the control receives focus. The 2nd ComboBox is populated based on the value from the 1st ComboBox.
Next, which events should be fired:
1. When a user uses a mouse to select data from the list?
2. When a user uses the up/down arrow to select data from the list?
Thanks,

By using this event, it doesn't allow me to scroll down thru the items using the arrow keys. As soon as I pick the first different value, the procedure fires. I need to be able to scroll thru the items and press the enter key or tab key to make the selection.
blake I told you in your original thread you made about this you should be using listboxes and not combooxes, as they just don't have this functionality.
Is there a reason you can't use listboxes for this instead?
The closest you can probably get to the functionality you want, is to use the DropDownClosed event of the combobox which fires when the dropdown portion closes.
Keep in mind though you won't want any code in this event that will take focus away from your control and bring it back (like a messagebox) otherwise you will get a weird UI loop.
The listbox takes up too much space. Aesthetically, it doesn't look right. Can you set listbox properties to be like combobox properties?
some of them yes, but you would need to be specific about the properties.
Did you look at the dropdownclosed event of the combobox?
Yes, I looked at it but it would require alot of logic changes.
I think the only way you will the exact functionality you want, is going to be to inherit the combobox to a new control, and override wndproc to look for specific windows messages, and raise custom events on these messages.
Looks like I'm gonna have to just improvise because what your talkin' about....I have no clue on how to do.
