I don't think you can. At least not that easily. The reason is because it needs to be drawn at run-time, so the system needs to know how it's going to be rendered. You're trying to change the rules of the game and it's bottom of the 8th inning. That's not how it works.
At least not that easily. Depending on what you're trying to do, you would be better off with multiple cbo's and swap them in/out as needed .... ooooooorrrr.... you take ownership of rendering the cbo yourself and make it ownerdrawn, and then take care of it in the paint event.
So the question is - just what is it exactly you're trying to do here?
I put together a UC that does it. It's sort of customized to my needs, but I'll post it.
It's really just meant to toggle between DropdownList and DropdownCombo.
The secret is all in the AllowTyping property.
Also, after throwing together my little demo, I realize that I only intended to set it in Form_Load, and never change it. It'll take a bit more work if you wish to change it after the user is looking at it, as the Text property may be a bit confusing.
In my case, I have certain fields that are a bit user-dependent. Some users like to be restricted to a pre-defined list, whereas others like to add items not on the list on-the-fly.
Enjoy,
Elroy
