I have a drop down which, when the user types, I want to present them with the correct option from the drop down list which matches what they type.

I want this to happen with the dropdown open though. Anyone know how to make a dropdown ...erm... drop down using code without the user having to click it?

Something like with a treeview, where you can set ...

Node.Expanded = True

...is there any way to set ...

MyDropDown.Opened = True

... or something like that?

Cheers.
