Activate ComboDropDown.PopupContainer through PreviewKeyDown Event

[Adrian Negrillo]

I have a ComboDropDown that contains a TreeView as the PopupControl. I want to be able to open the ComboDropDown and display the TreeView programatically by using the PreviewKeyDown or another KeyPress Event, when the user presses the Down Arrow on the keyboard.

PopupContainer.ShowPopup(control.Location) doesn't seem to work. Below are other options I've tried:

- PopupContainer.Show()

- PopupContainer.Controls[0].Select

- PopupContainer.Select()

- PopupControl.Select

- TreeView.Select
