How to display a control inside an existing control ?

Question

Hello I've been trying to do something for a while but I don't know what is the best way to go about it. Basically I have a control (a ListBox) and for configuration purposes I would like to temporarily show a new control in the middle of it. For example I have my ListBox and when the mouse cursor enters it a ComboBox appears in the middle of this ListBox. When the mouse cursor leaves it it disappears. The problem is not how to catch these events but how to handle the control display. Thanks for you help :)

It's all about events. When a selection changes move the combobox to fill the item rectangle of the selected item. If nothing is selected hide the combobox. Also you'll want to set the text of the combobox to the current item. I'll see if I can provide you an example if this is not clear.
