This is a concise, user-friendly way to add intuitive functionality to a form that controls one or more lists of entries. It is optimized for 10-Key operators but will also work for QWERTY-mode users.
Drop a Textbox and a Listbox onto the UI; place them close together and name them similarly. For example, txtSerialNumber and lbSerialNumber. Add a ToolTip to the form, toolTip1.
Create event handlers for:
* KeyDown on the Textbox.
* DragDrop, DragOver, KeyDown, and SelectedIndexChanged on the Listbox.
