Answer 1

Either use the combobox in ajax toolkit ( see http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/ComboBox/ComboBox.aspx ) or create a custom control containing a textbox, button and a list and toggle the visibility as necessary (button-click- toggle visibility of the list, typing in the textbox- filter the data in the list and show the list , click inside textbox- could hide the list).

Answer 2

The ComboBox in the Ajax Control Toolkit provides the behavior you are after.
