The List Picker control is one of three selector controls that allow developers to recreate a popular first-party Windows Phone data input experience. List Picker is a text box input control that can be tapped by the user to display a separate window used for the selection of an item in a custom collection. List Picker is basically the Windows phone equivalent of the Combo Box control.
