Creating And Removing Choice List Using Visual Studio LightSwitch 2012

Introduction

This article describes how to create a list of values for any particular field using LightSwitch Visual Studio 2012.

Choice List in LightSwitch

We develop a "Choice List" so that users can easily choose a value from a given set instead of entering a value into a text box on its own.

Creating a Choice List
