Filtering Data with Queries

Queries in LightSwitch let you work with a subset of data. For example, instead of displaying all customers, you can use a query to display only those customers in a certain country or region.

In this set of lessons you will learn how to create both simple and parameterized queries and apply them to screens.

Note

These lessons build upon the My First Application project that you last modified in the Customizing the Running Application lesson. If it is not already open, open it from the File, Open Project menu.
