Datagrid Class

Uses
Defined in: src\js\RAMP\Modules\datagrid.js:12
Module: Datagrid
Parent Module: RAMP

The Datagrid class represents the side bar table shown next to the map. The data grid displays all map objects in a text format and allows the user to see more details (same as clicking the map object) and navigate to the object. This class create the UI panel, events, and event-handles for the data grid container.
