Grid Overlay widget
(Added at v2.5)
The Grid Overlay widget allows you to quickly render a United States Military Grid Reference System (MGRS) grid using client-side resources in a web app. The MGRS is an alphanumeric system based on the universal transverse Mercator (UTM) and universal polar stereographic map projections for identifying positions. An MGRS coordinate consists of a zone designation, an alphabetic 100,000-meter grid square designator, and numeric coordinates within the 100,000-meter grid square. The widget allows an app to display the MGRS grid dynamically at different index levels in the app based on the scale of the map display.
Configure the Grid Overlay widget
This widget can be set to open automatically when
an app starts. Hover over the widget and click the Do not open this widget when

to change the setting to Open this widget automatically when the app starts. (For widgets that you need to add to the app first, you can turn on this option after configuring the widget.)

In addition to setting display options when the widget is configured, you can set more display options once the widget is deployed in an application.
- From a deployed application, click the Grid Overlay widget to open the widget dialog box.
- Check the box to choose if the grid will continue to display when the widget is closed.
