The DisplaySettings contains information about how to display a map resource (service) on the map. Usually the DisplaySettings are stored as a string in the page source for the MapResourceManager and typically are defined at design time in Visual Studio by using the resource items editor for the MapResourceManager. The editor stores the display settings as a string. The DisplaySettings object reads this string and parses it into its properties. These settings are then used when the map resources are displayed on a Map control.

The DisplaySettings properties include whether to make the data source Visible on the Map, the percentage Transparency of the data source, the properties of the images requested (ImageDescriptor), and whether to DisplayInTableOfContents.
