Detailed Description
BackgroundGrid is the grid that displays behind a Map in a MapView, or a Surface in a SceneView. If there is no map or surface provided, an empty view will display with only the BackgroundGrid. The BackgroundGrid is not associated with the Grid that can be displayed over a MapView. The Map displays on top of the background grid or the optional Map.backgroundColor to determine what is displayed under transparent areas of the map.
An instance of this class can be used to set a default backdrop that a Map or Scene will display on top of.
Example:
Change the MapView's background grid (JavaScript):
var newGrid = ArcGISRuntimeEnvironment.createObject("BackgroundGrid"); newGrid.color = "white"; newGrid.gridLineColor = "black"; newGrid.gridLineSize = 5; newGrid.gridSize = 50; mapView.backgroundGrid = newGrid;
Property Documentation
color : color |
The fill color of the background. The default value is Silver ("#C0C0C0").
gridLineColor : color |
The color of the background grid lines. The default value is Black ("#FFFFFF").
gridLineWidth : double |
The width of the grid lines in device-independent pixels (DIP). The default value is 1.
This value must be greater than or equal to 0. Setting the grid line width to 0 will make grid lines invisible.
gridSize : double |
The size of each grid square in device-independent pixels (DIP). The default value is 20 x 20 pixels.
[since Esri.ArcGISRuntime 100.3] visible : bool |
true if grid lines are visible on the color, false otherwise.
In the context of MapView, this value indicates if the gridLineColor is visible. In the context of SceneView, this value indicates if both the color and the gridLineColor are visible. The default value is true.
This property was introduced in Esri.ArcGISRuntime 100.3.
