Class GeoView

public abstract class GeoView : ViewGroup, Drawable.ICallback, IAccessibilityEventSource, KeyEvent.ICallback, IViewManager, IViewParent, IDefaultLifecycleObserver, ILifecycleObserver, IJavaObject, IJavaPeerable, IDisposable, INotifyPropertyChanged

Remarks

Subclasses can display the content in 2D (MapView), global 3D (SceneView), or local 3D (LocalSceneView). In an MVVM architecture, this class and its subclasses represent the View tier. The Model tier is represented by GeoModel, which supplies the geographic content as a Map or a Scene.

GeoView contains all the common operations and events that apply to displaying and working with maps and scenes. For example, you can change the viewable area by setting a Viewpoint, work with graphics in the GraphicsOverlay, and identify a GeoElement that displays in the view.

Properties

Name	Description
AnalysisOverlays	Gets or sets a collection of analysis overlays that render the analysis results on the view.
AttributionText	Gets the attribution text for the data that is currently displayed in the GeoView.
CalloutStyle	Gets or sets the CalloutStyle for callouts on this GeoView.
CriticalError	Gets the critical error on the view.
DrawStatus	Gets the current drawing status of the content displayed in the GeoView.
GeoModelError	Gets the geo model error on the view.
GraphicsOverlays	Gets or sets a collection of GraphicsOverlay objects used to display graphics on top of the view's content.
Grid	Gets or sets a coordinate system grid to display on top of the GeoView.
ImageOverlays	Gets or sets a collection of overlays for displaying images in the view.
IsAttributionTextVisible	Gets or sets a value indicating whether the Esri attribution text is visible.
IsCalloutVisible	Gets a value indicating whether a callout is currently open
IsNavigating	Gets a value indicating whether the map is currently navigating. when navigation has finished the NavigationCompleted event will be raised.

Labeling	Gets or sets the ViewLabelProperties.
SelectionProperties	Gets or sets the selection properties for all graphic overlays and selectable layers within the GeoView.
SpatialReference	Gets the spatial reference that defines the coordinate system used by the map or scene in the GeoView.
TimeExtent	Gets or sets TimeExtent of the GeoView.
ViewInsetsBottom	Gets the bottom view inset
ViewInsetsLeft	Gets the left view inset
ViewInsetsRight	Gets the right view inset
ViewInsetsTop	Gets the top view inset
