Class GeoView
A base class for all views that can display geographic content.
Inheritance
Implements
Namespace: Esri.ArcGISRuntime.Maui
Assembly: Esri.ArcGISRuntime.Maui.dll
Syntax
public abstract class GeoView : View, INotifyPropertyChanged, IDynamicResourceHandler, INameScope, IVisualTreeElement, IEffectControlProvider, IToolTipElement, IContextFlyoutElement, INavigationProxy, IAnimatable, IViewController, IVisualElementController, IElementController, IGestureController, IGestureRecognizers, IPropertyMapperView, IHotReloadableView, IReplaceableView, IGeoView, IView, IElement, ITransformRemarks
Subclasses can display the content in either 2D (MapView) or 3D (SceneView). In an MVC 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 (Map) or a scene (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.
Fields

Properties
| Name | Description |
|---|---|
| AttributionText | Gets the attribution text for the data that is currently displayed in the GeoView. |
| DrawStatus | Gets the current drawing status of the content displayed in the GeoView. |
| GraphicsOverlays | Gets or sets a collection of GraphicsOverlay objects used to display graphics on top of the view's content. |
| Grid | Gets or sets the grid that is available to the map for display. |
| 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. |
| IsWrapAroundEnabled | Gtes a value indicating whether the wrap around feature is currently active. For wrap around to be active the WrapAroundMode property must be set to true and the SpatialReference of the MapView control must be a SpatialReference that supports wrapping. |
