Constructors
LayerView() Constructor
Parameterless constructor for use as a Razor Component.
public LayerView();
LayerView(LayerType, Nullable, Nullable, Nullable, Nullable, Nullable, Nullable) Constructor
Constructor for use in C# code. Use named parameters (e.g., item1: value1, item2: value2) to set properties in any order.
public LayerView(dymaptic.GeoBlazor.Core.Enums.LayerType type, System.Nullable<bool> spatialReferenceSupported=null, System.Nullable<bool> suspended=null, System.Nullable<bool> updating=null, System.Nullable<bool> visibleAtCurrentScale=null, System.Nullable<bool> visibleAtCurrentTimeExtent=null, System.Nullable<bool> visible=null);
Parameters
type LayerType
The type of layer view.
spatialReferenceSupported System.Nullable<System.Boolean>
Indicates if the spatialReference of the MapView is supported by the layer view.
ArcGIS Maps SDK for JavaScript
suspended System.Nullable<System.Boolean>
Value is true if the layer is suspended (i.e., layer will not redraw or update itself when the extent changes).
ArcGIS Maps SDK for JavaScript
updating System.Nullable<System.Boolean>
Indicates if the layer view is making any updates that will impact what is displayed on the map.
default false
ArcGIS Maps SDK for JavaScript
visibleAtCurrentScale System.Nullable<System.Boolean>
When true, the layer is visible in the view at the current scale.
default true
ArcGIS Maps SDK for JavaScript
visibleAtCurrentTimeExtent System.Nullable<System.Boolean>
When true, the layer is visible in the view’s timeExtent.
default true
ArcGIS Maps SDK for JavaScript
visible System.Nullable<System.Boolean>
When true, the layer is visible in the view.
default true
