Maps

• MapView

  • Change viewpoint

  This sample demonstrates different ways in which you can change the viewpoint or visible area of the map.

  • Map rotation

  This sample illustrates how to rotate a map.

  • Display drawing status

  This sample demonstrates how to use the DrawStatus value of the MapView to notify user that the MapView is drawing.

  • Display layer view state

  This sample demonstrates how to get view status for layers in a map.

  • Take Screenshot

  This sample demonstrates how you can take screenshot of a map. Click 'capture' button to take a screenshot of the visible area of the map. Created image is shown in the sample after creation.

  • Show magnifier

  This sample demonstrates how you can tap and hold on a map to get the magnifier. You can also pan while tapping and holding to move the magnifier across the map.

• Map

  • Display a map

  This samples demonstrates how to display a map with a basemap

  • Open an existing map

  This sample demonstrates how to open an existing map from a portal. The sample opens with a map displayed by default. You can change the shown map by selecting a new one from the populated list.

  • Set Min & Max Scale

  This sample demonstrates how to set the minimum and maximum scale of a Map. Setting the minimum and maximum scale for the Map can be useful in keeping the user focused at a certain level of detail.

  • Access load status

  This sample demonstrates how to access the Maps' LoadStatus. The LoadStatus will be considered loaded when the following are true: The Map has a valid SpatialReference and the Map has an been set to the MapView.

  • Set initial map location

  This sample demonstrates how to create a map with a standard ESRI Imagery with Labels basemap that is centered on a latitude and longitude location and zoomed into a specific level of detail.

  • Set initial map area

  This sample demonstrates how to set the initial viewpoint from envelope defined by minimum (x,y) and maximum (x,y) values. The map's InitialViewpoint is set to this viewpoint before the map is loaded into the MapView. Upon loading the map zoom to this initial area.

  • Set map spatial reference

  This sample demonstrates how you can set the spatial reference on a Map and all the operational layers would project accordingly.

  • Change basemap

  This sample demonstrates how to dynamically change the basemap displayed in a Map.

  • Manage Bookmarks

  This sample demonstrates how to access and add bookmarks to a map.

Layers

• Tiled Layers

  • ArcGIS tiled layer (URL)

  This sample demonstrates how to add an ArcGISTiledLayer as a base layer in a map. The ArcGISTiledLayer comes from an ArcGIS Server sample web service.

  • ArcGIS vector tiled layer (URL)

  This sample demonstrates how to add an ArcVectorGISTiledLayer as a base layer in a map.

• Map Image Layers

  • ArcGIS map image layer (URL)

  This sample demonstrates how to add an ArcGISMapImageLayer as a base layer in a map. The ArcGISMapImageLayer comes from an ArcGIS Server sample web service.

  • Change sublayer visibility

  This sample demonstrates how to show or hide sublayers of a map image layer.

Features

• Feature Layers

  • Feature layer (feature service)

  This sample demonstrates how to show a feature layer on a map using the URL to the service.

  • Change feature layer renderer

  This sample demonstrates how to change renderer for a feature layer. It also shows how to reset the renderer back to the default.

  • Feature layer selection

  This sample demonstrates how to select features in a feature layer by tapping a MapView.

  • Feature layer definition expression

  This sample demonstrates how to apply definition expression to a feature layer for filtering features. It also shows how to reset the definition expression.

  • Create a feature collection layer

  This samples demonstrates how to create a new feature collection with several feature collection tables. The collection is displayed in the map as a feature collection layer.

  • Create a feature collection layer from a portal item

  This samples demonstrates opening a feature collection saved as a portal item.

  • Feature collection layer from query result

  This samples demonstrates how to create a feature collection layer to show a query result from a service feature table.

• Feature Tables

  • Service feature table (cache)

  This sample demonstrates how to use a feature service in on interaction cache mode.

  • Service feature table (no cache)

  This sample demonstrates how to use a feature service in on interaction no cache mode.

  • Service feature table (manual cache)

  This sample demonstrates how to use a feature service in manual cache mode.

  • Feature layer query

  This sample demonstrates how to query a feature layer via feature table.

Display Information

• Graphics Overlays

  • Add graphics (SimpleRenderer)

  This sample demonstrates how you add graphics and set a renderer on a graphic overlays.

  • Identify graphics

  This sample demonstrates how to identify graphics in a graphics overlay. When you tap on a graphic on the map, you will see an alert message displayed.

• Symbology

  • Render simple markers

  This sample adds a point graphic to a graphics overlay symbolized with a red circle specified via a SimpleMarkerSymbol.

  • Render picture markers

  This sample demonstrates how to create picture marker symbols from a URL and embedded resources.

  • Render unique values

  This sample demonstrate how to use a unique value renderer to style different features in a feature layer with different symbols. Features do not have a symbol property for you to set, renderers should be used to define the symbol for features in feature layers. The unique value renderer allows for separate symbols to be used for features that have specific attribute values in a defined field.

Location

• Display Location

  • Display device location

  This sample demonstrates how you can enable location services and switch between different types of auto pan modes.
