Symbolize a shapefile

This code sample is available for these platforms:
View Sample on GitHub

Display a shapefile with custom symbology.


Use case

While feature layers come with default symbology, you can apply custom styling to ensure that the content is visible and usable in the context of a specific map.

How it works

  1. Create a ShapefileFeatureTable, providing the path to a shapefile.
  2. Create a FeatureLayer and associate it with the ShapeFileFeatureTable.
  3. Create a SimpleRenderer to override the default symbology. The simple renderer takes a symbol and applies that to all features in a layer.
  4. Apply the renderer to the FeatureLayer by setting the renderer.

Relevant API

  • FeatureLayer
  • ShapefileFeatureTable
  • SimpleFillSymbol
  • SimpleLineSymbol
  • SimpleRenderer

Offline data

This sample downloads the following items from ArcGIS Online automatically:

  • - Shapefiles that cover Aurora Colorado: Public art (points), Bike trails (lines), and Subdivisions (polygons).

About the data

This sample displays a shapefile containing subdivisions in Aurora, CO.

Sample Code

        <esriUI:MapView x:Name="MyMapView" />
        <Border Style="{StaticResource BorderStyle}">
            <Button x:Name="RendererButton"
                    Content="Change renderer"
                    Click="RendererButton_Click" />
