Display draw status

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

Get the draw status of your map view or scene view to know when all layers in the map or scene have finished drawing.


Use case

You may want to display a loading indicator while layers are loading, which could then be removed on DrawStatus.Completed.

How to use the sample

Pan and zoom to see drawing status changes.

How it works

  1. Create a MapView and subscribe to the DrawStatusChanged event.
  2. Inspect the draw status property in the event handler to determine draw status.

  • Map
  • DrawStatus
  • MapView

Sample Code

        <esriUI:MapView x:Name="MyMapView" />
        <Border BorderBrush="Black" BorderThickness="1" Background="White"
                VerticalAlignment="Top" HorizontalAlignment="Right"
                Margin="30" Padding="20" Width="300">
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
                <TextBlock x:Name="StatusDisplay"
                           FontWeight="SemiBold" />
                <ProgressRing x:Name="ActivityIndicator"
                              IsActive="True" />
