ESRI.ArcGIS.Client.Tasks Namespace > IdentifyParameters Class : LayerOption Property

Specifies which method to use when using Identify. "Top": Only the topmost visible layer is identified. "Visible": All visible layers are identified. "All": All layers are identified, even if they are not visible. Performance note: if your service has many layers, a request using "All" will not perform well. A visible layer means you can see it in the map at the current extent. If a layer is turned off or not in range based on its scale dependency settings, it cannot be identified. To idenfity sub-layers that are not visible in the default map service definition, you may need to use the "All" option to return results.
