InformationLayer Class

A layer that is used to display additional information above the map.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v21.2.dll


public class InformationLayer :


The information layer allows you to place GIS elements (e.g., a search panel) above a map.

GIS elements can be connected to the data provider by assigning the InformationLayer.DataProvider property to the corresponding data provider type. After that, you can send and display the information requests from this provider on a GIS element.

For more information on information layer, see the Layers topic.


This example demonstrates how to allow users to search for a specific place on a map using the Search panel.

To enable searching in the map control, do the following.

The Search panel appears automatically (since the BingSearchDataProvider.ShowSearchPanel property value is true by default).


If you run the application, and see a window with the following error message: ”The specified Bing Maps key is invalid. To create a developer account, refer to”, refer to the following tutorial: How to: Get a Bing Maps Key.
