Provides map images from the Web Map Service Provider.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v19.2.dll

Declaration

C#

public class WmsDataProvider :
    FullRequestedImageDataProvider,
    IWmsContextProvider,
    IFullRequestedContextProvider,
    IUnitConverterProvider

VB.NET

Public Class WmsDataProvider
    Inherits FullRequestedImageDataProvider
    Implements IWmsContextProvider,
               IFullRequestedContextProvider,
               IUnitConverterProvider

Example

This example demonstrates how to obtain a collection of layers supported by the Web Map Service.

To do this, use the WmsDataProvider.ResponseCapabilities event arguments to obtain the CapabilitiesResponsedEventArgs.Layers collection.
