BingSearchCompletedEventArgs Class
Provides data for the BingSearchDataProvider.SearchCompleted event.
Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v19.1.dll
Declaration
Remarks
An instance of the BingSearchCompletedEventArgs class with appropriate settings is automatically created and passed to the corresponding event’s handler.
Example
This example demonstrates how to manually process received Bing Search request results.
- Create a InformationLayer object and add it to the MapControl.Layers collection. Assign the BingSearchDataProvider object to the InformationLayer.DataProvider property.
- Handle the BingSearchDataProvider.SearchCompleted event. In the event handler, implement the request result processing.
Note
