LocationInformationReceivedEventHandler Delegate
A method that will handle the BingGeocodeDataProvider.LocationInformationReceived event.
Namespace: DevExpress.Xpf.Map
Assembly: DevExpress.Xpf.Map.v18.2.dll
Declaration
public delegate void LocationInformationReceivedEventHandler(
object sender,
LocationInformationReceivedEventArgs e
);
Parameters
Name | Type | Description |
---|---|---|
sender | Object | The event source. |
e | LocationInformationReceivedEventArgs | A LocationInformationReceivedEventArgs object that contains event data. |
Remarks
When creating a LocationInformationReceivedEventHandler
delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
