LocationInformationReceivedEventHandler Delegate

A method that will handle the BingGeocodeDataProvider.LocationInformationReceived event.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v18.2.dll

Declaration

C#

public delegate void LocationInformationReceivedEventHandler(
    object sender,
    LocationInformationReceivedEventArgs e
);

VB.NET

Public Delegate Sub LocationInformationReceivedEventHandler(
    sender As Object,
    e As LocationInformationReceivedEventArgs
)

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.
