Namespace: DevExpress.Xpf.Map

public delegate void LocationInformationReceivedEventHandler(
object sender,
LocationInformationReceivedEventArgs e
);
Public Delegate Sub LocationInformationReceivedEventHandler(
sender As Object,
e As LocationInformationReceivedEventArgs
)
Parameters
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.
Example
<dxm:BingGeocodeDataProvider x:Name="geocodeProvider" ProcessMouseEvents="False"
BingKey="{Binding Source={StaticResource YourBingKey}}"
LocationInformationReceived="geocodeProvider_LocationInformationReceived"/>
private void geocodeProvider_LocationInformationReceived(object sender, LocationInformationReceivedEventArgs e) {
GeocodeRequestResult result = e.Result;
StringBuilder resultList = new StringBuilder("");
resultList.Append(String.Format("Status: {0}\n", result.ResultCode));
resultList.Append(String.Format("Fault reason: {0}\n", result.FaultReason));
resultList.Append(String.Format("______________________________\n"));
if (result.ResultCode != RequestResultCode.Success) {
tbResults.Text = resultList.ToString();
return;
}
int resCounter = 1;
foreach (LocationInformation locations in result.Locations) {
resultList.Append(String.Format("Request Result {0}:\n", resCounter));
resultList.Append(String.Format("Display Name: {0}\n", locations.DisplayName));
