A sample for the required functionality:
public void AddMarker(RadMap Map)
{
SearchRequest r = new SearchRequest();
r.Query = "Paris, France";
r.UserData = new Guid();
bingProvider.SearchCompleted += BingProvider_SearchCompleted;
bingProvider.SearchAsync(r);
}
private void BingProvider_SearchCompleted(object sender, SearchCompletedEventArgs e)
{
//one cannot access the UserData here
}
The request is duplicated with another item in our feedback portal, so we merged both items. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link: https://feedback.telerik.com/Project/154/Feedback/Details/207024-fix-radmap-the-elevationrequest-searchrequest-and-routerequest-should-work-wi The improvement will be included in our next version: Telerik UI for WinForms R1 2017.
