  Hello,
  On my usercontrol load, I do a call to a WCF service to get some data.
  There is a small delay while doing this, so I thought by using the progressbar while getting the data.
  
  I find examples on the web using WebClient to do this, but I want to use this using a async call eg:
  
  

  proxy.GetMyContextInfoCompleted += (sender2, e2) =>

  {

  C = e2.Result;

  };

  proxy.GetMyContextInfoAsync();

  Any ideas on how to do this ?
  
  Thanks,

  Hello Nicolas,
  
  My apologies with the much delayed answer. So - what type of progress you need to display. Do you have the percent value that you want to display of you want something that will loop endlessly until you tell it to stop?
  
  Did you check the online examples for the RadProgressBar?

  Hi Ravi,
  Typically I do a small increase of the progressbar using a Timer during the Async call. When the async call is completed I update the progressbar to it's max value :-)

  void usrCtrlChangePassword_Loaded(object sender, RoutedEventArgs e)

  {

  grdDetail.Visibility = Visibility.Collapsed;

  rpbProgress.Visibility = Visibility.Visible;

  this.timer = new System.Windows.Threading.DispatcherTimer();

  this.timer.Interval = TimeSpan.FromMilliseconds(10.0);

  this.timer.Tick += new EventHandler(timer_Tick);

  this.timer.Start();

  ADDCInfo.DomainControllerInfoClient DIC = new ADPwdChange.ADDCInfo.DomainControllerInfoClient();

  DIC.getDomainControllersCompleted += new EventHandler<ADPwdChange.ADDCInfo.getDomainControllersCompletedEventArgs>(DIC_getDomainControllersCompleted);

  DIC.getDomainControllersAsync();

  }

  
  

  void timer_Tick(object sender, EventArgs e)

  {

  rpbProgress.Value += 50;

  }

  void DIC_getDomainControllersCompleted(object sender, ADPwdChange.ADDCInfo.getDomainControllersCompletedEventArgs e)

  {

  List<myDomainController> myDCList = new List<myDomainController>();

  myDCList = e.Result;

  rcbDomain.DataContext = myDCList;

  rcbDomain.ItemsSource = myDCList;

  var query = (from p in myDCList where p.Description == "EMEA" select p).FirstOrDefault();

  rcbDomain.SelectedItem= query;

  this.timer.Stop();

  rpbProgress.Value = rpbProgress.Maximum;

  grdDetail.Visibility = Visibility.Visible;

  rpbProgress.Visibility = Visibility.Collapsed;

  }

  Excuse me NS,
  the way you've provided doesn't relate to the lenght of the wcf response size...it's almost a progress without real proportion...am I right?
  Thanks
  Paolo
