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,

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;  
        
                    }
