Hi,

When coming back for a call to WCF, I populate the grid and then after I'm changing some values in it. The values appears 50% of the time visually but 100% of the time the value is really changed behind the scene in the collection and in the grid but visually it appears only 50% of the time.

Now I tried with BeginInvoke and it's not appearing 80% of the time. It's better but still not correct.
Where do I have to put my code to make 100% sure I will see my change.

Here's the complete call back :

    
            private void _Proxy_GetTimesCompleted(object sender, GetTimesCompletedEventArgs e)  
        
            {  
        
                if (e.Result.Count > 0)  
        
                    if (e.Result[0].Message != null)  
        
                        if (e.Result[0].Message != "")  
        
                        {  
        
                            Generics.ShowCursor(this, false, false);  
        
                            throw new Exception(e.Result[0].Message);  
        
                        }  
        
                _Times = e.Result;  
        
                rgvTimes.ItemsSource = _Times;  
        
                SetTimesGrid(); // Adding the columns to the grid  
        
                if (SelectedJob != null && SelectedJob.JobStatus == GetJobStatusCode(JOBSTATUS.CREATION_CP))  
        
                {  
        
                    SelectedJob.JobStatus = GetJobStatusCode(JOBSTATUS.INSTPROD_IP);  
        
                    SelectedJob.JobLineType = GetJobStatusCode(JOBSTATUS.PRODUCTION_P);  
        
                    SelectedJob.JobActive = true;  
        
                    //---------------------------------------------------------  
        
                    // Sometimes I have to use the Dispatcher because it does not the job on the Grid  
        
                    // and in this case here, the time was properly set but not visible even with the Rebind

                    // The PunchTeam is a method that just change some values in the collection and rebind the grid  
        
                    //---------------------------------------------------------  
        
                    this.Dispatcher.BeginInvoke(() => PunchTeam(PUNCHTYPE.IN));  
        
                    _Proxy.UpdateJobAsync(SecretKey, SelectedJob);  
        
                }  
        
                SetStartStopButtonState();  
        
                Generics.ShowCursor(this, false, false);  
        
            }

PunchTeam is the method that changes some values in the collection and Rebind() the grid.
I tried to put the code in DataLoaded event with the same problem.

Thank you
