Chaging values in grid and BeginInvoke

[Marc Roussel]

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

Hi Marc Roussel,

That sure is a strange behavior. Is it convenient to send us the project so that we can debug it and pinpoint the problem?

Since I would have to send you a huge SQL database because without it the project would never start, I will see if I can make a Repro project for you.  If not, and I can't figure out what's wrong, I'll close this request as not reproductible.

Hi Marc Roussel,

Ok, we will be waiting for a sample application. In the meantime we will once again try to reproduce the problem.

Best wishes,
