The following example shows a callback method named OnSubmitCompleted that accepts a SubmitOperation object as a parameter. It uses this object to check for errors and mark the errors as handled.

private void SaveButton_Click(object sender, RoutedEventArgs e)
{
    _customerContext.SubmitChanges(OnSubmitCompleted, null);
}

private void RejectButton_Click(object sender, RoutedEventArgs e)
{
    _customerContext.RejectChanges();
    CheckChanges();
}

private void CustomerGrid_RowEditEnded(object sender, DataGridRowEditEndedEventArgs e)
{
    CheckChanges();
}

private void CheckChanges()
{
    EntityChangeSet changeSet = _customerContext.EntityContainer.GetChanges();
    ChangeText.Text = changeSet.ToString();

    bool hasChanges = _customerContext.HasChanges;
    SaveButton.IsEnabled = hasChanges;
    RejectButton.IsEnabled = hasChanges;
}

private void OnSubmitCompleted(SubmitOperation so)
{
    if (so.HasError)
    {
        MessageBox.Show(string.Format("Submit Failed: {0}", so.Error.Message));
        so.MarkErrorAsHandled();
    }
    CheckChanges();
}
