I am trying to persist filters but having no luck.

on cell double click it redirects to a detail page, when navigating back i would like to keep the filters in which the user had prior to leaving the page.

 I have this event i am calling on double click:

private void AuditXamGrid_CellDoubleClicked(object sender, Infragistics.Controls.Grids.CellClickedEventArgs e)
        {
            var TheCell = AuditXamGrid.ActiveCell;
            if (TheCell == null) return;

            var data = TheCell.Row.Data;

            if (data is GetSummaryAuditResult)
            {
                var rowdata = data as GetSummaryAuditResult;

                PersistenceSettings gridSettings = new PersistenceSettings();
                gridSettings.SavePersistenceOptions = PersistenceOption.OnlySpecified;

                PropertyNamePersistenceInfo pnpi = new PropertyNamePersistenceInfo();
                pnpi.PropertyName = "Columns[].FilterColumnSettings";
                pnpi.Options = PropertyNamePersistenceOptions.Contains;
                gridSettings.PropertySettings.Add(pnpi);


                MemoryStream ms;
                ms = PersistenceManager.Save(AuditXamGrid, gridSettings);

                ViewModel.AppViewModel.AuditFilterSettings = ms.ToArray();

                NavigationService.Navigate(new Uri("/AuditDetails?AuditID=" + rowdata.AuditID 
                                                                    + "&MatchID=" + rowdata.MatchID 
                                                                    + "&PackageID=" + rowdata.PackageID
                                                                    + "&Perner=" + rowdata.Perner, UriKind.Relative));
            }
        }

When is gets to the saving the setting i get a stack over flow exception and i just cant get around it.

here is my Grid:
