XamGrid Persistance issue StackOverFlow Exception

Ben posted over 12 years ago

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:

 <  ig:XamGrid 
 
 
CellDoubleClicked="AuditXamGrid_CellDoubleClicked"
  FontSize="10"
  FontFamily="Verdana"
  Background="#44FFFFFF"
  HeaderRowHeight="40"
  x:Name="AuditXamGrid"
  Height="Auto" 
 
 
RowHeight="25"
  ItemsSource="{Binding Source={StaticResource ViewModel}, Path=Audits}" 
 
 
AutoGenerateColumns="False" 
 
 
IsAlternateRowsEnabled="True" 
 
 
HorizontalAlignment="Left"
  VerticalAlignment="Top"
  Width="Auto">
   <ig:XamGrid.FilteringSettings>
   <ig:FilteringSettings FilteringScope="ColumnLayout" AllowFiltering="FilterRowTop" AllowFilterRow="Top" IsOnCellActiveEditingEnabled="False" IsMouseActionEditingEnabled="SingleClick" />
   </ig:XamGrid.FilteringSettings> 
　   <!-- Grid Columns -->
   <ig:XamGrid.Columns>
   <ig:TextColumn Key="AuditID" IsReadOnly="True" Visibility="Collapsed"/>

   </ig:XamGrid.Columns>
   </ig:XamGrid>

Hello Ben,

Thank you for your post. I have been looking into it, but it seems like I am missing something about your scenario, so if this is still an issue for you, could you please send me an isolated sample project, where this is reproduced, so I can investigate it further for you.

Looking forward for your reply.

UPDATE:

I got it to save to a byt array, its 3megs which seesms big but atleast it works. Unfortunetly I get the same stack overflow exception when trying to load the filter info, I have the load process on the grid loaded event:

private void AuditXamGrid_Loaded(object sender, RoutedEventArgs e)
        {
            PersistenceSettings gridSettings = new PersistenceSettings();
            //gridSettings.SavePersistenceOptions = PersistenceOption.AllButIgnored;
            gridSettings.LoadPersistenceOptions = PersistenceOption.AllButIgnored;

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

            AuditXamGrid.FilteringSettings.FilteringScope = FilteringScope.ColumnLayout;

            if (ViewModel.AppViewModel.AuditFilterSettings != null)
            {
                MemoryStream memstream = new MemoryStream(ViewModel.AppViewModel.AuditFilterSettings);
                PersistenceManager.Load(AuditXamGrid, memstream, gridSettings);
            }
        }

I have tried everything i can to get this to work, this issue is under a tight time constraint, please help
