I tried to save and load user settings to xamgrid using persistence framework 11.2

XAML:

<ig:XamGrid AutoGenerateColumns="False" ColumnLayoutHeaderVisibility="Never" Cursor="Hand" Height="680"   Name="dgQResult"  
                    ItemsSource="{Binding  Path=SchedulingQueueResult}"  Margin="8,7,15,8" Width="Auto"    h:HelpProvider.ScreenName="Scheduling Queue" h:HelpProvider.ControlName="dgQResult" Loaded="dgQResult_Loaded" MouseDoubleClick="dgQResult_MouseDoubleClick">
                        <ig:XamGrid.FilteringSettings>

                                            </ig:XamMenuItem.InputBindings>
                                        </ig:XamMenuItem>

</ig:ColumnLayout.Columns>
                            </ig:ColumnLayout>


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

XAML.CS:

On window Closing event: (Saved user settings)

            using (MemoryStream mStream = PersistenceManager.Save(grid, GetStandardGridPersistenceSettings()))
            {
                mStream.Position = 0;
                using (FileStream fs = new FileStream(@"E:\temp\persistence_scheduling.xml", FileMode.OpenOrCreate))
                {
                     mStream.WriteTo(fs);
                }
            }

On Window Loaded Event: (Load Settings):

            if (!System.IO.File.Exists(@"E:\temp\persistence_scheduling.xml"))
                return;

            using (FileStream fs = File.OpenRead(@"E:\temp\persistence_scheduling.xml"))
            {
                PersistenceManager.Load(grid, fs, GetStandardGridPersistenceSettings());
            }

Common Funtions:

public static PersistenceSettings GetStandardGridPersistenceSettings()
        {
            PersistenceSettings settings = new PersistenceSettings();
            settings.SavePersistenceOptions = PersistenceOption.OnlySpecified;

            // Filter menu
            PropertyNamePersistenceInfo prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "RowFiltersCollection";
            settings.PropertySettings.Add(prop);

            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "Columns[].Key";
            settings.PropertySettings.Add(prop);

            // Filter menu
            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "Columns[].FilterColumnSettings";
            settings.PropertySettings.Add(prop);

            // Maybe this is for top filter row?
            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "FilteringSettings";
            settings.PropertySettings.Add(prop);

            // Column sort

            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "SortingSettings";
            settings.PropertySettings.Add(prop);

        
            // Column order?
            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "ColumnMovingSettings";
            settings.PropertySettings.Add(prop);

            // Column width?
            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "ColumnResizingSettings";
            settings.PropertySettings.Add(prop);

            // Visible columns?
            prop = new PropertyNamePersistenceInfo();
            prop.PropertyName = "ColumnChooserSettings";
            settings.PropertySettings.Add(prop);

            return settings;
        }
