Hi,

we are using the XamDataGrid in our application. We see some problems with the loading time of the form when having a lot of records. 

I'm trying to use virtualization with XamDataGrid but I think I'm doing something wrong.

When enabling the virtualization properties it doesnt perform better.

            xamDataGrid.FieldSettings.AllowCellVirtualization = true;

            xamDataGrid.FieldSettings.AllowLabelVirtualization = true;

            xamDataGrid.RecordContainerGenerationMode = Infragistics.Windows.Controls.ItemContainerGenerationMode.Virtualize;

            xamDataGrid.RecordLoadMode = RecordLoadMode.PreloadRecords;

When I embed the XamDataGrid into a VirtualizingStackPanel it does perform well. I gain 50% performance but the grid isn't visible. Why? I don't know yet.

            VirtualizingStackPanel _performancePanel = new VirtualizingStackPanel();

            _performancePanel = new VirtualizingStackPanel();

            Setter setter = new Setter();

            setter.Property = VirtualizingStackPanel.VirtualizationModeProperty;

            setter.Value = VirtualizationMode.Recycling;

            Style style = new Style();

            style.Setters.Add(setter);

            setter.Property = VirtualizingStackPanel.IsVirtualizingProperty;

            setter.Value = true;

            style.Setters.Add(setter);

            xamDataGrid.Style = style;

            _performancePanel.Children.Add(xamDataGrid);

            _performancePanel.IsItemsHost = true;

            this.Content = xamDataGrid;

Can you help me using Virtualization the right way?

With kind regards,

Patrick
