I have an application that was implemented using the Telerik RadGridView control and Caliburn.Micro MVVM framework. Because of some performance problems, I needed to implement the Telerik VirtualQueryableCollectionView in place of the direct control-to-ObservableCollection binding that was being used. The original code has the ItemsSouce property of the RadGridView was bound to the Prices property of the view model. I had to eliminate that binding and this in the code-behind:
public PricingView(PricingViewModel vm)
{
InitializeComponent();
var dataView = new VirtualQueryableCollectionView()
{ LoadSize=20, VirtualItemCount = vm.Prices.Count };
dataView.ItemsLoading += (sender, e) =>
{
var view = sender as VirtualQueryableCollectionView;
if (dataView != null)
{
view.Load(e.StartIndex, vm.Prices.Skip(e.StartIndex).Take(e.ItemCount));
}
};
this.PricesGridView.ItemsSource = dataView;
}
The biggest problem with this is the parameter that is required in the constructor. Is there a better way to get a reference
to the ViewModel? Or perhaps a better way to do the whole thing?
Thanks
