Loading animation when using VirtualQueryableCollectionView

[Wenrong]

Is there a way to instruct the RadGridView to display loading animation while it is fetching data from the bound VirtualQueryableCollectionView(query) { LoadSize = 10 }?

Probably not when scrolling, but when it's loading the initial data...

I have tried DataLoadMode="Asynchronous" but that doesn't seem to do the trick...

Hello,

 DataLoadMode="Asynchronous"  is related to the the entire collection loading in the background thread while VirtualQueryableCollectionView will load/access items record by record and the grid will not know anything about this. 

Kind regards,

I changed database binding from VirtualQueryableCollectionView to a simple List like this:

public List<Item> Items
{
    get
    {
        Thread.Sleep(3000);
        return new List<Item>(odataquery);
    }
}

But still don't see the loading animation...
