I want to use DataGridControl in Virtual mode in my application.As a datasource I used my own collection which implented such interfaces as IList, ICollectionView. But when I set DataGridControl.ItemsSource property to my collection it began read all available records(about 5.000.000).

Could you explain how to use your DataGridControl in virtual mode and load records on demand?

Thanks a lot.

Hi Vadym,

Thank you for your update.

At present we are not have support for OnDemand loading, our virtualization is on rendering the cells based on the view port. Initially the Grid will read all the records to create the view and then it will render the cells than are currently in view, when you scroll the Grid it will render the new cells that enters the view port. Only the Cells that are currently in view will get render, in this way the virtualization will work on the GridDataControl.
