Hello Peter,

loading on demand "freezes" my browser. (Bound to OData - RESTDataSource)

Load on demand is already async. Can you share more details of your igGrid configuration: How many columns do you have? What is your igGridLoadOnDemand.loadTrigger option?

If I look at a grid of your competition (the "Virtualization of remote data" demo), it is very fluent, and the grid and browser pages stays responsive while data is being loaded in the background.

Is it possible with the LoadOnDemand feature?

This is remote virtualization and is not supported with the igGrid Load on Demand feature. However we have it in our backlog and will implement it in a future release.

Can this be fixed? igGrid is advertised as the fasted grid on the market, but this does not seem very fast... (And because IE is the rendering engine in Windows 8, it would affect every Windows Store Apps that uses igGrid, correct?)

As I already noted in your "Bug: LoadOnDemand does not work with (multiple) selections" post the igGrid Load on Demand feature is in CTP stage. If this is proved to be an issue with the feature itself we will fix it. Also we do not recommend you to use it in your production projects. We will work to make it production ready for 14.1 release.
