I need to be able to filter grid items similar to how it is done in the ASP.NET AJAX controls where you can setup filtering for each column. I have made the Telerik ASP.NET Ajax Grid control to be 100% client side with virtual paging / filtering using Linq filtering on the client to server ajax calls. The Kendo Grid I think is almost there. I just need to be able to do filtering and then I think I will have the functionality that I have now.
