    SQL Server sorting, paging and filtering with RadGrid client-side data-binding to WebService

    It is time to post new version of my 1 mil. records demo now with pure SQL Server paging, filtering & sorting. Basically this is very similar to how RadGrid will execute queries internally when you work with LinqDataSource, ObjectDataSource or ANY other DataSourceControl with built-in server paging. Furthermore, RadGrid is smart enough to not request all items in your collection by default if not needed even when you use direct binding via DataSource property. It is important to note that RadGrid will not oblige you to use any special DataSourceControl, class or interface! Conclusion: When you combine pure server-side data operations with pure JSON transfer between client and server, you can...

    Client-side data-binding with RadGrid for ASP.NET AJAX, WebServices and LINQ - Part II

    Today I've spent another ~ 30 minutes to extend RadGrid client-side data binding demo to 1 mil. records from my previous post and now you have caching and filtering included. All data operations are accomplished using famous Dynamic Query Library however you can easily rewrite the demo to use SQL syntax instead if you want. You can check the new example here and download the source from here. Enjoy!

    Client-side data-binding with RadGrid for ASP.NET AJAX, WebServices and LINQ

    As a TRUE ASP.NET AJAX Control you have almost unlimited possibilities with RadGrid for ASP.NET AJAX client-side API. I've spent ~ 30 minutes to create small and powerful demo with client-side data-binding to 1 mil. records using WebService and LINQ. No traditional post back/ajax requests to the same page, no ViewState - just pure JSON. To see the traffic between client and server you can use FireBug, HttpWatch, Fiddler or any other similar tool. Here is a small screenshot from FireBug: Enjoy! [Source code]

    Are you LINQed?

    As you may probably know, since the middle of September last year, RadGrid for ASP.NET provides native and codeless support  for LinqDataSource. You can edit, update, delete and insert records without a single line of code. Furthermore, since the beginning of this year we added codeless hierarchy support - as a result RadGrid for ASP.NET has become the first ASP.NET DataGrid on the market with native LINQ support. With the newly released RadGrid for ASP.NET AJAX we moved our LINQ support to the next level and now the grid will perform all operations like sorting, filtering, paging, etc. using pure LINQ to Objects internally -...
