    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...

    RadControls and ASP.NET Dynamic Data - Update

    UPDATE: You can download the latest Dynamic Data bits from here. We have been working for some time to integrate RadGrid in the ListDetails page template. I am pleased to announce that this is now a fact. You can use a modified version of ListDetails.aspx bundled with RadGrid. See for yourself: You can download the bits from here. They are tested with the latest Dynamic Data bits which you can grab from here. I would like to thank David Ebbo for his continuous support and help. Also a big thank you to my colleague Vlad (our local RadGrid expert) who provided invaluable assistance with...

    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]
