RadGrid and WCF

[Igor]

Hi,

I am considering Telerik for a project that has to communicate with external WCF service. What is the best approach in terms of performance to bind data from the service to RadGrid? External web service provides methods like "List<Document> GetDocuments()".

Am I able to use direct "Client-Side Binding" as described at http://demos.telerik.com/aspnet-ajax/grid/examples/clientbinding/defaultcs.aspx or should I call the service and bind data "OnNeedDataSource"?

Thanks,

Igor

Hello Igor,

Choosing the approach deepens on your requirements.
In the worst case when a grid is bound to huge data in the web server the RadGrid gives great performance. However working with web services and JSON increase the performance:     http://blogs.telerik.com/VladimirEnchev/Posts/08-05-23/SQL_Server_sorting_paging_and_filtering_with_RadGrid_client-side_data-binding_to_WebService.aspx?ReturnURL=%2fVladimirEnchev%2fPosts.aspx
 However in this case there is some scenarios which is not supported and the RadGrid customization is more difficult.  More information about client side binding you could find here:
http://www.telerik.com/help/aspnet-ajax/grid-client-side-binding.html

If you have additional logic which needs to be applied over a received data from the web service the advanced databinding using NeedDataSource is better choice. Also in this case you have more flexibility for customizing the RadGrid and the showed data into it.

I hope this helps.

Kind regards,
