Using RadChart with WCF RIA Services

[GEB]

I an using RadChart to show simple counts in chart form.  The data is stored in SQL Server 2008, and I'm looking for the most efficient means of populating counts using RIA Services to access the data.  Because of the large number of records, I would prefer that the counts be calculated on the server.  For example, I would like to retrieve the number of product orders for each month in the past 12 months, then use RadChart to chart the total count for each of the 12 months.  There could be 1000's of orders per month.  Any recommendation?

Hello GEB,

I believe RadChart databinding logic works with any IEnumerable ItemsSource so there is nothing specific about feeding the control with data from RIA service call (i.e. it would be the same as feeding the data to any databound control).

Here are some nice materials on WCF RIA to get you started:

• RIA & Silverlight Clients: http://msdn.microsoft.com/en-us/library/ee707349%28VS.91%29.aspx.
• Brad Abrams series of blog posts: http://blogs.msdn.com/brada/archive/tags/RIAServices/default.aspx.

Greetings,
