Expression Editor Aggregate Functions Problem

[Eyup]

Hi,

When I use aggregate functions, expression editor doesn't working.
Even I used the example on your help documantation and demos page, the result is the same. (not working :( )

Example on your demos : 
http://demos.telerik.com/silverlight/#ExpressionEditor/FirstLook

Example on your help documantation: 
http://www.telerik.com/help/silverlight/radexpressioneditor-overview.html 
I'm use this formula : 

Average(UnitPrice >= 20 And Discountued = False)

When I use as : 5 + 2 Working
When I use as : Sum(5, 2) Not working


Thanks

Hello,

 Can you write the plain C# version of the expression that will not work for the expression editor?

Kind regards,

Hello,

There is no such Average function in Silverlight. I strongly suggest you to check this article for more info:
