Hi guys,

I have problem... I don't know how to call function(stored procedure) from Entity Data Model in SL application.

I create Silverlight Application in VS2010 (TestSPinSL).

I create ADO.NET Entity Data Model (Model1,edmx).

From database: Northwind.dbo I create NorthwindModel.
Connection settings has been saved in Web.Config file.
In object from database I select only Stored Procedure: Employee Sales by Country.
In Model Browser I choose Add Function Import...

Auto generated code is visible in Model1.Designer.cs

I want to call function/stored procedure (parameters for example: @Beginning_Date = N'1997-08-30', @Ending_Date = N'1998-01-01') and display results from stored procedure in dataGrid1.
