Hello,
I'm trying use domain data source with RadGrid in ASP.NET 4.0 project (by this demo http://demos.telerik.com/aspnet-ajax/grid/examples/programming/domaindatasource/defaultcs.aspx). I'm using LinqToEntitiesDomainService (EntityFramework).
I'm getting following error:
Server Error in '/' Application.
Exception Details: System.NotSupportedException: The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'.
Source Error:
Stack Trace:
Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.237
Could you help me please?
Thank you
