Implementing Group By using linq in telerik

[pooja]

Hi,

Can anyone tell how to implement Group By on datatables using linq in telerik (C# Application).
I have written query as follows:

var query = from 

 

 

dataitem in combinedDataTable.AsEnumerable()  

 

 

 

group dataitem by dataitem.Field<string>("IONumber") into r

select new  

 

 

 

{

IONumber = r.Field<

 

string>("IONumber"),
IOName = r.Field<string>("IOName")
}

I am getting error on 'group' saying:
'Telerik.Web.UI.GridDynamicQueryable.GroupBy(System.Linq.IQueryable, string, string, params object[])' is inaccessible due to its protection level

Can anyone suggest how to update this query to work fine? (I am using telerik 2009)

Hello,

How do you use this query? Do you bind it to RadGrid in its NeedDataSource event? Can you send us the source code of a test page (please use  the Format Code Block feature of the editor) that we can debug locally?
