Answer 1

The Error is because your query is trying to execute ToString method in db. using AsEnumerable you can tell the query to execute your methods in c#. you can either change your query to

var res = (from results in db.JobSearchAgents
                        where results.SiteID == 110 && results.UserID == sess
                        select result).AsEnumerable().Select(result=>new Agentlist
                        {
                            JobSearchAgentID = results.JobSearchAgentID.ToString(),

                            EmailAddress = results.EmailAddress,
                            Keywords = results.Keywords,


                            Country = results.Country,
                            zipcode = results.ZipCode,
                           miles = results.Miles.ToString()

                        });

Or you can bind your columns to telerik grid without calling ToString method. Telerik grid does not require the data to be in string format. Moreover, if you want data to be displayed in specific format you can call Format method when binding to the grid

columns.Bound(m=>m.Keywords).Foramt("format string");
