Question

              string popUpHTML="";

                var xx = from Temp in TemplateList
                                where
                                (
                                Temp.TitleID == titleID
                                )
                                select Temp.HTML;

                foreach (var s in xx)
                {
                    popUpHTML =  s.ToString();
                }

The code above is working. The executed linq is supposed to return only one value. Is there any way I can get the result of the above LINQ without a foreach loop. (Sorry I am new to LINQ).

Update: titleID is a unique key in the database, hence only one result is expected.

Right now your query returns an IEnumerable, instead use FirstOrDefault() (or Single() if you are absolutely sure that there always will be exactly one result):

 var popUpHTML = (from Temp in TemplateList
                  where Temp.TitleID == titleID
                  select Temp.HTML).FirstOrDefault();
