Hi,

I am working on search functionality module in which i have to pass parameters through query string.But the query string must be generated dynamically based on the options selected by the user. (like user may select platform=asp.net, programming language=c#,location=us etc..)

I have worked on static query string but not on generating string during run time.
It would be helpful for me if any friend help in achieving the above functionality.

Thanks,

Vasanth

try this

SQL

create dynamic query like that
and pass one parameter to database
Collapse
if (InterviewCategoryId == 0)
           {
               if (DateTo == "" && SearchByName == "" && DateFrom != "")
               {
                   Query += " ";
               }
               else if (DateTo != "" && DateFrom == "" && SearchByName == "")
               {
                   Query += " ";
               }
               else if (DateTo == "" && DateFrom == "" && SearchByName != "")
               {
                   Query += " ";
               }
               else if (DateTo != "" && DateFrom != "" && SearchByName != "")
               {
                   Query += "";
               }
               else
               {
                   Query += "";
               }

pass it to the DataBase as one Parameter;
Obj.fn_GetSearcgCandidatesResult(Query);
