you should post code better answer think understand asking. accomplish use c# webgrid in html queries 3 tables this:

@{ var db=database.open("contracts"); var selectcommand = "select requests.*, contractors.agency+'/'"+                     "+contractors.firstname+' '+contractors.lastname contractor,programs.division "+                     "from requests, contractors, programs "+                     "where contractnumber not null "+                     "and contractnumber <> '' "+                     "and scannedcontractdate not null "+                     "and amendmentcount = 0 "+                     "and contractors.id = requests.contractorid "+                     "and requests.programid = programs.id ";  } <h2>page title</h2> <div>@grid.gethtml( tablestyle: "grid",             headerstyle: "head",             alternatingrowstyle: "alt",             columns: grid.columns(             grid.column("division"),             grid.column("contractnumber", header:"contract number"),             grid.column("contractor"),             grid.column("startdate", header:"start date", cansort: true),             grid.column("enddate", header:"end date", cansort: true),             grid.column("amount"),             grid.column("scannedcontractdate", header:"contract date", cansort: true),             grid.column("maxamend", header:"amendments")            ) )          </div>

i hope answers question!
