Question

// GET: Home

public ActionResult Index()

{

RTC_PRINT_XMLEntities db = new RTC_PRINT_XMLEntities();

ViewBag.District = new SelectList(db.RTC_XML_ADT, "ADT_DIST_CODE", "ADP_DIST_NAME");

return View();

}

public JsonResult GetTalukById(string ID)

{

List<SelectListItem> taluk = new List<SelectListItem>();

var talukList = this.Gettaluk(Convert.ToInt32(ID));

var talukData = talukList.Select(m => new SelectListItem()

{

Text = m.ADT_TALUK_NAME,

Value = m.ADT_TALUK_CODE.ToString(),

});

return Json(talukData, JsonRequestBehavior.AllowGet);

}

public IList<RTC_XML_ADT> Gettaluk(int ADT_DIST_CODE_ID)

{

RTC_PRINT_XMLEntities db = new RTC_PRINT_XMLEntities();

return db.RTC_XML_ADT.Where(m => m.ADT_DIST_CODE == ADT_DIST_CODE_ID).ToList();

}

[HttpPost]

public ActionResult Index(FormCollection formdata)

{

// Get Employee information to insert into Data Base

return RedirectToAction("Index", "Home");

}

}

}

 

 

i am getting error on this line

RTC_PRINT_XMLEntities db = new RTC_PRINT_XMLEntities();

return db.RTC_XML_ADT.Where(m => m.ADT_DIST_CODE == ADT_DIST_CODE_ID).ToList();

 

ADT_DIST_CODE it is howing as a string.

ADT_DIST_CODE_ID it is as int bcoz i put integer there in parameter

how to solve this problem.
