MVC 4 Paging Searching - asp.net-mvc

Question

I have applied search method in my project but , I have also Action index()
and getting erorr. (The current request for action 'Index' on controller type 'AdultLiteracyTeachersController' is ambiguous between the following action methods:)
public ViewResult Index(string searchstring, string currentFilter, int? page)
{
if (searchstring != null)
{
page = 1;
}
else
{
searchstring = currentFilter;
}
ViewBag.CurrentFilter = searchstring;
var teachers = from r in db.AdulLiteracyTeachers select r;
if (!string.IsNullOrEmpty(searchstring))
{
teachers = teachers.Where(r => r.ALTName.ToUpper().Contains(searchstring.ToUpper()));
}
teachers = teachers.OrderBy(r => r.ALTName);
int pagesize = 10;
int pageNo = (page ?? 1);
return View(teachers.ToPagedList(pageNo, pagesize));
}
The other ActionResult.index()
public ActionResult Index()
{
var adulliteracyteachers = db.AdulLiteracyTeachers.Include(a => a.District);
return View(adulliteracyteachers.ToList());
}
Action result is used for calling all data how can I aplly in single index ?

Answer 1

Combine them:
public ViewResult Index(string searchstring, string currentFilter, int? page)
{
if (searchString == null && currentFilter == null && !page.HasValue)
{
// No parameters
var adulliteracyteachers = db.AdulLiteracyTeachers.Include(a => a.District);
return View(adulliteracyteachers.ToList());
}
// Regular code here down
if (searchstring != null)
{
page = 1;
}
else
{
searchstring = currentFilter;
}
ViewBag.CurrentFilter = searchstring;
var teachers = from r in db.AdulLiteracyTeachers select r;
if (!string.IsNullOrEmpty(searchstring))
{
teachers = teachers.Where(r => r.ALTName.ToUpper().Contains(searchstring.ToUpper()));
}
teachers = teachers.OrderBy(r => r.ALTName);
int pagesize = 10;
int pageNo = (page ?? 1);
return View(teachers.ToPagedList(pageNo, pagesize));
}
