After filtering/sorting how to make the pagination not reset to page 1 but stay at current page?

I'm using PagedList library for pagination and also have ordering and filtering. The problem is that after submit of order/filter request the pagination resets to page 1 but I have to keep it at current page? How can this be achieved? I also don't know if this is the right behavior but I was told to it is.
This is my controller:
public class ProductSearchBlockController : BlockController<ProductSearchBlock>
{
private readonly IRepository<Products> _productsRepository;
public ProductSearchBlockController(IRepository<Products> productsRepository)
{
_productsRepository = productsRepository;
}
public override ActionResult Index(ProductSearchBlock currentBlock)
{
if (Session[SessionConstants.Products] == null)
{
Session[SessionConstants.Products] = _productsRepository.All();
}
var sessionProducts = Session[SessionConstants.Products] as IEnumerable<Products>;
var searchString = Request.QueryString.Get(RequestQueryConstants.SearchString);
var orderBy = Request.QueryString.Get(RequestQueryConstants.OrderBy);
var pageNumber = Request.QueryString.Get(RequestQueryConstants.PageNumber);
if (string.IsNullOrEmpty(orderBy))
{
orderBy = "default";
}
if (!string.IsNullOrEmpty(searchString))
{
var result = sessionProducts.Where(p => p.OrganizaitonId.Contains(searchString) ||
p.ProductName.Contains(searchString)).ToList();
Session[SessionConstants.ProductsResult] = result;
}
else
{
var result = sessionProducts.ToList();
Session[SessionConstants.ProductsResult] = result;
}
var productsResult = Session[SessionConstants.ProductsResult] as List<Products>;
productsResult = TableDisplayHelper.OrderedProducts(orderBy, productsResult);
var viewModel = new ProductSearchBlockViewModel();
viewModel.Products = productsResult.ToPagedList(int.Parse(pageNumber), 2);
viewModel.PageNumber = int.Parse(pageNumber);
viewModel.OrderBy = orderBy;
viewModel.FilterBy = searchString;
viewModel.Options = currentBlock.Options;
return PartialView(viewModel);
}
public ActionResult GetTableData(string searchString, string orderBy, int? page)
{
if (searchString == null && orderBy == null)
{
return Redirect(PageHelper.CurrentPageUrl());
}
if (searchString != null)
{
page = 1;
}
int pageNumber = page ?? 1;
var orderByQuery = UriUtil.AddQueryString(PageHelper.CurrentPageUrl(), RequestQueryConstants.OrderBy, orderBy.ToString());
var SearchStringQuery = UriUtil.AddQueryString(orderByQuery, RequestQueryConstants.SearchString, searchString);
var finalUrl = UriUtil.AddQueryString(SearchStringQuery, RequestQueryConstants.PageNumber, pageNumber.ToString());
return Redirect(finalUrl);
}

Found a solution maybe there is a better version but current one works.
Added parameter pageNumber to form and changed form to post:
#using (Html.BeginForm("GetTableData", "ProductSearchBlock", new { pageNumber=Model.PageNumber}, FormMethod.Post))
In controller get the current page number and check if exists set page to current page
public ActionResult GetTableData(string searchString, string orderBy, int? page)
{
var currentPage = Request.QueryString.Get(RequestQueryConstants.PageNumber);
if (searchString == null && orderBy == null)
{
return Redirect(PageHelper.CurrentPageUrl());
}
if(currentPage != null)
{
page = int.Parse(currentPage);
}
var orderByQuery = UriUtil.AddQueryString(PageHelper.CurrentPageUrl(), RequestQueryConstants.OrderBy, orderBy.ToString());
var SearchStringQuery = UriUtil.AddQueryString(orderByQuery, RequestQueryConstants.SearchString, searchString);
var finalUrl = UriUtil.AddQueryString(SearchStringQuery, RequestQueryConstants.PageNumber, page.ToString());
return Redirect(finalUrl);
}

The GET Action is Calling But POST Action is Showing Error.
i am inserting Image in Database.

You are having the error because of the parameter you are passing in the controller HttpPostedFile
HttpPostedFileBase and HttpPostedFile
are definitely not the same.
Change your method to
[HttpPost]
public ActionResult AddSlider(HttpPostedFileBase sliderImage, bcSlider mSlider)
{
//your code here.
}
Notice that I used sliderImage because that was also what you have in your form.
Again Your form, which I don't know if it was a typo error is setting the value of a file-input
<input type="file" name="sliderImage" value=#Model.sliderImage class="custom-file-input" id="exampleInputFile">
You are not supposed to do that.
Again and on lighter note, if it is also not a typo, you don't have any attribute in you class obj.ImageName but you have the below in your insertSlider method
cmd.Parameters.AddWithValue("#SliderImage", obj.ImageName);
For more on HttpPostedFileBase and HttpPostedFile and see here
That's all for now.

The result when I run the project is that I can get the values in the first dropdownlist, but when I select a value I did not get anything back to the second dropdownlist.
I would appreciate any help.
Thanks in advance.
