Set the session value in jquery and get that value in Controller?

Question

Is it possible to set the session value in jquery and get that value in controller post method without using any ajax call. I am trying to set one list value to session in jquery

$.session.set('SelectedIdList', selectedIds);

now a want to get these value in Controller post method

public ActionResult SaveTransactions(BusinessViewModel model, string Submit)
{

  model.SelectedIdsList = (string[])Session["SelectedIdList"];

}

Answer 1

I have removed the session from my code I have taken one hidden field and looping that and storing the value with ',' which I am getting that in controller

      $("#hdnSelectedIdList").val("");
      for (var iCount = 0; iCount < SelectedIdList.length; iCount++) {
            $("#hdnSelectedIdList").val($("#hdnSelectedIdList").val() + ',' + SelectedIdList[iCount]);
        }

@Html.HiddenFor(m=>m.hdnSelectedIdList)

and in controller

 model.SelectedIdsList = model.hdnSelectedIdList[0].Split(',');

you cannot set in jquery as Session is a server side thing.

you have to send an ajax call if it is really needed like this:

$.ajax({

                url: '@Url.Action("SetSession","Controller")',
                data {session:1},
                success: function (response) {

                },
                error: function () {

                    alert("Error occured!");

                }

            });

in Action:

[HttpGet]
public Action Result SetSession(string session)
{
Session["key"] = session;
}

You can't set and retrieve like this, since both the data are maintained in a different place. One is in browser and another one is in server.

From $.session Plugin Author

Provides a simple interface into window.sessionStorage while providing limited support for cross protocol requests.

ASP.Net Session

This is basically maintained in the server side.
