I am using TempData[] in MVC application but its not working fine as like that session.
After refresh the page after login page then tempdata have null value please suggest me and
also using in web.config
<sessionState mode="InProc" timeout="10"/>.
TempData is available only for a user’s session, so it persists only till we have read it and gets cleared at the end of an HTTP Request. A scenario that fits the usage of TempData, is when data needs to persist between two requests – a redirect scenario. You can use method Keep to store until next request
TempData.Keep

To fill data from controller, create action:
public ActionResult GetData()
{
// get data from your data source, replace with db call or where to get data
var data = new [] {"sample1", "sample2"};
return Json(data, JsonRequestBehavior.AllowGet);
}
on client when you need data:
$.getJSON(@Url.Action("GetData"), function(data) {
// fill dropdown instead alert
alert(data);
});
See more:
It is supposed to be null after a refresh because TempData is meant only for a single redirect. In your case you must use Session instead.
You can store your data in session.
for example
public static int Points
{
get
{
int points = Convert.ToInt32( HttpContext.Current.Session["PointssessionKey"]);
return points;
}
set
{
HttpContext.Current.Session["PointssessionKey"] = value;
}
}
and also keep in temp data as
TempData.Keep
