How to save value in session in mvc razor page

i want to save EmpID in session, my view code

but EmpID is not saving in session , how to do this

Session["id"]=Model.EmpID;

}

actually it is loop sir, that's why it is taking last id, help me sir how can i get clicked id

this is my code

@helper GetTreeView(List siteMenu, int parentID)

{

foreach (var i in siteMenu.Where(a => a.ReportsTo.Equals(parentID)))

{

@{var submenu = siteMenu.Where(a => a.ReportsTo.Equals(i.EmpID)).Count();}

@if (submenu > 0)

{

}

else

{

}

@i.Name

@**@

@{int id = (int)Session["id"];}

@*@Session["EmpID"][email protected];*@

@*@i.Name*@

@if (submenu > 0)

{

@Treeview.GetTreeView(siteMenu, i.EmpID)

@* Recursive Call for Populate Sub items here*@

am getting error sir, the name TempData does not existing in current context

TempData["id"]=i.EmpID;

}

So you can do one thing save the value in TempDate

session is taking previous inserted value EmpID ,it is not taking clicked EmpID ,

is this not possible to save inside view

then i will suggest you to save value at controller end

thank you for responding sir, value saving in session sir but i want to save that clicked EmpID (<ahref="#@i.EmpID>...) in session
