如果您離開控制器，清除會話

Question

我在索引頁上有分頁。如果您選擇一行並編輯該行並保存該記錄，則您將返回到索引，其中前一個選定行和頁面可見。所以，這很好:)。但是，如果現在轉到其他視圖（控制器）並返回到更新記錄的頁面，則分頁不是從第1頁開始，而是從先前編輯記錄的頁面開始。因此，如何管理您將返回到第1

我有這樣的：

[Route("sort/{SortColumn}/{SortOrder?}", Name = "Sort-SubmittedForms")] 
[Route("sort/{SortColumn}/{SortOrder?}", Name = "Sort-SubmittedForms")] 
[Route("page/{Page:int}/{SortColumn}/{SortOrder?}", Name = "Paging-SubmittedForms")] 
[Route("search/{SearchString}")] 
[Route()] 
public ActionResult Index(string searchString, string filter, string currentFilter, string sortColumn, string sortOrder, int? page) 
{ 
    IOrderedQueryable<SubmittedForm> entities = db.FilteredSubmittedForms; 

    if (searchString != null) page = 1; else searchString = currentFilter; 
    if (page == null && Session["SubmittedFormpage"] != null) 
     page = (int)Session["SubmittedFormpage"]; 

    bool isHandler = ApplicationUserManager.IsProductHandler(this.User); 

    bool hideArchivedOrders = true; 

    if (filter != null) { 
     int productId = 0; 
     string stateFilter = null; 
     if (filter.StartsWith("o_")) { // Order state 
      if (isHandler) 
       filter = null; 
      else { 
       stateFilter = filter.Substring(2);

      } 
     } 
     else if (int.TryParse(filter, out productId) && productId > 0) { 
      Product product = db.Products.Find(productId); 
      if (product == null) productId = 0; 
      else { 
       entities = (IOrderedQueryable<SubmittedForm>)entities.Where(

你必須同時從一個視圖到另一個視圖去會話分配1。那麼下次它會返回到第一頁。

Session [「SubmittedFormpage」] = 1;
