离开控制器时清除会话
本文关键字:会话 清除 控制器 离开 | 更新日期: 2023-09-27 18:01:54
我在索引页上分页。如果您选择一行并编辑该行并保存记录,那么您将返回到索引,显示之前选择的行和页面。所以这很好。但是,如果您现在转到另一个视图(控制器)并返回到您更新记录的页面,则分页不是从第1页开始,而是从您先前编辑记录的页面开始。那么如何管理你将返回到第1页呢?
我有这个:
[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);
OrderState oState = db.OrderStates.FirstOrDefault(s => s.Code == stateFilter);
if (oState == null)
filter = null;
else {
entities = (IOrderedQueryable<SubmittedForm>)entities.Where(
s => s.Order.OrderState.Code == stateFilter
);
AddFixedNotification(String.Format(Resources.Entity.Environment.FitleredByOrderStateMessage, oState.Title));
hideArchivedOrders = false;
}
}
}
else if (filter.StartsWith("s_")) { // Submitted form state
stateFilter = filter.Substring(2);
SubmittedFormStateEnum sfState;
if (SubmittedFormState.TryCodeToId(stateFilter, out sfState)) {
entities = (IOrderedQueryable<SubmittedForm>)entities.Where(
s => s.SubmittedFormStateId == (int) sfState
&& s.Order.OrderState.Code == OrderState.CompletedCode
);
AddFixedNotification(String.Format(Resources.Entity.Environment.FilteredBySubmittedFormStateMessage, SubmittedFormState.IdToLocalizedName(sfState)));
}
else {
filter = null;
}
}
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(
s => s.Product.Id == productId

AddFixedNotification(String.Format(Resources.Entity.Environment.FilteredByProductMessage, product.Name));

谢谢
你必须在从一个视图到另一个视图时将会话分配给1。那么下次它将返回到第一页。
会话("SubmittedFormpage")= 1;
