A label won't update if dropdown is inside updatepanel


The SelectedIndexChanged event fires properly and execute the code without any errors. The last thing I do in it is to set the value of a label which isn't updated. If I move the TD element inside updatepanel then it will refresh the label but screen flashes and I am trying to avoid the screen flash.



The code below does update the label:


The only code I have in ddlF1 and ddlF2's SelectIndexChange is  lblTemp = "My Test";

Authorize attribute not working


I have an ASP.NET MVC (version 5.2.3) web application using Individual User Accounts and .NET Framework 4.5.1.  For some reason the Authorize attribute on my controller classes no longer works.  I can log into the website as a user who is NOT in role Admin, Supervisor or WorkcenterA and it still allows me to access the Create method inside the WorkcenterA controller.  It shouldn't allow this.  If I set a breakpoint on the WorkcenterA controller Create method User.IsInRole("Admin") = false and User.IsInRole("Supervisor") = false and User.IsInRole("WorkcenterA") = false so why did it allow the Create page to be accessed?  It's like the Authorize attribute does absolutely nothing.  Can somebody give me a hint as to how I can fix it?  I have researched this issue on Google but all suggestions have failed to resolve my problem.

[Authorize(Roles = "Admin, Supervisor, WorkcenterA")]
public class WorkcenterAController: HelperController

Select Query Breaks when Choosing a different DropDown Selection


Hello, I have created GridView to retrieve comments entered by users. I have provided drop down boxes to filter data: Year, Month, Tab, Section, Order. When users filter it first by year then any other drop down selection, it works fine. When users try to filter the Gridview data by Month, Tab, or Section first I get the error below. ORA-00933: SQL command not properly ended Here is the code: aspx page: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Comments.aspx.cs" Inherits="ChngMgmt_Comments_and_Legends.Comments" %>

why Most of the time ajax success function doesn't work in MVC?


In my project, I've used datatable for CRUD operation.but I have a problem most of the time didn't work success function, of course, I saw my network tab I received {status:true} but datatable didn't reload and I redirected to the blank fact, if I want to add a record my record will add but it redirects to the blank page. also, I've added alert function into success function it didn't fire.this problem is in Create, Delete, Edit operation. I've read a lot of links on the internet but they couldn't help me. // GET: Admin/Users/Delete/5 public ActionResult Delete(string id) { if (id == null) { return new HttpStatusCodeResult(HttpStatusCode.BadRequest); } User user = db.User.Find(id); UserViewModel userViewModel=new UserViewModel(); userViewModel.UserId = user.Id; userViewModel.UserName = user.UserName; userViewModel.FirstName = user.FirstName; userViewModel.LastName = user.LastName; userViewModel.Email = user.Email; userViewModel.IsActive = user.IsActive; userViewModel.Gender = user.Gender; userViewModel.PhoneNumber = user.PhoneNumber; userViewModel.Address = user.Address; if (user == null) { return HttpNotFound(); } return PartialView(userViewModel); } // POST: Admin/Users/Delete/5 [HttpPost, ActionName("Delete")] [ValidateAntiForgeryToken] public ActionResult DeleteConfirmed(string id) { bool status=false; User user = db.User.Find(id); db.User.Remove(user); db.SaveChanges(); return Json(new { status = true }, JsonRequestBehavior.AllowGet); } ========================== @model IEnumerable @{ ViewBag.Title = "مدیریت کاربران"; } @*

Drop Down Boxes do not automatically refresh data


Hello I have a simple one page CRUD app. Users can add comments and view comments in Grid View on same page. I have provided them with dropdown boxes to filter data as well. The issue is when users enter new data to the database, the dropdown boxes do not include that information. For example if a user entered a comment for year = 2018, month = July, the Year 2018 does not show if it was not previously added by some other user. Where do I need to fix my code? ASPX PAGE: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Comments.aspx.cs" Inherits="ChngMgmt_Comments_and_Legends.Comments" %>

New in WCF


Getting this error at the time of compiling WCF service:

"Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata."

The service encountered an error:

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior contract: ----> ..... bla, bla....

My service is:

namespace MyService
    using TIN.DataMobile;       

    public interface ITIN_EXT_ServiceMobile
        string findContact(int eid);

        String addUser(string uID);

        Mob_AddSessionOut Mob_AddSession(Mob_AddSessionIn pInput);

The issue is in the last service because all is fine with the first two service.


public class Mob_AddSessionOut
        public String Auth_token { get; set; }
        public Boolean Transaction_moviment { get; set; }
        public TIN.DataAccessLayer.Gen_StatusProcess StatusProcess { get; set; }    


What am I doing wrong?


The resource object with key 'Login' was not found. ( and azure)


I publish web app and database to azure, and I can link my local to azure database. the web app is working on my local. but I run, I got the error:

The resource object with key 'Login' was not found.

I open vs2013 and I can find the key in "" and "Resource.zh.resx" on "App_GlobalResources" folder.

I am not sure what is going on (the point is the web is working on my local when I link to azure database).

I can find some info on "app service editor":

in "bin", I can find "resources.dll" file in "zh" only, it means I miss "us" file?

thanks for any idea.

data is null when ajax call reaches controller



I'm trying to do an ajax call to my MVC controller but the data is coming through null.

Here is my ajax call:

var projectId = store.get('filterProjectId');
var data = ra.reportConfigPage.ReportJsonParsed;
var equipmentType = $("#EquipmentTypeTextbox").val();
var dataWithToken = ra.AddVerificationTokenToData({
projectID: projectId,
data: data,
equipmentType: equipmentType

url: "ReportConfig/SubmitData",
data: dataWithToken,
traditional: true
.done(function (data)
.fail(function (jqXhr, textStatus, errorThrown)

And here's SubmitData(...):

public JsonResult SubmitData(int projectId, Top3AndReportCard data = null, string equipmentType = null)

data is not null in the Javascript. When it gets to SubmitData(...) however, it is null.

Can anyone see what's wrong? Thanks.
