jQuery/JavaScript function in MVC not working in production server



I have the following js function that works when I'm in development machine but not in production/hosting server.  I'm thinking that I'm not translating the function for the MVC environment.  Please see below:

In View:

function fillHucDdl(reg) {
                var huclist;
                var items;
                var hucname;
                var jsonPath = $('link[rel="' + reg + '"]').attr("href");

                //get json data from geojson
                $.getJSON(jsonPath, function (data) {
                    huclist = L.geoJson(data, {
                        onEachFeature: function (feature, layer) {
                            hucname =;
                            items += "";

                    //populate dropdownlist with unsorted options

                //sort the options

The dropdownlist is supposed to be populated when the Index.cshtml loads.  It does when I'm in development machine but not in production server.

Appreciate any help.

Multiple tablix and dataset


Hi developers,
I am working on SSRS. There are four tablix on one page, each one has its own dataset (each dataset calls the same stored procedure and a @type parameter is passed which is different for all datasets). I need to show 10 records in each tablix one time and next records should come on next page which will again be showing 10 records in each tablix. Please let me know how can I accomplish this.

Its not necessary to use four tablix, you can provide its alternate if feasible.

Please let me know if further info required.

Handle SignalR disconnects in WPF VB.NET


I'm trying to create a WPF application in VB.NET that receives notifications via SignalR from an API. I've created a basic function to connect to the server, the hub, and consume the data. I'm not sure on how to handle reconnecting to the server once disconnected. Initially I thought I could use Start().ContinueWith() and just have it loop until successful but that neither works nor seems efficient.

Essentially I want the program to be able to handle loss of internet and system hibernation/sleep with grace and reconnect to the signalR hub when possible instead of just having it die.

Private Function CreateSignalR() As Boolean
Dim reTry = True
While reTry
        Dim qryStr As New Dictionary(Of String, String) From {{"phonenumber", My.Settings.UserName.Split("@")(1)}, {"source", "alertApp"}}
        hubConnection = New HubConnection("", qryStr)
        hub = hubConnection.CreateHubProxy("notificationHub")

        hub.[On](Of String)("broadcastMessage", Sub(caller)
                                                    Dispatcher.InvokeAsync(Sub() DisplayAlerts(caller))
                                                End Sub)

        ServicePointManager.DefaultConnectionLimit = 10

        hubConnection.Start().ContinueWith(Sub(task As Task)
                                                If Not task.IsFaulted Then
                                                    reTry = False
                                                    reTry = True
                                                End If
                                            End Sub).Wait()

    Catch ex As Exception
        Return False
    End Try
End While
End Function

Need Help with Asp web Form authentications


Hi I need some input on Forms Authentication. My problem seems to be that the cookie never expires Here is what I have tried:

Created blank web forms project in VS2015. Added this to the root Web.config:


Created a folder called 'Secured' and added a button just as a postback mechanism. Added a web.config to this folder as follows:


Ran it. Waited 5 minutes. Clicked to button on the page. Never got logged out or redirected to login. Checked for cookie in browser. There were 2, '.AspNet.ApplicationCookie' and '__AntiXSRFToken'. Dug deeper. Found where the 'AspNet.ApplicationCookie' was created in Startup.Auth. Altered it to force it to use values listed in web.config as follows:

            app.UseCookieAuthentication(new CookieAuthenticationOptions
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                CookieName = FormsAuthentication.FormsCookieName,
                LoginPath = new PathString("/Account/Login"),
                Provider = new CookieAuthenticationProvider
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity(
                        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))

Ran the application. still no logout and redirect after a postback 5 minutes later. But, Had a Cookie named 'MyCookie' that I could delete and then after postback it would redirect and logout. So I'm thinking the cookie is just not timing out. I tried to check the Cookie Status like this on page postback:

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(this.Request.Url);
            request.CookieContainer = new CookieContainer();
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            foreach (Cookie cook in response.Cookies)
                if (cook.Name == FormsAuthentication.FormsCookieName) { return cook.Expired; }
            return false;

This showed the 'AntiXSRFToken' but not 'MyCookie'. So I'm Assuming 'MyCookie' is not part of the response object. So I needt help. I can force the logout like this:


                // clear authentication cookie
                HttpCookie cookie1 = new HttpCookie(FormsAuthentication.FormsCookieName, "");
                cookie1.HttpOnly = true;
                cookie1.Expires = DateTime.Now.AddYears(-1);

But I still do not know how to check or troubleshoot that the Authentication as actually being timed out before I do this.

Please give me some insight. And suggestions.

Thank you very much.

Passing data from PartialView to its parent View


I want to pass values from a partialView (opened as a modal dialog) to the textbox in the parent view. 

The PartialView

@model IEnumerable

Members List

@foreach (var item in Model) { }
Saving Ac No Member Name Saving Product
Select @item.saving_account_no @item.memberName @item.product_name

The above partial view is called as the popup in the parent view in the following way:

@Html.TextBoxFor(x => x.memberName, new { @class = "form-control medium", @id = "memberName", style="width:80%" })

Now, when the partialView shows as a dialog, i need to do the following:

  • select one of the value from the dialog
  • close the modal after selecting the value
  • display it in the "memberName" textBox.

Help needed ASAP.
Thank you.

Another Update query problem


I have a simple update query that works with a number it it for the registrantID value:

SQLEmail = "UPdate [Registrations] set [Paid] = 'Yes' where [registrantID] =  78"

However if I parameterize it as below

cmd.Parameters.Add("@RegistrantID", OleDb.OleDbType.Numeric, 8).Value = GVSelectedPersonToAddPayment.SelectedRow.Cells(1).Text
        SQLEmail = "UPdate [Registrations] set [Paid] = 'Yes'  where [RegistrantID]=@RegistrantID "

I get the error "Object reference not set to an instance of an object"

Below is a picture of the gridview so you can see where the data is (supposed to be) coming from.


I've been fiddling with this for many hours and can't seem to get it right.
