When I publish the same app to multiple nodes in Azure and use traffic manager to route the requests evenly, I get the following error in ApplicationInsights and I'm unable to determine the cause:

Get Id of Current User


Hi Devs, 

I´m trying to get the Current User Id so I can make a search in my Users object to find witch user is logged in. I try the following code:

public async Task login(Login login)
            if (ModelState.IsValid)

                var resultadoLogin = await login_Manager.PasswordSignInAsync(login.Username, login.Password, login.LembrarUsuario, false);
                if (resultadoLogin.Succeeded)
                    var current_User= user_Manager.GetUserAsync(HttpContext.User);
                    string current_User_Id = "" + current_User.Id;

                    User user= _context.Users.FirstOrDefault(x => x.Id == current_User_Id );

                    return View("~/Areas/Module/Views/Home/Index.cshtml");
                    ViewBag.login_Error= "Incorrect username or password";
                    return View("~/Areas/Module/Views/Users/Login.cshtml", login);

            return View("~/Areas/Module/Views/Users/Login.cshtml", login);

I noticed that the value of currer_User_Id is always changing when I run the application and the user variable is always returning null because the id doesn´t match.

Best Regards

How to generate a pdf from a List<> and export it to excel



On my mvc application I want to implement a report button that would generate and display a pdf with data on it. The data is stored in a List<> which contains multiple columns, but I only want to display certain column on the report such as (subscriber id, payment date, amount, first and last name), then I would like to display the total of the amount at the bottom (which is not in the list).

I also would like to only display the report in a popup modal (if possible) and not automatically save or create the file to the user's local machine but give them option to either print it or export it to either pdf or excel.

I'm not really sure how to start on this, I've been looking into some tools like iTextSharp, but I couldn't find a good example or documentation the could help me accomplish what I'm trying to do.

NOTE: I'm not using entity framework on my application.

Clickable img in webgrid column only first row works


Hello, I have a webgrid that display an img if data exist. The img is clickable and when clicked it triggers an ajax call. My question is how come it only works on the first row and on the other rows it doesn't even trigger the ajax call var gridColumns = new List();     gridColumns.Add(PaymentGrid.Column(columnName: "WavFile", header: " ", format:@        @if (item.WavFile != null && item.WavFile != "")        { (image)  }        else        { @Html.Raw("(image) ") })); This is my ajax call: I know the data exist on each clickable button because I have the wave file directory displaying on hover. I'm not sure why it only works on the first row. Thank you [...]

ASP.Net Web Site Administration Tool Issue


Greetings all. I hope I am posting this issue to the correct forum.  I had a tough time determining where it belonged, but this seemed reasonable. I am absolutely stuck with a strange issue concerning the ASP.Net Web Site Administration Tool.  First let me detail the provider installation. I created a provider data store via aspnet_regsql.  I then editted web.config for my test web application to reference that database. Next, under IIS, I have created a web application for the tool (.Net 4.0 version) so that I can access via a URL: http://localhost/webadmin/default.aspx?applicationPhysicalPath=C:\Inetpub\wwwroot\Test&applicationUrl=/Test When I browse to the URL, the admistration tool does indeed load.  I can then navigate to all tabs EXCEPT the Security tab.  When I click on that tab, I am meet with an error: There is a problem with your selected data store...  Value cannot be null.  Parameter name: Path If I go to the Provider tab, I can sucessfully test the membership and role providers.  If I run my test application, I can sucessfully register a new user and see that user in the data store.  It just baffles me that I cannot open the Security tab to assign roles.  The really weird thing is that I can configure/run this app on my dev laptop (Windows 7, SQL Server 2008), and the Security tab is not an issue.  But on the web server... Here are a few details about server.  The server is running Windows Server 2003 Enterprise.  ASP.NET version 4.0.30319.0 is installed.  The database server is SQL Server 2005. The provider related sections of the web.config are as follows:               The event log entry for the issue is as follows: Event Type: Error Event Source: ASP.NET 4.0.30319.0 Event Category: None Event ID: 1325 Date: &nbs[...]

If Not IsPostBack with query string


Ispostback is still confused me.

For example, I use query string to pass values from A.aspx to B.aspx like below code.

In B.aspx page load event, do I need add code "If Not IsPostBack Then...End If" ?

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then
Dim sCAMPUS As String = Request.QueryString("OrderName")
Dim sDATE1 As String = Request.QueryString("OrderDate")

End If

End Sub
