What you are trying to do is not a good practice. Why do you want to change the dropdown list after user selected it. Are you making things harder while there might an easier solution for you actually need ???

Hi,
I am after some guidance how to incorporate angularjs into this project. I am looking for a nicer way of writing the data to the table. Any help would be most appreciated.
public class RaceDayDisplayController : ApiControllerWithHub<RaceDayDisplayHub>
{
[HttpPost]
[Route("api/DoSomething")]
public HttpResponseMessage DoSomething(Rootobject model)
{
Hub.Clients.All.LastSectional(model.sectionTimes[0].runners);
}
}
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

Hi All,
I have an ASP.Net Web Form Application and I have a button called "Open Cash Drawer" in the form, and I want when click the button call a windows form application on the client PC to open the cash drawer.
I do some search on the Internet and the result is to use "Register URI Scheme" to interact web and windows application together .
Please let me know how to do that, and give me any sample code if possible.
Thanks Alot

True, that is the only possible solution here.
Also, apart from that, you also need to make sure that your desktop application is also available on the client device, installed and listening for that URL or URI, or the protocol — you can check how Torrent clients, Skype client etc work. They use the same methods to listen to a button click, and then the browser itself starts the default application for that URL (uTorrent for the magnet links, Skype for call links, your email client for mailto links etc). This article covers everything you need to do in order to register that URI in the registry, Registering an Application to a URI Scheme (Windows).
Rest of the stuff is not at all complex, the only thing is to have the client install your desktop application, if they trust you, they will, if they do not then you need to earn some trust.

Could someone please explain what is happening in the following code?
Private Sub BindListView()
Dim constr As String = ConfigurationManager.ConnectionStrings("Tokens4UDissertationSite").ConnectionString
Using con As New SqlConnection(constr)
Using cmd As New SqlCommand()
cmd.CommandText = "SELECT ProductID, ProductName, ProductDescription, ProdImage, CustomerID, Cost FROM Product ORDER BY ProductID DESC"
cmd.Connection = con
Using sda As New SqlDataAdapter(cmd)
Dim dt As New DataTable()
sda.Fill(dt)
ListView2.DataSource = dt
ListView2.DataBind()
End Using
End Using
End Using
End Sub

That one is a simple code, that connects to a database and reads the records, to show them in a listview.
A few things to understand here include,
1) SqlConnection
2) DataTable
3) ListView
If you can understand this, and have a basic understanding of how a database works, then you would easily get to the point where you can know what this program is doing. Secondly, if you ever stumble upon such a problem, always try to Google for the objects provided here, such as, SqlConnection etc. Google would provide you with some useful information about them, through MSDN, or through any other popular channel.

+5. Great explanation.

Hello, please someone help me how to do this exercise step by step.
Regards
Exercise – ASP.NET MVC Web Application
Create an ASP.NET MVC web application to display customer orders.
You must use the Model-View-Controller design pattern using Visual Studio 20115 and C# .NET.
For the UI, create two Views and the necessary Controllers that return the Views; one View for showing customer information and the other for showing the orders.
The orders View should be the default View that displays all the fields related to the customer order, see the order table below but remember to show the customer name rather than the CustomerId.
For the customer Views, create 4 Views to Create, Read, Update and Delete all fields for a customer.
The model must contain the following two entities, whose data is persisted to a SQL Server database or file. CustomerId is the filed that links to order table with the Id field of the customer table
SCREEN HOW TABLES MUST BE:

Hi,
I want to develop an ASP.Net Application (Financial and Accounting System), and this application must connect to many devices that connected to the client PC such as Cash-Drawer, POS Printer, Checks Reader, Scanners, and any device that can be used for this system.
My Question is: is it possible to deal and connect with all of this devices using the asp.net classic web form application.
Or to do the best I must create the application as a windows Forms Application.
Thanks a lot

A windows form will generally have more rights to access the local pc than a web app will so that would likely be better, in my opinion.

Thank you, do you know any library that we can use it to connect to this devices or how to do this.
Thank You

I don't. Each device will have it's own way of communicating. Not sure if there is any library to help with that.

You have already posted this question in ASPNET forum.
You have applied regular expression validator to validate CARD Number which looks to be working. When you check did you input correct card number satisfying your regular expression? If not you will get the error even though you input 'Anything' not satisfying regular expression.
I tried something random number as ='9656385485477444' and did not get any issue

You can filter the results. MSDN has a list of the columns and their use

i found it...here it is

when we develop report with ssrs then we can bind ssrs with sql server store procedure or c# data set. suppose sql server store procedure return 10,00,000 data and configure ssrs to show 50 data at a time in page. so my question is ssrs will fetch 10,00,000 data and store in memory but display 50 data at a time ?
if this is true then report performance will be slower and huge memory will be required and block due to large data stored. so please tell me if anyone know how ssrs handle large data.
how developer should develop ssrs when large data will be there. thanks

I have a global.asax file, namespace being the project name, and I did check the spelling
in the Global.asax, I have a function called GetWebsiteName(), and in the view I call it.
I did some large project changes yesterday, and I broke things in the program, but have fixed all but this issue.
I'm just scratching my head on this one! I tried searching for anwsers but haven't found anything similar.
namespace coastEnviromental
{
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BinaryDataConfig.RegisterGlobalBinaries();
}
protected void Session_Start(Object sender, EventArgs e)
{
Session["init"] = 0;
}
public static string GetWebsiteName()
{
string pValue = Properties.Settings.Default.WebsiteName;
return pValue;
}
And in the View, the MvcApplication has a red line under it saying that I'm missing an assembly reference.
@{
string websiteName = MvcApplication.GetWebsiteName();
}
If it ain't broke don't fix it
