C# - Benefits Of MVC3 - Most Standard Way To Develop A Business
Mar 31, 2011
I am looking to build a web application for users to login and do various things on my website such as depositing money, withdrawal money, creating things that require money etc. I've heard MVC3 Linq and Entity Framework is a good way to build a asp.net c# web application, but I am confused because there are so many ways to build a web application,what is the most standard way to build a website, and what are the benefits of mvc3?

I think i understand the benefit of using themes but I want to be sure I understand correctly. I have previously used css to style my pages. I'm thinking about using themes in my next project. It provides a way to switch between the visual style of web controls and html elements. This could be done by allowing the user to choose a theme that is to their liking.
a) SqlCommand.ExecuteNonQuery is used for update, insert and delete operations.
Besides the fact that by using ExecuteNonQuery instead of ExecuteReader we automatically know there won't be any query results returned, are there some other benefits/reasons why ExecuteNonQuery should be used?
b) Similarly, if we want a database operation to return a single value, we should use ExecuteScalar instead of ExecuteNonquery ,where with the latter result would be returned via SqlParameter. Is there any particular reason why we should prefer ExecuteScalar over ExecuteNonQuery?
I would like to know what does a field timestamp in MSSQL do?I have read a book "ASP_NET_3_5_Social_Networking" and almost all the tabels have a columnt with type "timestamp" in their example app.What is the benefit of timestamp , and why should i use it?

I come from a PHP/Rails background where deploying a website often means FTP/Checkout of the source code in the correct directory on the web server.
However, I've been asked to develop an ASP.NET website and some people have advised me to "Publish" the site instead of copying over the source code directly. Apparently, this converts the codebehind (.cs) files into compiled DLL's etc.
My application does not contain any specific secretive business logic. It's a common shopping cart app. My question is if this is a good idea? How does not making the C# code reside on the server make the app more secure?
In my application at some places we have used ObjectDataSource and at other normal method calls to retrieve data.My question is then what exactly are the benefits of using ObjectDataSource ?In the example below "CODE ONE" makes a call to the Business Layer and then Binds the results to the Grid abd "CODE TWO" is using ObjectDataSource to do the same.Then how is ObjectDataSource better?
SuitableApplicant sa = new SuitableApplicant(); IList<HD.Recruitment.SuitableApplicant> list = new List<HD.Recruitment.SuitableApplicant>(); list = HS.Recruitment.RecruitmentService.GetSuitableAppls(); GridView1.DataSource = list; [code]....
However if I turn off the second one, unobtrusive, I would still expect that client validation would work. However it seems to me that it still posts back fully to the server instead of client side validation only. Is this a bug in MVC3?
I am having a nightmare with getting a Dropdownlist control to work correctly in my MVC application. I am trying to get a set of values out of an enumeration into SelectListItem which I then present to the DropDownList control as its source. The issue is that I can get the thing to render but the selected value is never set and to top it off when the form is posted the value passed across is 0 instead of the actual value. In the View (Razor Code):
HTML4Strict Code: @Html.DropDownList("UserRole", new SelectList(Enum.GetValues(typeof(enumUserRoleUserManagement)), user.UserRole), new { @onchange = "submitForm(" + i + ")" }) in the Controller: Csharp Code: ViewData["RL"] = new SelectList(userActionsModel.GenerateCombo().AsEnumerable(), "Value", "Text"); And Finally in the model: Csharp Code: public IEnumerable<SelectListItem> GenerateCombo() { var enumerationValues = Enum.GetValues(typeof(enumUserRoleUserManagement)); var enumerationNames = Enum.GetNames(typeof(enumUserRoleUserManagement)); List<SelectListItem> list = new List<SelectListItem>(); foreach (var value in Enum.GetValues(typeof(enumUserRoleUserManagement))) { SelectListItem selectList = new SelectListItem { Text = value.ToString(), Value = value.ToString() }; list.Add(selectList); } //SelectList selectList = new SelectList(list); return list;}
I have burned soooo much time on this, I will be indebted to anyone that provides a solution.
I tried upgrading the solution to MVC3 in VS2010 by using an upgrader tool I don't know what it does exactly but it didn't work. My "System.Web.Mvc" is not being recognized in my project. Is there anything specific I should be doing with my web.config? I don't quite understand the underlying details about all the places I should be referencing dll's or what "binding" even means and when I should use it inside the web.config So I have to ask, what is the best method for upgrading to MVC3 and what have you done that works?
In mvc1, we can write an attribute as '[NewPath("mainpage", Controller = "BrowsePdts", Action = "Index")]' before Action for 'mappaththen we can do sth. as 'mappath' in webformI just want a navigate in the top of page , as ' book >> magazine >> fashion 'but what the attribute change to in mvc3?
with creating a submit button?What I need to do is1. Take a parameter from a text field2. Send that parameter to a function to get data when the user clicks submit3. return that data back to the calling page.
I am using mvc 3 unobtrusive concept for validation . It is working fine at client/server side.The problem is that it wont clear until I hit the server again.
Is there any extra code i have to write to clear validation summary ?
We wanted to upgrade our projects from ASP.NET MVC 2 to 3. Most of our tests succeeded, but there are some that fail on ValueProviderFactories.Factories.GetValueProvider(context).
Here is a simple test class that ilustrates the problem.
[TestFixture] public class FailingTest { [Test] public void Test() { var type = typeof(string); // any controller AuthenticationController c = new AuthenticationController(); var httpContext = new Mock<HttpContextBase>(); var context = c.ControllerContext = new ControllerContext(httpContext.Object, new RouteData(), c);
I've recently taken an existing ASP.NET 3.5 web forms application that was upgraded to .NET 4 last year (and has been running fine) and configured it to also run ASP.NET MVC3 following Scott Hanselman's blog post: Integrating ASP.NET MVC 3 into existing upgraded ASP.NET 4 Web Forms applications. It works well and I've successfully begun to introduce views based on Razor and the existing aspx pages continue to work.
The one thing that has stopped working, however, is a custom HttpHandler (our load balancer hits a specific address to ensure the application is available - the handler is for that address). The web.config has always declared the handler in the system.web section like this:
Now we're testing post-MVC3 and I'm getting an exception that reads:
The controller for path '/system/heartbeat.aspx' was not found or does not implement IController. I have defined a RegisterRoutes method in my Global.asax and that method is called from the Application_Start. Within RegisterRoutes I've got the IgnoreRoute declarations from Hanselman's blog:
which I thought was to prevent the Routing system from taking anything with an extension of .aspx. I can reproduce the issue in VS2010 as I debug, and the deployment environment is running IIS 6. What can I do to prevent the Routing system from trying to handle that address so the custom handler can do it's thing?
