2 How to realize a grid view with ASP.NET MVC ?[Top]

The question how to implement the GridView with ASP.NET MVC is often asked on the ASP.NET MVC forums. There are many answers and we pick some popular ones as a FAQ for your reference.

The sample is quite simple and easy to use; first let us check this code below about the definition of ‘PaginatedList’ class.

And now, let us check this code below; the code is used for getting data from database and converting the data to the ‘PaginatedList’,

Here is the view code below; it is generated by the Microsoft Visual Studio 2008(IDE), now we need to change the following code:

To:

If we do not want to change this, we need to implement the IEnumerable interface for PaginatedList by changing the followingcode:

To:

Also we need to assign a route for getting paginated data; here we assign the “News” for this demo code:

And now let’s check the last part, the “News” route; it’s also quite simple.

3 What is difference between ViewData and TempData? [Top]

TempData is used for passing data from one request to other request.

ViewData is used to pass data from controller to view.

Please check this code below,

Here is the T2 view code below:

After test, we cannot see message of “This is ViewData in the action T!” on the T2 view (page).

If you want to know the basic principle, please check these articles,

4 How to choose between ASP.NET Web Forms and MVC? [Top]

The illustration below is enumerating difference between “ASP.NET Web Forms” and “ASP.NET MVC”. It is very helpful for deciding whether to use ASP.NET Web Forms or ASP.NET MVC,

Web Forms

ASP.NET MVC

Tooling/designer

Postbacks

Event driven

HTML forms and viewstate

Controls abstraction

3rd party component model

Rapid development

Declarative syntax

Full control over markup

Lightweight views/no Codebehind

Separation of concerns

Testing/TDD

Pluggable view engines

RESTful

No postbacks

No viewstate

If you are interested in mixing the Web Forms and the MVC, you can check the following website on How do I mix Web Forms and MVC .

5 How to get started on JQuery with MVC? [Top]

For convenience, we take the calendar (datepicker) as example.

Before we do this, we need to download two JavaScript files from the jQuery website, one is called “jquery-1.3.2.min.js” and the other is called “ui.datepicker.js”. Now please refer to the following code,

6 How to perform validation with Data Annotation Validators? [Top]

MVC 2 supports a subset of DataAnnotations. MVC 3 supports the complete set. See How to: Validate Model Data Using DataAnnotations Attributes

The System.ComponentModel.DataAnnotations namespace includes the following validator attributes.

Attribute Function Range Enables you to validate whether the value of a property falls between a specified ranges of values ReqularExpression Enables you to validate whether the value of a property matches a specified regular expression pattern. Required Enables you to mark a property as required. StringLength Enables you to specify a maximum length for a string property. Validation The base class for all validator attributes.

7 How to call action method with JQuery? [Top]

It’s very easy to call the action method by using the jQuery. We just need to call the $.ajax method. You can find the detailed information about the method from jQuery website. The following example gets regions JSON data from server and adds mouseover and mouseout event for each region item. When the mouse is over on an item, the corresponding attractions data will be requested by using jQuery Ajax.

Please refer the following code,

8 How to deploy MVC on IIS? [Top]

The ASP.NET MVC framework depends on ASP.NET Routing to route browser requests to controller actions. In order to take advantage of ASP.NET Routing, you might have to perform additional configuration steps on your web server. It all depends on the version of Internet Information Services (IIS) and the request processing mode for your application. We will focus on two easiest ways to deploy MVC on IIS.

IIS7

We don’t need to perform any special configuration step when using IIS 7.0 in integrated mode.

IIS 6

The method is to create something called a wildcard script map. A wildcard script map enables you to map every request into the ASP.NET framework.

Right-click a website and select Properties

Select the Home Directory tab

Click the Configuration button

Select the Mappings tab

Click the Insert button (see http://static.asp.net/asp.net/images/mvc/08/CS/image008.jpg)

Paste the path to the aspnet_isapi.dll into the Executable field (you can copy this path from the script map for .aspx files)

Uncheck the checkbox labeled Verify that file exists

Click the OK button

IIS5

Right-click your application virtual directory on inetmgr.exe.

Properties->Virtual Directory Tab-> Configuration.

Add a new mapping extension. The extension should be.*, which will be mapped to the Executable C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll, or the appropriate location on your computer (simply copy this from the mapping for .aspx files). On the mapping uncheck "check that file exists".

We can find more resource from the following website.

You can find more information about the validation from the following website.
