• Access the Session and Application data from the client-side JavaScript
• Cache the required results
• Freely use source code
• Add and modify new methods and properties in the framework without modifying any source code
• All the classes support the client-side JavaScript to return data, and DataSet can be used from inside the JavaScript
  Use the HTML controls to access and return data
• Do not need reload the pages and use the event delegate to access data
• Supply only one method for call and dramatically decrease the CPU usage

The Model-View-Controller (MVC) is collection of three separates components: the model, the view, and the controller. The ASP.NET MVC framework provides an alternative way to creating MVC-based application; The MVC-Based applications are different from the ASP.NET Web Forms applications.MVC use all the existing features of ASP.Net Web application. The MVC framework is defined in the System.Web.Mvc namespace.

Understanding Models, Views, and Controllers:

Models for maintaining data and it help to implements the logic for the application. Retrieve and store state in the database, views for displaying all or a portion of the data, helps of applications user interface, and controllers for handling events that affect the model or view (s),and user nitration with the model. in short in an MVC application, the view only displays information; the controller handles and responds to user input and interaction.

The URL difference:

when we are using the ASP.net Web Forms application, then it should be correspondence between URL links and pages. But using MVC there is no correspondence between the address types in address bar and pages.

Creating sitemap:

The easiest way to create a Sitemap by creating an XML file that describes the navigational structure of your website. You can create a new Sitemap in Visual Studio by selecting the menu option Project, Add New Item, and add a Sitemap file.

The <sitemapnode> have the following attributes:

• URL

• Title

• Description

• Resourcekey

• Sitemapfile

e.g.

Web.sitemap

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode 

url=”~/” title=”Home” description=”My Home Page”>
url=”~/Product/Index”
title=”Products”
description=”Our Products” />

url=”~/Service/Index”
title=”Services”
description=”Our Services” />

url=”~/Home/About”
title=”About”
description=”About Us” />

</siteMapNode>
</siteMap>

Web.sitemap Sitemap API:

The Sitemap API is represents the static sitemap class. The access of the static site map class is anywhere within the MVC application. Static sitemap class helps to determine your current presence status. Static class has following properties:

• CurrentNode

• RootNode

• Childnode

• Description

• Nextsibling

• ParentNode etc

Advantages:

• MVC provides test-driven development (TDD) by default.

• Use all existing features of ASP.NET in ASP.NT MVC.

• Support URL naming patters for SEO.

To show image on Crystal Report from database you need to take a image field , save image in it by using the following code

Step 1)

string name = filename.PostedFile.FileName.ToString();//get file name as per your requirment

string strFn = path ;//your image path

FileInfo fiImage = new FileInfo(strFn);

Int32 len =Convert.ToInt32(fiImage.Length);

byte[] m_barrImg = new byte[Convert.ToInt32(len )];

FileStream fs = new FileStream(strFn, FileMode.Open,

FileAccess.Read, FileShare.Read);

int iBytesRead = fs.Read(m_barrImg, 0, Convert.ToInt32(len));

fs.Close();

byte[] imageData = ReadFile(path);

objpro.Logo1=(object)m_barrImg;///your image here save it in database(I m assinging it to property)

objpro.LogoName=Imagename;//image name

Step 2)

///now to show image on crystal report

Place this image field on your report by drag & drop.

Step 3) //where report will show e.g. it may be default.aspx

// I assume you have values in dataset ds;

Int32 Total=0;
