ASP .NET MVC3 Application Structure with Code(Read Data))

The first time I learned Model-View-Controller(MVC) concept, it was very difficult to understand concept of it. However, by doing a real project I could clearly understand MVC concept. Here is an example that read data from database and show result using MVC concept in ASP .NET framework. I hope it is helpful for programmers who want to learn MVC concept.

Web Application MVC Project Structure in ASP .NET

App_Data : Physical data is stored

Content : CSS, images and any other static files are saved

Controllers:

Models: Classes that represent the application model for MVC Web Application are stored

Scripts :

Views :

ASP .NET MVC3 ViewBag

A ViewBag is a dynamic object that can be used to pass data from Controllers to Views as you use ViewData[]. It enables developers can use get/set values and add additional fields without strongly-typed classes. To understand this concepts, let's compare ViewData[] and ViewBag.

- Using ViewData[]

-Controller

public ActionResult Index()
{
List<string> colors = new List<string>();
colors.Add("red");
colors.Add("green");
colors.Add("blue");

ViewData["listColors"] = colors;
ViewData["dateNow"] = DateTime.Now;
ViewData["name"] = "Hajan";
ViewData["age"] = 25;

return View();
}

-Views

<p>
My name is
<b><%: ViewData["name"] %>b>,
<b><%: ViewData["age"] %>b> years old.
<br />
I like the following colors:
p>
<ul id="colors">
<% foreach (var color in ViewData["listColors"] as List<string>){ %>
<li>
<font color="<%: color %>"><%: color %>font>
li>
<% } %>
ul>
<p>
<%: ViewData["dateNow"] %>
p>

- Using ViewBag

-Controller

public ActionResult Index()
{
List<string> colors = new List<string>();
colors.Add("red");
colors.Add("green");
colors.Add("blue");

ViewBag.ListColors = colors; //colors is List
ViewBag.DateNow = DateTime.Now;
ViewBag.Name = "Hajan";
ViewBag.Age = 25;
return View();
}

-Views

<p>
My name is
<b><%: ViewBag.Name %>b>,
<b><%: ViewBag.Age %>b> years old.
<br />
I like the following colors:
p>
<ul id="colors">

<% foreach (var color in ViewBag.ListColors) { %>
<li>
<font color="<%: color %>"><%: color %>font>
li>
<% } %>

ul>
<p>
<%: ViewBag.DateNow %>
p>

Software Requirements Specification Template and Example

Software Requirements express the needs and constraints placed on a software product that contribute to the solution of some real-world problem[ALA 04]. Software requirements that are clearly defined help software engineers to better understand the problems they will work to solve. However, defining software requirements is one of the most difficult tasks in software development. In this article, I will show software requirements specification template and example to understand what is clearly defined software requirements.
