How to create a simple model in ASP.NET MVC and display the same?(PART-4)

Step1:- Create a simple class file

The first step is to create a simple customer model which is nothing but a class with 3 properties code, name and amount. Create a simple ASP.NET MVC project, right click on the model folder and click on add new item as shown in the below figure.

KEYWORDS,IDENTIFIERS and DATA TYPES in C#.Net

Introduction

KEYWORDS :
Keywords are the words which are language specific. A keyword is an essential part of a language definition. These words cannot be used as identifiers. Identifiers are nothing but names given to various entities used in a program. The examples of keywords are event, byte, break, using, class..etc

IDENTIFIERS :
Identifiers are program-defined tokens. Identifiers are names of various program elements like classes, methods, variables, namespaces, interfaces...etc. in the code that uniquely identify an element. Now let us see what these entities are.

IList Generic Interface

IList Generic Interface represents a collection of objects that can be individually accessed by index.

This example demonstrates how to use IList Generic Interface to store data.
IList Generic Interface represents a collection of objects that can be individually accessed by index.
First, you will need to import the System.Collections.Generic namespace.
using System.Collections.Generic;

MenuStrip in C#

The MenuStrip class is the foundation of menus functionality in Windows Forms. If you have worked with menus in .NET 1.0 and 2.0, you must be familiar with the MainMenu control. In .NET 3.5 and 4.0, the MainMenu control is replaced with the MenuStrip control.

Creating a MenuStrip

We can create a MenuStrip control using a Forms designer at design-time or using the MenuStrip class in code at run-time or dynamically.

To create a MenuStrip control at design-time, you simply drag and drop a MenuStrip control from Toolbox to a Form in Visual Studio. After you drag and drop a MenuStrip on a Form, the MenuStrip1 is added to the Form and looks like Figure 1. Once a MenuStrip is on the Form, you can add menu items and set its properties and events.

Dynamically populate drop-down that is part of form array

I will show you the HTML code, this code consist of two dropdownlist / combo box (two <select> element) with the second <select> element disabled and will be enabled if we choose something from the first <select> element. Here the HTML code (dnmddl.htm):

Using Settings in C#

Introduction

The .NET Framework 2.0 allows you to create and access values that are persisted between application execution sessions. These values are called settings. Settings can represent user preferences, or valuable information the application needs to use. For example, you might create a series of settings that store user preferences for the color scheme of an application. Or you might store the connection string that specifies a database that your application uses. Settings allow you to both persist information that is critical to the application outside of the code, and to create profiles that store the preferences of individual users.

While Visual Basic 2005 has provided an easily discoverable mechanism for accessing settings using the My namespace, there is no analogous namespace in Visual C# 2005, and thus settings are somewhat more difficult to access. Nonetheless, C# users can still use settings by accessing the Properties namespace. In the course of this article, you will learn the difference between application and user settings, how to create new settings at design time, how to access settings at run time, and even how to incorporate multiple sets of settings into your application.
