In this article we will understand if we don't want to update certain fields means Uninted Updates how we acheive that in Asp.Net MVC By Sagar Jaybhay. Uninted Updates In the previous article, we know how to Edit the details but here as you see all fields are editable and you will able to change that all. but we don’t want to change that ID and Name field and want to mark this as read-only to do this we change the Html helper method from EditFor to DisplayFor.

In this article we will understand In Depth about Cookies in JavaScript . By reading this article you will able to create Cookies, Delete Cookie By Sagar Jaybhay . If you see web application works on HTTP protocol and the HTTP protocol is a stateless protocol. The meaning of this is when we request some data, web page after filling some information on the webpage the webserver does not remember anything about that request after processing that request but we want our web application to remember users choice. This means if I fill my first name on the page after the subsequent request the page should know what information I filled in that textbox but the page doesn’t remember that so why this happens because web pages use the HTTP protocol to serve the webpage and HTTP is stateless. Meaning that after processing the request of client web server doesn’t remember about the client settings to remember this we have several options but one of the easiest and common way is use cookies. functio

In this article we will learn How to generate HyperLink In MVC(Asp.Net MVC) by Sagar Jaybhay . For this, we need to use Html.ActionLink helper function is used to generate an action link.

In this article we will under stand How to Pass Data From Controller to View by Sagar Jaybhay . How to Pass Data From Controller to View using ViewBag and ViewData? ViewBag and ViewData In Asp.Net MVC Both are used to pass data from controller to view. ViewData is a dictionary of objects which store and retrieve the data based on key. ViewData["Today"] = DateTime.Now; See the above code. https://www.youtube.com/watch?v=7mZ89MvGnzU ViewBag uses the dynamic keyword internally and the dynamic keyword is introduced in C# v4. It allows objects to add as properties. ViewBag.list = list; See the above code. In this, both do not provide compile-time error checking. Means if given ABC as a key name in the controller and in view if you misspell Abc then it will not provide compile-time checking. You will get the error at runtime only. It is good practice to pass data from controller to view using a strongly typed model. ViewBag is a sugar coating over ViewData. Internally ViewB

How to implement Abstract Classes & Object reflection & Strict Mode In JavaScript ?

Abstract Classes Object-oriented programming languages like C# and java support abstract classes. These classes are incomplete and when you trying to create an object of that abstract classes it will throw a compile-time error. The abstract classes are mainly for base classes. var Shape=function(nameofshape) this.shapeName=nameofshape; throw new Error("You can't create object of this abstract class.") ; Shape.prototype.draw=function() return "Drawing the Shape "+this.shapeName; var Circle=function(name) this.shapeName=name; Circle.prototype=Object.create(Shape.prototype); var circle=new Circle("Circle"); document.writeln("<br/>"); document.writeln("is circle instance of Circle "+(circl
