The ViewBag Property in ASP.NET MVC 3 is Just Syntactic Sugar

2011-11-19T04:00:00.001-08:00

The MVC Controller can pass data to the View using multiple ways. It can either use a strongly typed object or use a global dictionary such as ViewData etc. ASP.NET MVC 3 introduces a dictionary in the Controller base class called the ViewBag property to access view data.

While conducting a Silverlight training at one of my clients who was migrating from ASP.NET AJAX to Silverlight 4.0. While discussing input validations, my students raised a question that in AJAX we have the FilteredTextExtender using which the TextBoxes can be restricted to accept only Character or numeric data.

Conditional CSS and JavaScript for Different Browsers

2011-07-22T21:59:00.000-07:00

A common technique adopted by developers is to detect browsers and conditionally differentiate CSS rules and JavaScript for specific versions of browsers. In simple words, a requirement could be that if the browser is IE, use a different set of CSS and JavaScript files. Let us see how to achieve this using conditional comments. In the example shown above, if the browser is IE, iescript.js is

Create Social Games in Windows Azure

2011-07-21T20:05:00.000-07:00

I recently stumbled upon the Windows Azure Toolkit for Social Games that includes accelerators, libraries, developer tools, and samples that can be used in games created using .NET or HTML5.

Text Shadow Filter in IE

2011-07-20T22:32:00.000-07:00

You can drop shadows to text using the text-shadow property which was re-introduced in CSS3.

JavaScript: Convert CamelCase to Dashes and vice-versa

2011-07-18T23:29:00.000-07:00

My colleague Satyam shared a nice piece of JavaScript code that converts a camelcase to dashes and dashes to Camelcase. For eg: if the string has a camelcase in it - like ‘viceVersa’, the result expected is ‘vice-Versa’. Similarly if a string has a dash in it, like ‘dot-net’, the result expected is ‘dotNet’. Let’s see the piece of code to make this possible: <script type="text/javascript"

Upside Down Text with CSS3

2011-07-14T23:58:00.000-07:00

When it comes to rotating, tilting or scaling text, you would normally rely on JavaScript or images laid on top of each other, to give that effect. However with the CSS3 transformation functions, you can do all of this without any JavaScript code. Although you can use CSS relative/absolute positioning and achieve some of these effects, CSS3 transforms gives you flexibility and more control. For

Unary plus operator in JavaScript

2011-07-13T23:16:00.000-07:00

The unary plus (+) operator is a unary operator and converts its operand to a number, if it isn’t already. It is equivalent to the Number() constructor called as a function. Let us see some examples of the Unary + operator and what does it imply in different scenarios +new Date; // implies Number(new Date)a + “” // implies String(a)+a // implies Number(a), so “+1.2” becomes 1.2a = null; a = +a; /

JavaScript Object can have Private Methods

2011-07-11T20:19:00.000-07:00

I was watching a JavaScript video tutorial by Douglas Crockford where he explained private members in JavaScript. Although there are no ‘private methods’ in a JavaScript object, we can easily create something similar by defining a function variable with a local scope. As crockford says “If a value is a function, we can consider it a method”. Let us see a simple example that shows how to use a

Array Shuffle in JavaScript

2011-07-08T23:01:00.000-07:00

I have yet to find a script that truly does a random shuffle across all browsers using JavaScript (no frameworks). However there are a couple of scripts I use, that are ‘good-enough’ to be used when an Array has to be shuffled. One of them which works well with a large set of records and handles good amount of iterations without hanging the browser is the Microsoft’s Shuffle alogrithm. I learnt

JavaScript: View Source code without Comments

2011-07-07T22:30:00.000-07:00

One my clients had a requirement of viewing an object while debugging, and they wanted to view only the source code, without comments. I first thought of looking out for a similar approach implemented in one of the javascript minifiers. But on further digging, I found that JavaScript has a toSource() method. The drawback is it is gecko-only and works only in Firefox. Since the source code had

ASP.NET 4: Register HTTP Module at Runtime without Editing your Web.config

2011-06-26T23:00:00.000-07:00

The ASP.NET pipeline allows HTTP modules to be plugged-in to a request and intercept or modify each individual request. Modules can be used for processes like caching, authentication etc. However a basic requirement for an HTTP module to function, is that it must be registered in your config file. This leads to editing the Web.Config whenever you have to add/remove modules. I hate fudging with my
