1. Simple But Interesting Features of VS2012: Part 1

This is the continuation of my previous article Simple But Interesting Features of VS 2012: Part 1. Here are more features I have explored.

JavaScript Matching Braces

If we are writing any function in JavaScript which has too many opening and closing braces, and if we miss one of the closing braces, then it becomes very difficult to identify which opening brace is missing a closing brace. With .Net 4.5 we can select a brace and it identifies the closing brace, so it becomes easy to identify the nesting structure. See:



JavaScript Code outlining

Until the previous versions, outline was only supported for .cs and .aspx files, now outlining regions are available in JavaScript too. It helps us to collapse the file or function which is currently not part of our focus. See:



Request Validation

Cross-scripting is a security threat when a developer allows scripts and HTML tags. But in many situations we need our page to support HTML and scripts. In such situations .Net 4.5 provides us with two features:

1. Deferred "lazy" request validation- for selective part
2. Access to unvalidated request data

Whenever a request is made, it's always validated for the complete data and if it is turned off then it is not validated at all. Using Lazy request validation only the required data will be validated. To enable lazy request validation set the "requestValidationMode" attribute to "4.5" in the "httpRuntime" element in web.config.



How this will work is, let's take a simple example; if I wish to validate data when a particular button is clicked, in such a scenario, I don't want that when the page loads, the request should be validated, it should instead be validated whenever the button is clicked. This was not possible with the earlier versions of .Net, but now lazy request validation will do it in .Net 4.5.

It can be used like:
