| Introduction |
JavaScript is one of the very versatile scripting languages
that are used in Web applications. Even though we can accomplish everything in
server side programming using C#, we can still prefer to do some of the things,
like validations, etc., using JavaScript. In ASP.NET 1.x, we do not have that
much support in the framework to hook JavaScript functions from the asp.net
page dynamically. This drawback was addressed with the release of ASP.NET 2.0
by providing developers a lot of features to embed JavaScript blocks
dynamically through a class called ClientScriptManager. I have divided this
article into 2 parts. Part 1 will deal with 3 different methods that are packed
with ClientScriptManager class with examples, while the Part 2 will discuss the
left out methods with some other useful JavaScript tips for ASP.NET.

Hi,
I think this is a good article. RegisterOnSubmitStatement() Method was explained in a simple way. I might have to use this method. However, I have read that in these methods it is more efficient to use typeOf(this) or typeOf(Page) instead of this.getType() or Page.getType()
