about javascript
in page 354, i write var YourName = $get('YourName'). value but intellisense doesn't recognize the value , it doesn't mention it in the list, also in the same source page, its gives me a warning the page cannot find the aspx.cs file??
another question about this javascript the helloworldcallback parameter result.. this is a constant name in all methods ? like the error parameter?
just these 3 questions :D
and why should the javascript code be below the button and textfield? can't it be above?

That's by design. You can manually enter the value property.

Hard to tell what the problem is as you're not giving me enough information as to where and how you get this error, what page this is about, whether or not the file is there and so on.

I don't understand this question.

the 3rd question, is the parameter always called result, and error? or could they be named other names?
another thing, does the javascript code has to be below the button and text?

The best answer I can give you to that question (as you'll learn the most from it - which is what programming is all about) is: why don't you try it out?

The functions can be placed anywhere, but the handler code has to be below as it requires the controls to be present in the HTML. If you don't want that, you can use code like jQuery's document ready to postpone exeution until the DOM has finished loading (which means the referenced controls are available).
Cheers,
Imar
