In Asp.net for most of the Controls have OnClick property
will be available in (.net 2.0/VSS 2005) by using the
Onclick property at the ClientSide we can open the Webpage
without going to Sever

OnClick Event: This is a property is available for Dropdown
list ,TextBox,CheckBox,RadioButton,Button,LinkButton etc..)
by using this property when ever the user click the Control
this property will be called.This all operations are done at
the Client Side 
only

<asp:button  id="btn"
onclick="window.open('Default.aspx?bck=1','cal','width=250,height=150,left=225,top=125')"
								text="CLICK"	runat="server" CssClass="href"
"></asp:button>

               (or)
<script  language="javascript">
function fnopenpage()
{
  window.open('Default.aspx?bck=1');
 return true
} 
</script>
<asp:button  id="btn" onclick="return fnopenpage();"
								text="CLICK"	runat="server" CssClass="href"
"></asp:button>


bck=1 after the page is not mandatory its a qury string if
requried we can pass any qurystrings like that....

ASP.NET Support multi language support like VB.NET, C#, C++
ASP.NET have easy development IDE
Website can be created much faster in ASP.NET as compared 
to Java
Debugging is very effort-less,so can fix the bugs quicker

ASP.NET supports multilanguages and User Friendly environment and can support many types of languages having the feature of CLR and MSIL ..

application created using .NET platform works faster as 
it's compiler based unlike JAVA which is interpreter based.

asp.net is allmost designed for developing webbased 
applicatioelonS.it supports code behind technique,automatic 
code generation(means no need to write the code for 
designing and placing the controls in IDE) and it reduce 
the burden on the developer.AND parallel development is 
also possible.(means designing and logic part will be 
placed into different pages.one is ".aspx" page and another 
one is ".aspx.cs")and we may also provide the security for 
the logic part.
and development is very faster compare to java and other 
programming languages.

You have to write a Cross Browser scripting on Page load. 
Also you have to written a W3C standard code to avoid the 
errors.

use intefaces...cool

Use asp.net Literal control.

SOAP
simple object access protocol

That is with state protocol that maintain all the 
information but http is not store any information this is 
stateless protocol

A software framework, in computer programming, is an 
abstraction in which common code providing generic 
functionality can be selectively overridden or specialized 
by user code providing specific functionality. Frameworks 
are a special case of software libraries in that they are 
reusable abstractions of code wrapped in a well-defined 
API, yet they contain some key distinguishing features that 
separate them from normal libraries.

FrameWork has Clr

console.output.writeline  give the farmated out while in   
console.writeline  in string  not farmated

Console.Output.Writeline-> Gives the formatted output 
Console.Writeline->Gives the output in String
