Ajax Error in Visual Studio 2008

Sometimes if we try to deploy an existing .NET ASP.NET 2.0 application which includes Ajax 1.0 library using Visual Studio 2005 we get following error


Could not load file or assembly ‘System.Web.Extensions, Version=3.5.0.0, ….


If you are using Ajax Famework Library, Visual Studio 2005 and Visual Studio 2008 installed in the same machine there are somethings you should be aware of.


Microsoft suggests that after the VS 2008 Beta 2 installation has finished, you should run this script to ensure that the installation of .NET Framework 3.5 Beta 2 will not affect the development of ASP.NET AJAX 1.0 applications.


If you want to target the AJAX 1.0 in Visual Studio 2008, check out this post Targeting AJAX 1.0 in VS 2008

Disable right mouse click, Disable Browser Back Button

Sometime our application demands to change some of the normal workflow of the Browsers. Here are the few tweaks in programming which may help you to do that.

Do not allow user to view page using browser back button.

<%Response.Cache.SetCacheability(HttpCacheability.NoCache); %>

Disable Right Click

This is a cross browser DHTML script that will prevent the default right menu from popping up when the right mouse is clicked on the web page. Use it to stop surfers from easily saving your web page, viewing its source, or lifting images off your site when using either IE 4+ or NS 4+.

<script language=JavaScript>
<!--

var message="Function Disabled!";

///////////////////////////////////
function clickIE4(){
if (event.button==2){
alert(message);
return false;
}
}

function clickNS4(e){
if (document.layersdocument.getElementById&&!document.all){
if (e.which==2e.which==3){
alert(message);
return false;
}
}
}

if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}

document.oncontextmenu=new Function("alert(message);return false")
