Hi Vijay..

In the code behind,Wen v trying to access the listbox item countin the target source.. it still showing zero..?? Do u hav any idea abt this issue..??

Really nice code...

Vijay, Nice column, I liked it.

To add to the list, I think in today's time a growing programmer must learn to read books on technology(s) he/she is interested in. Many programmers limit themselves to start with "Hello World" kind of thing and then they carry on the work as it comes with the guidence from web.

I particulary liked one of your statement -"I have seen good programmers who are good in trouble-shooting but poor in design. I have seen some good designers who are weak in trouble-shooting." I believe reading the subject helps in becoming good at designing and after you are exposed to the subject. It's the intution/gut feeling which makes you a good troubleshooter.

Vijay, Nice one :)

I love this line "Is it not common to find managers who appreciate well written emails, polished and respectful conversation more than well-written code?"

Keep writing!

Your code is good.. I love it. Anyway can you help me with this. Can we sort the listbox after moving it..

I want to get the same functionality with php and jquery, any tip, thanks, phycomp01@gmail.com

Correct syntax is:

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(abortPostbacks);

function abortPostbacks(sender, args) {
   if (prm.get_isInAsyncPostBack())
       args.set_cancel(true);
}

Where do you need to add this piece of code? thanks.

From beginning to end you nailed this post to the wall! Great Job!

Hey Vijay,
Your post was really helpful. Thanks for sharing!
