Set display order of ListBox control

[Hardy Wang]

Hi
I have a ListBox control in my ASP.NET page. After I binding data to this
control, I would like to be able to change this display order of items in
this control. Just like change layout function of my.yahoo.com.
I tried client side approach, yes I can change display order by JavaScript,
but after clicking one of the button the display order will reverse back to
its original status. Because after PostBack, the page will try to render
this control by viewstate again.

I tried server side approach, but looks there is no way to switch two
ListItems programmaticall y.


Is there anybody who has some good idea?

Thanks!

Re: Set display order of ListBox control

Dump content of listbox to array, sort array in memory, then clear this
listbox and add listitem from array one by one.

Re: Set display order of ListBox control

Yep.
That is what my listbox sort routine does.
Just wondering if you came up with something different.
