Hi All,

I have 2 list boxes .. and a buttons to move items between them ...

The problem is thta every time I click a button to move items the whole page refreshes ... I understand this is because the buttons are server components so it needs to post to the server ..

HOWEVER ....

Is there a way to get data moving between the boxes without refreshing the page ...

I thought I'd ask ...

If your wanting to populate a listbox from another and visa vers and using a button to transfer the text etc, then you shouldn't need to refresh the page.  It depends what your doing after that.

Are you saving anything to a database after you have changed the lists?

Well the thing is that whenever I push the button (it's an SP button) ... it refreshes the page ...
Probably since all LBs and the Button are all runat="server"

I've had a look at a few sites and a few of my programs and i have no idea if its possible, all my webapps refresh the page when i click a button too.

However, i just put a:
if(!IsPostBack)
{
}

around everything in the Page_Load.  Then my code on page load don't run again.

Hope this helps.
