PostBack without page refreshing

Hi, guys!

I have a very important question for me.

Does anyone know how to PostBack without page refreshing?

The situation is as following:

There are 2 DropDownLists on my page,

when I select any item from DropDownList1,

DropDownList2 must fill with items from SQLServer without any refreshing of page,

as if it works on desktop application.

Is it possible?

Thanks!

Hi,

check out theCascadingDropDown in the Toolkit.

Grz, Kris.

Hi,

you can put each of ddl into one UpdatePanel with AutoPostBack="true", then you have the postback of only the part of the page included in UpdatePanel.

Bye!
