cascade change other control based on dropdownlist control changes

[Guest]

Hi,

I have a dropdownlist control and a few textbox on my web form. How can I
update those textbox content when user select item from dropdownlist control?
I really want to do this on client side so that don't need back to server.
Thanks.

Hi William
in the property of dropDownList make AutoPostBack=true
and in the events of dropDownList.selectIndexChange write ur code

William,

Basically, you just need to operate on DHTML objects corresponding to your
page elements. A ddl renders as an html <select> element and a textbox
renders as <input type="text">. You need to setup a client site javascript
onchange event handler for the dll that will get the selected text or value
and populate the textboxes.

Use Attributes["onchange"] = "onDllChange()" to setup the event.
