FormView DropdownList - On Selection Change populate Text Box

C#, ASP.NET
Q: Have a formview, with a dropdownlist which is bound to a column. This
dropdownlist has a datasource of DataSet type. Now my objective is, on
Selection Changed of this DropdownList, I need to populate a couple of
TextBox's. How can I do this? What event does the code go into? The
selectionindexchanged even for the DropDownList does not seem to fire.

Any help is appreciated.

Thanks in advance.

The selectIndexChanged event absolutely should fire. However, if you are
expecting it to cause a postback when you change the selection, you need to
set the AutoPostback property= true in the properties for this control.

Once you have got the event fireing its jsut a matter of writing your code
based on the selected index data.

Nope, tried adding code in SelectionIndexChanged Event and even tried with
the Debugger, nothing.

Does your page_load event fire ?, if not, check that your Autowireup event
is set to true. Also, you didnt comment on the Autopostback I mentioned have
you checked this.

Whatever you problem is, its likely to be very basic.

Page load fires, regardless of Postback - true/false.

However, the selectionindexchanged event just does not fire.
I read thru the AutoEventWireup attribute and made sure that it is set to
true everywhere, webconfig as well as the aspx page itself.

I am also using VS2008.
