dropDownList always returns 0 for selected index

[Dica]

if i manually populate a dropDownList, post the page, and then fetch the
selected index, i'm able to get values other than 0. however, when i bound
my dropDownList to a dataReader object, even thought he dropDown's text and
values are showing the dataReader's data fine, i can never return a
selectedIndex other than 0.

lstCompanies.DataSource = oDataReader

lstCompanies.DataTextField = "companyName"

lstCompanies.DataValueField = "id"

lstCompanies.DataBind()

any ideas why?

tks

Where has this code been placed - in the Page_Load event? And is it
inside a IsPostBack check.

If Not Page.IsPostBack Then
'databinding goes here
End If

have you forgotten the IsPostBack check ?

the code should look like

if(!Page.IsPostBack())
{
// code to databind lstCompanies...
}

yes, you're both right. adding a isPostBack() fixed everyting.
