Populate .net dropdown

I have 2 tables. One is country and holds a list of countries and the other
is region which holds a list of states/provinces/countys relating to that
country.

How do I populate a combo so that it is indented.

e.g

USA
-Florida
-California
-Utah
Canada
-Ontario
-Quebec
England
-Kent
-Northumberland

TIAYou get real familiar with the dropdownlist.add() method, because this isn't
something you are going to acheive with the standard way of doing things.
First you have to design a query to return
countries/states/provinces/countys sorted by country, then you have to loop
through them, set some variable to the current country, and then pop either
a Country, or a state/province/county in the dropdownlist using the .add
method. If it is a state/province/county you'll probably need to add
something to the beginning to actually indent it. Then you'll have the
problem of finding out if they selected a country or a
state/province/county.

sounds fun!

populating a dropdown list from arraylist of objects

hi there,
i have an arraylist which holds my Customer object, that contains the
customer details, but when i try binding it to a dropdown box, i cant get
the values to appear..
this is what i tried:
customerList.DataSource = Customer.GetAdminList()
customerList.DataBind()
customerList.DataTextField = CType(customerList.DataSource,
Customer).Email.ToString
customerList.DataValueField = CType(customerList.DataSource,
Customer).CustomerID.ToString
customerList.Items.Insert(0, "--ALL CUSTOMERS--")
this error returns me a invalid cast error..so i also tried the normal
method:
customerList.DataSource = DotcoCustomer.GetAdminList()
customerList.DataBind()
customerList.DataTextField = "email"
customerList.DataValueField = "customerID"
customerList.Items.Insert(0, "--ALL CUSTOMERS--")
but this populates the dropdown list with the the values
"Web2004.Customer" - which is my application namespace.Object...'
any help appreciated,
Paul.Rearrange the order of your code:
customerList.DataSource = DotcoCustomer.GetAdminList()
customerList.DataTextField = "email"
customerList.DataValueField = "customerID"
customerList.DataBind()
customerList.Items.Insert(0, "--ALL CUSTOMERS--")

populating asp:dropdownlist programmatically

I need to display a drop down list which holds up to 250 listitems.

I'd like to create this programmatically rather than have to hardcode it
into the page.

For example

<asp:DropDownList id="numYears" runat="server" name="numYears">
<asp:ListItem Value="0" Text="0 years" Selected="true" />
<asp:ListItem Value="1" Text="1 year"/>
<asp:ListItem Value="2" Text="2 year"/>
<asp:ListItem Value="2" Text="2 year"/>
<asp:ListItem Value="3" Text etc.......... up to 250 years

Thanks in advance..

Simon AmesHi,

put the DDL declaration at the Page (or create it in code just as you see
better).

<asp:DropDownList ID="ddl1" Runat="server">
</asp:DropDownList
Then say in Page_Load:

= = =
if(!Page.IsPostBack)
{
for(int i=0;i<251;i++)
{
ListItem litem=new ListItem(i.ToString() + " years",i.ToString());
ddl1.Items.Add(litem);
}
ddl1.SelectedIndex =0;
}
= = =

for (int i=0; i<=250; i++)

{

numYears.Items.Add(i.ToString());

}
