In VB6 it was really easy to load a ComboBox with data and then
use the ItemData property to associate a key value or something with the
item in the list.

There looks to no longer be an ItemData property... So,
how do you load manually (for example) Customer Names and Customer ID's into
a ComboBox -- showing the Customer Names but when one is selected, use the
Customer ID? Again, I want to do this manually and not use DataBinding.

Here are two ways: In your .aspx (or .ascx) do the following:

<asp:ListBox id=3D"foobar" runat=3Dserver>
<asp:listitem value=3D"1" Text=3D"Item 1" />
<asp:listitem value=3D"2" Text=3D"Item 2" />
<asp:listitem value=3D"3" Text=3D"Item 3" />
<asp:listitem value=3D"4" Text=3D"Item 4" />
</asp:ListBox>

<select id=3D"foobar" runat=3Dserver>
<option value=3D"1">Item 1</option>
<option value=3D"2">Item 2</option>
<option value=3D"3">Item 3</option>
<option value=3D"4">Item 4</option>
</select>

if you are talking winforms, then you need to ask on one of the winforms =
lists:

Even though you said vb in the past, I'm assuming you mean C# since you =
sent the email to a C# list. However, if you ment vb.net then try:
http://www.aspfriends.com/aspfriends/winforms-vb.asp
for winforms

You can also set this when you bind data to your listbox:

//foobar listbox

//Get some datatable/reader/dataset (mydata)with two columns: CustomerID, CustomerName

//Then:
foobar.DataSource = mydata;
foobar.DataValueField = "CustomerID";
foobar.DataTextField = "CustomerName";
foobar.DataBind();

No when you access the information on postback:
foobar.SelectedItem.Value will give you the selected CustomerID
foobar.SelectedItem.Text will give you the selected CustomerName

HTH,
Scott
