ASP.NET & C# - Two values in a listbox?
<p>I'm adding ListItems to a ListBox from two controls, both are DropDownLists.</p>

<p>The ListItem has the properties ListItem.SelectedItem and ListItem.SelectedValue, but I also want the ListBox to keep track of which DropDownList the ListItem came from.</p>

<p>What would be the best way to do this?</p>
