How to copy items from one DropDownList to another

Question

How can I copy items hardcoded from one dropdown box to another keeping the keys and values?

drpTypes.Items.Add(new ListItem("Tipos de Acções", "1"));
drpTypes.Items.Add(new ListItem("Tipos de Combustível", "2"));
drpTypes.Items.Add(new ListItem("Tipos de Condutor", "3"));

drpTypesCreateEdit.Items.AddRange(drpTypes.Items);

Answer 1

AddRange wants an array of ListItems. you can do it like this (C# 3+).

drpTypesCreateEdit.Items.AddRange(drpTypes.Items.OfType<ListItem>().ToArray()); 

Answer 2

This would be one of the easier ways..

drpTypes.Items.Add(new ListItem("Tipos de Acções", "1"));
drpTypes.Items.Add(new ListItem("Tipos de Combustível", "2"));
drpTypes.Items.Add(new ListItem("Tipos de Condutor", "3"));

foreach(ListItem li in drpTypes.Items)
{
    drpTypesCreateEdit.Items.Add(li);
}

Do you need something more elaborate?
