How to add item to the beginning of List<T>?

Question

I want to add a "Select One" option to a drop down list bound to a List<T>.

Once I query for the List<T>, how do I add my initial Item, not part of the data source, as the FIRST element in that List<T> ? I have:

// populate ti from data                List<MyTypeItem> ti = MyTypeItem.GetTypeItems();     //create initial entry     MyTypeItem initialItem = new MyTypeItem();     initialItem.TypeItem = "Select One";     initialItem.TypeItemID = 0; ti.Add(initialItem)  <!-- want this at the TOP!     // then      DropDownList1.DataSource = ti; 

Answer 1

Use the Insert method:

ti.Insert(0, initialItem); 

Answer 2

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">     <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem> </asp:DropDownList>
