Custom WebControls with Collection property


I've been working on a custom WebControl. I want it to have a property "Items" that contains a collection of custom objects and I want the control to behave within the VS IDE like a Listbox WebControl, generating the following "HTML" tags
<asp:ListBox id="ListBox1" runat="server">
    <asp:ListItem Value="1">First</asp:ListItem>
    <asp:ListItem Value="2">Second</asp:ListItem>

My code looks like this
<cc1:MyControl id="MyControl1" runat="server">
    <cc1:CustomItem prop1="1" prop2="aa"></cc1:CustomItem>
    <cc1:CustomItem prop1="2" prop2="bb"></cc1:CustomItem>

I have everything working except for one little detail:
If I change the items in the collection using the property collection editor the updated items are not generated back into the aspx file. Instead I get this:

<cc1:MyControl id="MyControl1" runat="server" Items="(Collection)"></cc1:MyControl>

Can anyone tell me what attribute, property or override I should use to let the control generate the child tags instead of the Items="(Collection)" attribute?

OK, I got it

public MyCollection Items
    get { return _items; }
