+Summary: [REGRESSION] ListControl's ViewState handling broken
+
+Commit 81396 broken the ViewState handling of
+ListControl/ListItemCollection. An System.ArgumentOutOfRangeException is
+thrown after the (second?) postback of page containing a dynamically
+populated DropDownList:
+
+<%@ Page Language="C#"%>
+<script runat="server">
+void Page_Load(object o, EventArgs e) {
+	if(!IsPostBack)
+		quantity.Items.Add(new ListItem("0", "0"));
+}
+</script>
+<html>
+<body>
+<form runat='server'>
+	<asp:DropDownList id='quantity' runat='server'>
+		<asp:ListItem text="123" />
+	</asp:DropDownList>
+	<asp:Button text="Postback" runat="server" />
+</form>
+</body>
+</html>
+
+Request the page, click the button (once or twice).
+Result:
+
+System.ArgumentOutOfRangeException: Index is less than 0 or more than or
+equal to the list count.
+Parameter name: index
+0

+
+Reverting to a revision prior to r81396 fixes the problem (e.g.
+"svn up -r {2007-07-04}
+mcs/class/System.Web/System.Web.UI.WebControls/List*.cs").
