I am trying to implement a webservice and am getting the following 
error...

Compiler Error Message: BC30456: 'ItemIndex' is not a member 
of 'System.Web.UI.Control'.

it is occurring for the following code:

<asp:DataList id="dgrdHistory" CellPadding="6" Gridlines="Both" 
AlternatingItemStyle-BackColor="lightblue" Runat="Server" />
<ItemTemplate>
	<%# Container.ItemIndex %> -
	<asp:HyperLink Text='<%# Container.DataItem %>' NavigateUrl='<%# 
Container.DataItem %>' Runat="Server" />
</ItemTemplate>
</asp:DataList>

I have the following reference at the top of the page...
<%@ Import Namespace="System.Data" %>

Any Ideas? 

Thanks,
Frank
