Autoscrolling a datalist in an ASP page

Autoscrolling a datalist in an ASP page

I have an Aspx page with a panel and a datalist inside it connected to a
datasource. The datalist is showing news from an RSS feed and I have set
scroll bars to allow the users to read the hidden once. This is my code:
<asp:Panel ID="Panel1" runat="server" Height="270px" ScrollBars="Vertical"
Width="790px" BorderStyle="Outset" Direction="LeftToRight">
<asp:DataList ID="DataList3" runat="server" style="text-align:
left" DataSourceID="XmlDataSource1" CellPadding="4"
Font-Bold="False" Font-Italic="False" Font-Overline="False"
Font-Strikeout="False" Font-Underline="False"
ForeColor="#333333" HorizontalAlign="Justify">
<AlternatingItemStyle BackColor="White"
ForeColor="#284775" HorizontalAlign="Justify" />
<EditItemStyle Height="300px" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True"
ForeColor="White" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True"
ForeColor="White" />
<ItemStyle BackColor="#F7F6F3" ForeColor="#333333" />
<ItemTemplate>
<%#XPath("title")%>
<br />
<%#XPath("pubDate")%>
<br />
<%#XPath("author")%>
<br />
<%#XPath("description")%>
</ItemTemplate>
<SelectedItemStyle BackColor="#E2DED6" Font-Bold="True"
ForeColor="#333333" />
</asp:DataList>
</asp:Panel>
I am trying to make the news scrolling continuously and if the user goes
over the control with the mouse, stop the autoscrolling and give control
to the mouse. How can I do something like that? Any reference or hint will
be appreciated.
