I am able to show a horizontal scroll bar at the bottom of the ListView, however I can figure out how to set it up at the top.
Here is my code:
<div style =" overflow :auto ;width:auto; height:auto">
//omitted
<asp:ListView ID="ListView1" runat="server" OnSelectedIndexChanged="ListView1_SelectedIndexChanged" InsertItemPosition="LastItem" OnPagePropertiesChanged="ListView1_PagePropertiesChanged">
//omitted
</asp:ListView>
</div>
