You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. You create a Web page that contains the following two XML fragments：  
01 <script runat="server">  
02 ► 
03 </script>  
04 <asp：ListView ID="ListView1" runat="server"

11       Text=’<%# Eval（"LineTotal"） %>’ />  
12   </td>  
13 </ItemTemplate>   
The SqlDataSource1 object retrieves the data from a Microsoft SQL Server 2005 database table. The database table has a column named LineTotal. 
You need to ensure that when the size of the LineTotal column value is greater than seven characters， the column is displayed in red color.
