Create table from a business object with conditional layout - asp.net

Question

I need to generate a table from a List (Of Students). My Student class has properties for AcademicYear, TeachingSet, Surname and Forenames, is sorted in that order and also properties for ID and start date. The table should nest TeachingSets within AcademicYears and then the students within the TeachingSets, as shown in the table I've mocked up at http://www.ifslearning.ac.uk/files/student-table.jpg
Using a repeater I get
08-10 students B74394 Mzejb Bsppn
08-10 students B74395 Lbuifsjof Bvti
08-10 students C68924 Epoob Cmpblf
08-10 students D41468 Ipxbse Dbwfz
But I need to have
08-10 students
- B74394 Mzejb Bsppn
- B74395 Lbuifsjof Bvti
- C68924 Epoob Cmpblf
- D41468 Ipxbse Dbwfz

If you use asp .net Web Forms then you can look at ListView, DataList and Repeater controls. I would recommend you to try ListView. Here is a deep description about using this control. It is very simple to configure any layout you need:
<asp:ListView runat="server" ID="ListView1">
<LayoutTemplate>
<table>
<tr runat="server" ID="itemPlaceholder" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td><%#Eval("YourObjectProp") %></td>
...
</td>
</ItemTemplate>
</asp:ListView>
You can group your objects like this:
List<AcademicYear> academicYears = new List<AcademicYear>();
var year = new AcademicYear { Year = "08-10" };
year.Students.Add(new Student { Name = "Mzejb Bsppn" });
year.Students.Add(new Student { Name = "Lbuifsjof Bvti" });
...
And layout:
<asp:ListView runat="server" ID="ListView1">
<LayoutTemplate>
<asp:PlaceHolder runat="server" ID="itemPlaceholder" />
</LayoutTemplate>
<ItemTemplate>
<%#Eval("Year") %> students<br />
<asp:ListView runat="server" ID="nestedListView" DataSource='<%# Eval("Students") %>'>
<LayoutTemplate>
<asp:PlaceHolder runat="server" ID="itemPlaceholder" />
</LayoutTemplate>
<ItemTemplate>
<%#Eval("Name") %><br />
</ItemTemplate>
</asp:ListView>
</ItemTemplate>
</asp:ListView>
