Horizontally tile tables in listview? - asp.net

Question

I have records from database separated by department, I want to tile them horizontally inside different tables (for each department). Here is what I tried (This does not work)
Aspx
<asp:ListView ID="lvUnderwriting" GroupItemCount="6" runat="server" GroupPlaceholderID="grpPlaceHolder1" ItemPlaceholderID="itemPlaceHolder1">
<LayoutTemplate>
<table>
<asp:PlaceHolder ID="grpPlaceHolder1" runat="server" ></asp:PlaceHolder>
</table>
</LayoutTemplate>
<GroupTemplate>
<span><b><%# Eval("gensubbusiclass") %></b></span>
<table>
<tr>
<th>Role Name:</th>
<th>Pending Tasks:</th>
<th>On Leave:</th>
</tr>
<tr>
<asp:PlaceHolder ID="itemPlaceHolder1" runat="server"></asp:PlaceHolder>
</tr>
</table>
</GroupTemplate>
<ItemTemplate>
<tr>
<td><span> <%#Eval("RoleName") %></span></td>
<td><span><%# Eval("Count") %></span></td>
<td><span><%# Eval("OnLeave") %></span></td>
</tr>
</ItemTemplate>
</asp:ListView>
Database rows
My current results. For some reason the second department is divided into two tables. Also how do I tile them horizontally?

Answer 1

Okay what I got was that ListView cannot display master detail records out of the box. Here is what I tried to get it working for me. The trick was to dynamically add a new row to the table if the header databound item was changed, the database records need to be sorted in advance to get this working.

Aspx
<asp:ListView ID="lvUnderwriting" runat="server" ItemPlaceholderID="itemPlaceHolder1">
<LayoutTemplate>
<table border="1" cellpadding="4px">
<tr>
<th>Role Name:</th>
<th>Assigned:</th>
<th>On Leave:</th>
</tr>
<tr>
<asp:PlaceHolder ID="itemPlaceHolder1" runat="server" />
</tr>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<%# AddGroupUnderwriting() %>
<td><%# Eval("RoleName") %></td>
<td><%# Eval("Count") %></td>
<td><%# Eval("OnLeave") %></td>
</tr>
</ItemTemplate>
</asp:ListView>
C#
// Add group row to underwriting grid
private string prevUWBusinessClass = "";
public string AddGroupUnderwriting()
{
string currentUWBusinessClass = Eval("gensubbusiclass").ToString();
if (currentUWBusinessClass != prevUWBusinessClass)
{
prevUWBusinessClass = currentUWBusinessClass;
return string.Format(#"<tr><td colspan=""3""><h3>Department: {0}</h3></td></tr>", currentUWBusinessClass);
}
else
return "";
}
