On the aspx:
<table>
<tr>
<asp:Repeater ID="rptHeader" runat="server">
<ItemTemplate>
<th><%#Eval("Category")%></th>
</ItemTemplate>
</asp:Repeater>
</tr>
<tr>
<asp:Repeater ID="rptContents" runat="server">
<ItemTemplate>
<td valign="top">
<%#Eval("Content")%>
</td>
</ItemTemplate>
</asp:Repeater>
</tr>
</table>
On the code-behind:
protected void Page_Load(object sender, EventArgs e)
{
rptHeader.DataSource = DataSource;
rptHeader.DataBind();
rptContentBlocks.DataSource = DataSource;
rptContentBlocks.DataBind();
}
The problem here is that instead of using Two repeaters, can we use only one? We actually need the header to be separated from the contents using a different table row...
Edit: changed rptHeader's ItemTemplate's html element from <td>
to <th>
to be a little clearer. :-)
IMO it's impossible without repeater hacking. Anyway, there is a rather irregular approach that maybe works. Also you can use two foreach statements instead of repeaters.
Code
protected string[] headers = { "A", "B", "C", "D" };
protected string[] contents = { "Alpha", "Beta", "Counter", "Door" };
//string[] headers = { "A", "B", "C", "D" };
//string[] contents = { "Alpha", "Beta", "Counter", "Door" };
//DataList1.RepeatColumns = headers.Length;
//DataList1.DataSource = headers.Concat(contents);
//DataList1.DataBind();
Html markup
<table>
<tr>
<%foreach (string item in headers)
{ %>
<th><%= item %></th>
<% } %>
</tr>
<tr>
<%foreach (string item in contents)
{ %>
<td><%= item %></td>
<% } %>
</tr>
</table>
<!--
<asp:DataList ID="DataList1" runat="server" RepeatDirection="Horizontal">
<ItemTemplate>
<%# Container.DataItem %>
</ItemTemplate>
</asp:DataList>
-->
