I found this article on how to manipulate the rendering sequence of asp.net controls.: http://weblogs.asp.net/infinitiesloop/archive/2007/09/07/rendering-asp-net-controls-out-of-order.aspx
I placed some placeholders on the page to encapsulate the controls i want to move around. The problem is, that RenderChildren does render the controls without the html i placed into the placeholder like this:

<asp:PlaceHolder id="phOneToMove" Runat="server" Visible="true">
<tr>
<td><asp:Literal id="label1" Runat="server">Caption</asp:Literal></td>
<td>
<asp:TextBox ID="textbox1" runat="server"></asp:TextBox>
</td>
<td>
<asp:RequiredFieldValidator ID="validator1" Enabled="true" ControlToValidate="textbox1" runat="server" EnableClientScript="False" ErrorMessage="error"></asp:RequiredFieldValidator>
</td>
</tr>
</asp:PlaceHolder>

The controls are rendered without the tr and td around.
How can I handle this? All I want is to change the order of the placeholders like in this example phOneToMove.

Note: I am running on asp.net 2.0.

    I found the solution. My problem was, that the literal html elements (not LiteralControls) were not in the Controls property of my usercontrol. I did not know why. So I started to debug the .net Framework code itself ans setup a project with no overhead.

    Short: I had code in the ascx file itself like <b><%= myOutputVariable %></b>. This causes asp to not put the literal content of a file into the controls collection. After I removed this code it worked like expected.
