VS 2010 Code Being Auto Formatted Wrong Way

I've had this problem for a while now, it seems to come and go (sometimes it happens, sometimes it doesn't) and I can't really figure out what's wrong.Basically my aspx code will sometimes format automatically, except not in the way I want it to. I always structure html and xml-like code as such:

Code:
<parent>
<child />
<child>
<subchild />
<subchild />
</child>
</parent>

This way I can quickly see which tags belong to which, and I think this is the usual way html is formatted, right? Anyway, suppose that I have this code in my aspx code window (don't mind that it's not aspx code, that's not the point), then sometimes VS will automatically format it to this:

Code:
<parent>
<child />
<child>
<subchild />
<subchild /></child></parent>

Basically it seems to put all closing tags on the last line, leaving me sometimes (with many nested tags) with an extremely long line at the end, making it completely impossible to see the structure of my code. Here is an actual example. This is how I wrote my code:

xml Code:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Login</h2>
<p>
<asp:Label runat="server" ID="lblMessage" Font-Bold="true" ForeColor="Red" />
</p>
<p>
<asp:Table runat="server">
<asp:TableRow>
<asp:TableCell>Gebruikersnaam:</asp:TableCell>
<asp:TableCell Width="35px" />
<asp:TableCell>
<asp:TextBox runat="server" ID="txtUsername" />
