ASP .NET - RequiredFieldValidator creates space after textbox
<p>I have a DetailsView with a number of textboxes setup with RequiredFieldValidators.</p>

<p>The code for both is:</p>

<pre><code>&lt;InsertItemTemplate&gt;
   &lt;asp:TextBox ID="TextBox1" runat="server" Text='&lt;%# Bind("date_time") %&gt;'&gt;&lt;/asp:TextBox&gt;
   &lt;asp:RequiredFieldValidator 
         ID="RequiredFieldValidator11" 
         runat="server" 
         ControlToValidate="TextBox1"
         ErrorMessage="Please update date_time." 
         ValidationGroup="InsertDetailsView1"&gt;*&lt;/asp:RequiredFieldValidator&gt;
  &lt;/InsertItemTemplate&gt;
</code></pre>

<p>The problem is that the validation control is now creating a space (ie <br>) between the textbox and the one below it.  How do I get rid of the space?  Is it a CSS thing?</p>
