NavigateURl leads to HTTP Error 400 - Bad Request
<p>Ok I have a gallery with thumbnail images that is sorrounded with a tags like this</p>

<pre><code>&lt;asp:Repeater ID="Repeater" runat="server"&gt;
&lt;ItemTemplate&gt;
&lt;asp:HyperLink NavigateUrl= '&lt;% String.Format("?name = {0}", Container.DataItem) %&gt;'
runat="server"&gt;
&lt;asp:Image CssClass="images" ImageUrl= '&lt;%# String.Format("~/pictures/thumbs/{0}",
Container.DataItem) %&gt;' runat="server"&gt;
&lt;/asp:Image&gt;
&lt;/asp:HyperLink&gt;   
&lt;/ItemTemplate&gt;
&lt;/asp:Repeater&gt;
</code></pre>

<p>But when I click an image I just get the HTTP Error 400 - Bad Request error.</p>
