title: Asp.net-mvc PlaceHolder, how to use it?
body: <p>I have my Master Page with some Html.RenderPartial and a random ContentPlaceHolder inside it, more or less like this:</p>
  
  <pre><code>&lt;body&gt;
  
  &lt;% Html.RenderPartial("Controls/Menu"); %&gt;
  &lt;% Html.RenderPartial("Controls/GenericControl"); %&gt;
  &lt;asp:ContentPlaceHolder ID="MyContent" runat="server" /&gt;
  
  &lt;/body&gt;
  </code></pre>
  
  <p>At the moment in the <em>Menu.ascx</em> file I have a list of buttons. In the <em>GenericControl.ascx</em> file there are some buttons to manage the content.<br>
  And I have as many views as buttons in my Menu and the content is so described:</p>
  
  <pre><code>&lt;asp:Content ID="Content1" ContentPlaceHolderID="MyContent" runat="server"&gt;
  &lt;div&gt;Some divs here&lt;/div&gt;
  &lt;asp:Content&gt;
  </code></pre>
  
  <p>And here's my problem.
  I would like to put another <em>asp:Content</em> in my views, I don't want to link it in the Master Page but in the GenericControl.<br>
  Obviously I can't use the ContentPlaceHolder. I'm trying to use the PlaceHolder instead but I'm having some problems to find how to use it.</p>
