title: Cannot visually change DataGridView in inherited form
body: <p>I have a WinForms form with a <code>DataGridView</code> on it. The <code>DataGridView</code> is set to <code>protected</code>. </p>
  
  <p>When I inherit that form, it is not possible to change the <code>DataGridView</code> in the Visual Studio designer. If I do the whole thing with a <code>Button</code>, it works as expected.</p>
  
  <p>Is there a way to fix this?</p>
  
  <p>Some (clipped) code (from DatagridForm.Designer.cs):</p>
  
  <pre><code>partial class DatagridForm {
      protected DataGridView dgData;
      protected Button button;
  }
  </code></pre>
  
  <p>and from Inherited.cs:</p>
  
  <pre><code>partial class Inherited : DatagridForm {
  
  }
  </code></pre>
