What is the use of documented protected properties is in framework classes?
<p>DataGridViewRowCollection has the following properties:</p>

<pre><code>Count (public)
Gets the number of rows in the collection.

DataGridView (protected)
Gets the DataGridView that owns the collection.

Item (public)
Gets the DataGridViewRow at the specified index.

List (protected)
Gets an array of DataGridViewRow objects.
</code></pre>

<p>The question pops to my mind: how would I use these protected members?  I'm assuming they are taking up space in the documentation for a reason.</p>

<p>The scenario I can think of that I suppose could have use is deriving my own class and telling a DataGridView to use that class instead.</p>

<p>However, I don't know how to do that (maybe it's obvious and I just don't see it - that would be the answer here).</p>
