title: like operator in entitydatasource
body: <p>I'm using an EntityDataSource in an asp .net form and a Gridview is bound to it.  A where clause is used in the entityDataSource:</p>
  
  <pre><code>Where="it.Name like '%@Name%'
  </code></pre>
  
  <p><code>@Name</code> is a parameter:</p>
  
  <pre><code>&lt;WhereParameters&gt;
  &lt;asp:ControlParameter ControlID="TextBox1" Name="Name" PropertyName="Text" Type="String"  /&gt;
  &lt;/WhereParameters&gt;
  </code></pre>
  
  <p>But it doesn't work.  When I change <code>@Name</code> with a fixed string it works properly, like this:</p>
  
  <pre><code>Where="it.Name like '%ppp%'"
  </code></pre>
