title: BindingSource, set datasource and then set a NEW datasource
body: <p>I've got a BindingSource with only 1 object as the DataSource.</p>
  
  <p>I bind on some values on the datasource. That works perfectly.</p>
  
  <p>BUT.</p>
  
  <p>When I do:</p>
  
  <pre><code>bindingSource.DataSource = new Foo () { Bar = "..."; } 
  </code></pre>
  
  <p>this is not reflected through the UI.</p>
  
  <p>is there a way to force an update?</p>
  
  <p>I tried resetbindings on the controls that bind to the datasource but no luck.</p>
