title: Get Dependecy Property from Binding expression
body: <p>I have a Binding expression object:</p>
  
  <pre><code>//e come from Validation.Error event
  BindingExpression _bindingExpression = e.Error.BindingInError as BindingExpression;
  </code></pre>
  
  <p>I want to get the Dependecy Property. </p>
  
  <p>For example, if the <code>bindingExpression</code> is a text of TextBox I want to get <code>TextBox.TextProperty</code>, etc..</p>
  
  <p>Is this possible?</p>
