title: Is there a way to make a two-way MultiBinding only use a converter in a single direction?
body: <p>I have created a custom MultiValue Converter to perform a bit of logic while MultiBinding to a TextBox; however I do not want to use the convertBack since the binding value does not have a compile-time type and the default conversion works perfectly. Is this possible or do I have to somehow replicate the functionailty of one of the internal default converters?</p>
  
  <p>Diagram:</p>
  
  <pre><code>values --&gt; Convert() --&gt; TextBox
  values &lt;---------------- TextBox
  </code></pre>
  
  <p>Thank you.</p>
  
  <p>Edit: Forgot to mention that I am using a MultiValueConverter and MultiBinding which seems to bypass the default converter.</p>
  
  <p>Edit: To expand on the reasoning behind this: I have two objects A &amp; B (of the same type) that I want to edit simultaneously in a TextBox. In the Convert method, I check if they are the same value and either display the value or a default. If the user changes the value in the TextBox, I want the same value to be sent back to both A &amp; B.</p>
