body: <p>I am creating infragistics wpf grid at runtime.</p>
  
  <p>in FieldLayoutInitialized i am creating unbound fields.</p>
  
  <p>one sample unbound field is</p>
  
  <pre><code>UnboundField field = new UnboundField();
  
  field.Name= "Testfield";
  
  field.BindingPath = "Binding path";
  
  FieldLayout fieldLayout;
  
  fieldLayout.Fields.Add(field)
  </code></pre>
  
  <hr>
  
  <p>But my requirement is i have a field which is calculated one so for that i created converter. converter will return sum of two values.</p>
  
  <p>A3 = A1+A2;</p>
  
  <p>If it is from XAML file we can write like</p>
  
  <pre><code>&lt;Textbox.Value&gt;
  
  &lt;MultiBinding Converter="{StaticResource ConvertnameClass}" Mode="OneWay"&gt;
                      &lt;Binding Path="A1"/&gt;
                      &lt;Binding Path="A2"/&gt;
                  &lt;/MultiBinding&gt;
  &lt;/Textbox.Value&gt;. 
  </code></pre>
  
  <p>field.Converter = coverter class object;
  field.ConverterParameter = ???;</p>
  
  <p>if it is single binding we can send the
                  field.BindingPath = "class prop value";</p>
  
  <p><strong>how can i send multiple binding values to converter from code behind when it is creating run time.</strong></p>
  
  <p>please help me out.</p>
