title: Infragistics Ultragrid valueList/UltraDropDown
body: <p>What event to I need to handle to allow users to add "fruit" the either a valuelist or ultra dropdown.</p>
  
  <p>Since it is a KVP I always get format exception</p>
  
  <pre><code>Dictionary&lt;int,string&gt; fruits = new Dictionary&lt;int,string&gt;();
  
  
  
   private void FruitInit()
       {
      //Create some fruit        
      fruits.Add(-1,"apple");
              fruits.Add(-2,"banana");
  
              //Create and add to the ultraDropDown
              UltraDropDown fruitUltraDropDown = new UltraDropDown();
              fruitUltraDropDown.DataSource = fruits.ToList();
              fruitUltraDropDown.DisplayMember = "Value";
              fruitUltraDropDown.ValueMember = "Key";
              MyUltraGrid.DisplayLayout.Bands[0].Columns["MyColumn"].ValueList = fruitUltraDropDown;
          }
  </code></pre>
  
  <p>What event can I handle so when a user types "grape" I can add it to the dictionary with my own key, and it gets added to the dropdownlist. Currently if I type "grape in the cell, I just get a format exception. </p>
  
  <p>Regards</p>
