title: Multi-Column ComboBox Controls for Winforms
body: <p>Please recommend some Multi-Column ComboBox control for Winforms application in .net. Better if they are free.</p>
  
  <p>I found <a href="http://www.syncfusion.com/products/user-interface-edition/windows-forms/tools/multi-column-combo-box" rel="noreferrer">Syncfusion - Multi-column-combo-box</a> it can show datagrid which is bound to datasource but it is not free.</p>
  
  <p><strong>EDIT:</strong> There is an awesome control used in inFlow Inventroy, please also tell if you know something like this</p>
