  When I type something such as "abb",   the "ABB Allentown" value is selected.
  After that, the user press Enter key that value chosen.
  I want to the TAB key work the same way.
  Pls provide the alternative solution to achieve this functionality.

  Hello Bang,
  
  Actually, after some time spent on trying to find solution about your question, I have managed to discover one. You can create a custom MultiColumnComboBox control, which overrides ProcessCmdKey. In this event, if a tab press was detected - use ClosePopup method to close the drop down. Please consider the following code as example:
  

  public class CustomMultiColumnComboBox : RadMultiColumnComboBox

  {

      protected override bool ProcessCmdKey(ref Message msg, Keys keyData)

      {

          switch (keyData)

          {

              case Keys.Tab:

                  this.MultiColumnComboBoxElement.ClosePopup();

                  break;

          }

           

          return base.ProcessCmdKey(ref msg, keyData);

      }

  }

  I hope this helps. Let me know if you have any additional questions. 

  All the best,
