title: Add button + text in Infragistics ultragrid column
body: <p>I am using Infragistics 2013 version.
  I have a requirement wherein I have to add a button along with a text in a column in winforms ultragrid. 
  The button will open a pop up screen which allows user to select a value that will be displayed as a text in the grid's column.</p>
  
  <p>Thank you.</p>
