title: Databinder.Eval and Substring
body: <p>Im using a repeater control and a databinder to display data from the database to my website.
  example: DataBinder.Eval(Container, "DataItem.title")</p>
  
  <p>Sometimes the text is too long
  Normally I use substring to display the preferred string in length.
  But How do I do this with the databinder 
  And if the text is too long (> 20 characters) I want to truncate it and leave three dots behind.
  How to do that ?</p>
