• • <%= is the equivalent of Response.Write()
  • <%# is for Binding Expressions on Data Bound controls.
  • <%$ to access AppSettings, ConnectionStrings and other values contained within an application's configuration and resource files
  Michael Stum : For <%$, i'd like to add that Phil Haack has an excellent post about creating your own Expression Builders: http://haacked.com/archive/0001/01/01/Express_Yourself_With_Custom_Expression_Builders.aspx (Also read the comments)
