Hi Chris,

Javascript can be used to provide the formatting you need.

string DisplayPhone(string s) {
   return s.Substring(0,3) + "-" + s.Substring(3,3) + "-" + s.Substring(6);
}

You can call a helper function inside a "<%# %>" construct like so:

<%# DisplayPhone(DataBinder.Eval(Container.DataItem, "Phone", "{0}")) %>
