In window Field Explorer-> Parameter Fields->nameField->Edit->"Edit a parameter and list of values " of Crystal report,  I want a drop down menu with all of the values of  my table for my parameter for users to choose.  In option "Action", I choosed "Append all database value". There it works, It add all value from table of database.
