In addition, you can import the data of dataset to the Crystal Report, and then import the data to PDF, Doc, XSL, HTML, etc for printing. below is the method
Crystalreport1 myreport = new crystalreport1 ();
Sqldataprovider = new sqldataprovider ();
Myreport. setdatasource (sqldataprovider. runprocdataset ("show_authors"). Tables [0]); // sqldataprovider. runprocdataset ("show_authors"). Tables [0] is a datatable
Crystaldecisions. Shared. diskfiledestinationoptions diskopts = new diskfiledestinationoptions ();
Myreport. exportoptions. exportdestinationtype = crystaldecisions. Shared. exportdestinationtype. diskfile;
// Myreport. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. portabledocformat; // PDF
Myreport. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. wordforwindows; // here is word
Diskopts. diskfilename = "C: \ output.doc ";
Myreport. exportoptions. destinationoptions = diskopts;
Myreport. setdatabaselogon ("sa", "hyaocuk! "," 127.0.0.1 "," pubs ");
Myreport. Export ();
