Print and export formats of Asp.net Crystal Reports

In ASP. NET, the crystal report does not provide the report export and printing functions as in Windows form. We need to add code to control it by ourselves. Here is a demo:

Export:
Myreport reportdoc = new myreport (); // table name
Private void btnexport_click (Object sender, system. eventargs E)
{
Crystaldecisions. Shared. diskfiledestinationoptions diskopts = new crystaldecisions. Shared. diskfiledestinationoptions ();
Reportdoc. exportoptions. exportdestinationtype = crystaldecisions. Shared. exportdestinationtype. diskfile;
Switch (dropdownlist1.selecteditem. Text)
{
Case "Rich Text (RTF )":
Reportdoc. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. richtext;
Diskopts. diskfilename = "D: // demo. rtf ";
Break;
Case "Portable Document (PDF )":
Reportdoc. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. portabledocformat;
Diskopts. diskfilename = "D: // demots ";
Break;
Case "MS Word (DOC )":
Reportdoc. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. wordforwindows;
Diskopts. diskfilename = "D: // demo.doc ";
Break;
Case "MS Excel (xls )":
Reportdoc. exportoptions. exportformattype = crystaldecisions. Shared. exportformattype. Excel;
Diskopts. diskfilename = "D: // demo.xls ";
Break;
Default:
Break;
}
Reportdoc. exportoptions. destinationoptions = diskopts;
Reportdoc. Export ();
}

Print:
Private void btnprint_click (Object sender, system. eventargs E)
{
String strprintername; // specify the printer name
Strprintername = @ "Canon Bubble-jet BJC-210SP ";
Pagemargins margins; // sets the print margin.
Margins = reportdoc. printoptions. pagemargins;
Margins. bottommargin = 250;
Margins. leftmargin = 350;
Margins. rightmargin = 350;
Margins. topmargin = 450;
Reportdoc. printoptions. applypagemargins (margins );
Reportdoc. printoptions. printername = strprintername; // The Name Of The application printer.
// Print the report. startpagen and endpagen
// If the parameter is set to 0, all pages are printed.
Reportdoc. printtoprinter (1, false, 0, 0 );
}
