How do I print multiple devexpress report files at the same time?

To implement this feature, You first need to print the report using the Xtrareport.printdialog and Xtrareport.print methods, and then you need to process the report's Xtrareport.printingsystem Printingsystembase.startprint event.

Key code:

private void Button1_Click (object sender, EventArgs e) {

XtraReport1 report1 = new XtraReport1 ();

Xtrareport[] reports = new xtrareport[] {new XtraReport2 (), New XtraReport3 ()};

Reportprinttool pt1 = new Reportprinttool (REPORT1);

Pt1. Printingsystem.startprint + = new Printdocumenteventhandler (printingsystem_startprint);

foreach (Xtrareport in reports) {

Reportprinttool pts = new Reportprinttool (the);

Pts. Printingsystem.startprint + = new Printdocumenteventhandler (Reportsstartprinteventhandler);

}

Print a report

Pt1. PrintDialog ();

foreach (Xtrareport in reports) {

Reportprinttool pts = new Reportprinttool (the);

Pts. Print ();

}

}

Handling Startprint Events

void Printingsystem_startprint (object sender, Printdocumenteventargs e) {

Prnsettings = e.printdocument.printersettings;

}

private void Reportsstartprinteventhandler (object sender, Printdocumenteventargs e) {

int pagecount = E.printdocument.printersettings.topage;

E.printdocument.printersettings = prnsettings;

If the report contains a different number of pages, and you need to print all pages, follow this step

E.printdocument.printersettings.topage = PageCount;

}
