Append prepared pages

Ivica · February 2013

Hello,

I'am using this code to append prepared pages from multiple (prepared) reports to new report and show all results in one report preview window (without tabs) and everything works great if report doesn't have subreports. If it does, it throws an exception.

Code:

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â FastReport.Report rep = new FastReport.Report();
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â rep.Prepare();

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â var ind = 0;
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â foreach (FastReport.Report pp in reports)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â {
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for (int i = 0; i < pp.PreparedPages.Count; i++)
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â {
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â var page = pp.PreparedPages.GetPage(i);

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â rep.PreparedPages.AddSourcePage(page);
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â rep.PreparedPages.AddPage(page);
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â rep.PreparedPages.ModifyPage(ind, page);

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ind++;
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â }
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â }

Exception (when report has subreports):

I got this code from expermenting with various solutions and it's most close to that what I need.

Any advice from your side?

Thanks in advance

I was lazy, solution is in programmers manual and on this forum:

Report report = new Report();
report.Load("report1.frx");
report.Prepare();
report.Load("report2.frx");
report.Prepare(true); // Crucial parameter Append=true
report.ShowPrepared();

Sorry for taking your time!
