Rav ask me to test latest telerik reporting with latest mono.
I've build mono from sources and tested some basic functionality.
For build latest mono in ubuntu/lubuntu 12.10 you can use this script: https://github.com/jvlppm/build_monodevelop/
Also for run my project you need to build xsp. For doing that you only need to add this line to script: install xsp
I've written mvc project that can generate report on server side and save report as file.
I've tested on simple report, that contains only text. Exporting to pdf not working, but export to MHTML, RTF, HTML working fine.
You can find code here mvc2.zip
For testing you can change format in ReportHelper class:
var pdf = reportProcessor.RenderReport("PDF", instanceReportSource, null);
To run project you need to open solution in monodevelop and run solution. Navigate in browser to http://127.0.0.1:8080/home/exportpdf
File should be saved to App_Data/Reports
I've tested more complex reports, but mono crushed.
I hope with sources you can find why export to pdf not working and maybe make possible to create more complex reports.
P.S. I can share with you copy of my virtual machine with configured mono and mono develop.
P.P.S. in virtual environment lubuntu working faster than ubuntu and fully compatible with ubuntu.
