Progress bar for generating reports

[Esemtia Grupo Edebe]

Hello guys,

I'm programmer, and I'm working with telerik reporting in my proyect of visual studio C# 2013. We work for very complex reports, and we generate them programmatically. 

I attach an example of rerpot class ("ReportExample.PNG"), another example when I build this report ("callReport.PNG") and an another example of my function to export PDF ("exportToPDF.PNG").

Normally the reports take a long time to generate in pdf. I suppose that this time in total corresponds to the time it takes to generate the report + time to build the pdf. 

I would like to be able to show a progress bar so that my clients can see the time that the report requires to obtain it. Is there any function within telerik reporting to do this functionality?

Regards
