Question regarding the rendering of subreports

[tpontow]

Hello Stimulsoft,

i have a question regarding the rendering of subreports. I noticed some great difference in rendering performance when using subreports. But let me explain in detail:

First of all i created a report with one data band on the main page Page1. I connected the data band to a business object and at runtime i registered a list with 60000 items to that business object. With that the report is rendered in about 13 sec with 958 pages. Everything fine so far.

Now i placed another data band on the main page and added a subreport to that data band which has no data connection. Now i moved the first data band (the one that is associated to the business object) from the main page to the subreport page.

• With that constellation
  • Page1
    • DataBand with no data association
      • Subreport
        • DataBand with business object

the rendering of the 60000 items business objects list lasts very very long.

In the end the output result of the 2 report variations is exactly the same. Is there a way to accelerate the rendering of the subreport data band?

Thanks and regards
Thorsten Pontow

Hello Aleksey,

thanks for your quick response. Currently i'm using build version 2013.2.1606.0 from 24th May 2013. I soon will switch to the latest prerelease build and will compare the rendering times again.

Hello Aleksey,

i changed to build 2013.2.1611.0 from UL_2013.07.01 but the rendering is still very slow when using the subreport. About 8 min for 100 pages.

Hello,

i never tested it again since my last post. Meanwhile we changed to Version 2014.1.1801.0. I will check the performance the next days and will report the outcome.

My solution for the problem so far was simply to minimize the number of subreports.

Kind regards
