Hi is there any way that i can load subreport in runtime.
I have one main report on which i would like to load different subreport.
this subreport can choose end user throug parameter or something else
If i can programatically set subreport filepath, or filename or somehow else dynamically set which subreport will be shown, that would be great.
thanks for help

I am not certain you can call a subreport that is not part of the main report. My understanding is that the main report acts as a container for the subreports.  I am not aware you have the abililty to set a subreport path in code.  

As a fall back, what you might do is create subreports and then suppress them until needed. If you have a large report and need a lot of subreports the performance could be impacted.
 
You might also look at the dynamic subreport features, where the subreport does not run/show until its link is clicked. I dont know if this opens up a way to dynamically change the reports.
 
Sorry I can not be of more help.  Perhaps others will have better solutions.

I haven't done this before, but if you have CR R2 Developer, then you can add subreports dynamically with the report document object object. This is part of the new licensing that comes with R2 Dev. I suggest downloading the 30 day trial version and testing that out before making a purchases.
