How to develp a subreport in the same page of the main report and processed when is called

Question

SSRS 2012
Hi guys,
I am developing a report that includes a subreport.
therefore The report is made up by 2 sections:
1) Show a grid (several rows - may be 100 or more - and some columns). It represent high level info  (Each row represent a specific item)
2) The user click on a Row/column (eg: Item1, to see details that must be shown as graph.
Here the problem: Searching info about SSRS reporting for subreports, drilldown, nested report and so on, no ones accomplish the requirements for the following reasons:
1) Subreports: NOT open in the same page. The user must <go back> to see detail for other items, such as Item 2....
2) Nested and DrillDown: Process data as the Main report (they are hidden and displayed after user action). In my case this leads to performance problem, because: if the main report has 200 objects (it means 200 graphs processed and hidden at the same time
for the main reports).
3) DrillThrough and Subreport: The detail data are processed only when the user select the interested item in the main report. Here the problem: the report is shown externally.
Please, it there any possibility to have a subreport (or anything else) to be executed in the same report as the main report and processed only when the user make action?
Thanks for your help.

Hi Fasttrack2,
According to your description, there is a main report with more than 100 rows of summary information, when users click the item of the row, the report need to jump to detail information shows as graph. The problem you are facing is that you are not sure
subreport, drilldown or drillthrough report should be used? You hope to set display detail information in the main report and keep high performance of report.
In Reporting Services, each subreport instance is a separate query execution and a separate report processing task. Subreports are recommended when there are just a few subreport instances. We should not use subreports inside a group when there are many
group instances, instead, consider using drillthrough reports. Drilldown reports process all data even when the data is first hidden. In order to improve the performance of the report, we can split drilldown reports into parameterized drillthrough reports,
because Drillthrough reports do not run until a user clicks the drillthrough link in the main report.
In this case, we can consider using drilldown or drillthrough report. In drilldown report, when we click a plus or minus button to expand or collapse a section of a report, the detail data will be displayed in place. By using drillthrough report, when we
click the link in the main report, the detail data will be displayed, we can come back to the main report by click return button in the drillthrough report.
