Is there any way to refresh a subreport in Reporting Services?
When I change something on a subreport file and back to the main report, I have to delete the subreport object and include a new instance again to get my preview updated.
Is there any way to update the sub report object in the main report without having to delete and include the same again?
Actually I think the answer is to ensure that you preview or rebuild the sub-report before you view it in the parent report.
The simplest way to rebuild a subreport is to preview it in BIDS, but you can also right-click | build on the report in the Solution Explorer. Alternatively, rebuild your whole report project if that's easier than rebuilding individual reports.
In BIDS, in your top level report, you should have a Subreport object. That object is essentially just a pointer to another rdl in the project. This should update automatically. What i think you're seeing is BIDS loading a stale version of the subreport. If this happens try closing BIDS all the way down and open the project back up again and rerun the parent report. It should have the updated subreport.
This is all assuming that you've got a report project in bids with standalone reports instead of embedding reports in aspx pages.
I realize this is an old post, but as can happen, I was someone with the issue as well and landed here through searching google. I'm not sure if the OP is using Visual Studio 2008 like one of the commenters is, as am I, but what I found is that while preview on the main report is not showing an updated sub-report, I can see the update by right clicking on the main report in the solution explorer and selecting "run". It doesn't seem to take much longer if at all to open the separate run window.

Ok, I have an SSRS report that has 2 subreports in it. One works just fine and the other works in testing but when I publish the report to my AMS platform under their instructions, the subreport comes up saying it can't be found. I can run the report through Visual Studio and it works just fine without a problem and I have rebuilt the entire project a few times and republished but I still keep getting the same error. I know that the publishing is working because I made a change to the main report to expand the subreport area and allow me to see the full error and that published fine. Any reason this would work through Visual Studio but not when published? The report along with the 2 subreports all are in the same directory as well.
Additional note to this. I just went to the master report in Visual Studio and deleted the subreport from it. I then re-added it and gave it a different name. Rebuilt the report and re-uploaded it including the already uploaded sub report and I am getting the same error but the error is referring to the new name I gave the subreport so it picked up the name change but not the actual sub report for some reason
Sometimes SSRS website caches your old report and doesn't get overridden by your new reports. On the SSRS website, try removing all of your reports including the main report. Then re-deploy.
I have around 10 SSRS reports (i.e. 10 .rdl files) and those needs to be exported to one PDF. How can I do this? Do I need to write custom C#.Net code or SSDT 2017 provides any simple feature to export that?
Please note that, all the RDL files has different header and footer, The 1st page has image in it,few pages has both tabular as well as matrix report.
As suggested, I have one main report and I'm adding sub-report one after another (just maintain the sequence)
I searched on MSDN, however, it looks like Microsoft does not have such feature till now OR may be I'm missing something? Or any special setting or .Net code needs to be written?
Note: I have two version of SSDT (2016 and 2017)
You could just create a master report and then put your 10 reports in that as subreports.
If you reports take a parameters then all the parameters will have to be setup in the master report and then passed to the sub report.
Then, just run the master report and export to PDF...
I have used a Guage as a clock. It is set to auto-refresh for every 3 sec.
It is running properly, but whole report is refreshing, reloading. So cant get a feel of a clock.
So I tried to use this (Clock) report as a sub-report in another report (say main report) which is not set to auto-refresh.
I am not getting why my sub-report is not auto-refreshed in main report.
Ideas & Hints are welcome!
I've never used the auto-refresh property of a report but I would guess that since it is a report-level property what you're expecting to happen won't work. In order for only the subreport part of the report to refresh it would effectively need to be a frame or iframe (using HTML as a reference). SSRS does not render this way and so your subreport isn't going to autorefresh. It renders the subreport and shows it in the subreport control and moves on.
I'm not really sure how you could have a dynamically updating element in a report using the standard controls. It would need javascript or some kind of other client-side scripting language that gets processed in order to keep functioning and even then it would only work when rendered to HTML.
Basically I don't think this is possible without a third party add-on, and I don't know of one that allows dynamic refreshing of individual report elements without refreshing the whole report.
If you can program in .NET you could write your own custom control for SSRS. This is effectively a third party addon you would create yourself. You could create a clock control and even give it properties to make it customizable. If you're going to use it in reports that you deploy to a report server you'll need enough access to that server to deploy the control assembly to the necessary location.

I am building a report with one "go to report" and in that new report I have one subreport. Now, when I´m sitting and working with the report and for instance changing the format for a cell the report doesn´t view the new changes directly. Sometimes it does. Sometimes I have to wait a while, sometimes I restart BIDS. Has anyone experienced this problem before?
I think the way VS maintains subreport data when designing means the definitions can get stale; does a Rebuild Solution before previewing help?
This should hopefully make sure everything is up to date and for a Report project/solution it should be quick to rebuild.
In SSRS 2008 R2, I was under the impression that a drill down to a sub-report would query the data on-demand.
This isn't the case when my report gets rendered.
Specifically, I have a Tablix that initially loads rows grouped by Person.
When someone clicks the drilldown icon on that Person, a subreport displays some more data pertinent to that Person.
The problem here is that every subreport is being loaded initially when the main report is being rendered. This takes forever to load. But if I remove the subreport, just for testing purposes, the report loads almost instantly.
I've tried setting the visibility of the subreport to Hide initially, then Show when the user drills down, but it didn't change anything.
I read a similar question on stackoverflow, but the answer was to use Drill-Throughs instead.
This unfortunately isn't an option in my case.
Any suggestions?
The only way to defer the data loading is to actually use a new report with and access it via Drill-Through method. This is the way to product work, and is the way inteded by Microsoft.
You can either optimize your stored procedure, limit the number of results per page or use drill-through.
