I am using iReport 3.7.6 to create this report.
I have a report based off of an XML file. There is a 2-column master report and it has a detail band with a subreport.
I have a field called "Name" in the subreport. I want it to print at the top of every page. Or even at the top of every column. I have tried virtually everything I know how to do.
"Print When Detail Overflows" doesn't work, because this setting is in the detail.
I sure hope I don't need to create a subreport for every report break I want. I'll have like 4 or 5 subreports.
Is there some way to determine when the page has changed, and then use that event in a "Print When" expression?
Here is one solution, presuming the value does not change between pages:
Write a query for a subreport that obtains only the Name value.
Change the dimensions of the subreport to be as small as necessary.
Place the subreport in the page header band of the master report.
To answer your question accurately, more details (such as pictures of what you have versus what you want) would be helpful.
you can use pageCount variable which is implicitly available in jasper reports to know whether the page has changed or not.

I am new to JasperReports, basically I want to put a subreport in a mainreport
The problem is that I put the sub report in the Detail band, so when I query a database that has multiple data the subreport will always repeat itself multiple times when I output the report to a pdf. I want a report that does not repeat itself regardless of how many data I have in the database that i connect with
I have searched the Internet and the solutions is to add
new Boolean($V{REPORT_COUNT}.intValue()==1)
in the print when expression attribute of the subreport, that does solve a part of my problem due to the fact that now my subreport only prints once but it still leaves some blank pages after my subreport is displayed
So I assume it is still repeating itself but just doesn't print the data because of the expression that I added , people say that the nature of the detail band is supposed to work that way and that I shouldn't put the subreport in the detail band, but if I put it in some other band I get this error:
Error filling print... Subreport overflowed on a band that does not support overflow.
The error above will happen if I have a lot of data to the extent that it may take up more than a page.
How do remove those blank pages? If I am ask to not put it in a detail band then what should I do? or what solution are there?
The Detail band will be generated as many times as the number of records you have in your main dataSet(populated by the top-level query).
If you want to keep the subreport in the Detail band, which is normal by the way, you can do one of these things:
either have a dummy query that returns only one record, so that the Detail band generates only once. Then, pass the report connection to your subreport. You may have done that already. This way you can run your query independently of the main report.
or leave the report as-is and add your printWhen expression ($V{REPORT_COUNT}.intValue()==1) directly on the Detail band, not on the subreport. Please note that this is just an ugly hack that may affect the report performance. Your main query still returns a lot of data that you don't use so you should consider the other options.
If you can move the subreport out of the Detail band, place it in a band that allows overflow like Title or Summary band. Then:
have your main dataSet's query empty so that no Detail band gets generated
set whenNoDataType="AllSectionsNoDetail" at the report level(in the <jasperReport> tag) so that all the other sections except the Detail get generated
exactly as in the first option above, pass the report connection to your subreport and work from there

Crystal Reports: including a subreport into a grouping section?
asked the same question, but I am hoping a comment on the accepted answer is wrong: that it can't be done because the subreport must be in the details section. Also, what the selected answer says to do isn't working (perhaps because of the other detail, no pun intended).
So this looks like a duplicate question, yet the original question does not appear to be answered, and certainly the accepted "answer" is not usable by me.
(see also How to handle a duplicate question when the original has an accepted answer that is not really acceptable?)
My subreport can list one to many items, each of which can join to one or more items in the main report details. The common field they join on is the grouping item. So, for example, the subreport might have three items and the details five, but if I put it all in the details, I would have fifteen rows, with the first part repeated five times and the second part three times.
The common item appears as a "command field", a "report field". and the Group item. But no matter which of those I link as a subreport parameter, the subreport gets nothing and asks me to enter a value when I try to view the report.
In a more recent version of Crystal Reports you have two options: You can either connect the subreport to a value on the main report via the subreport parameter dialog. or you can pass a Shared Variable between the reports. If you are using the subreport parameter dialog, then the value passed in will be whatever that value is at the time the group is displayed. If the value comes from a detail in that group or from a variable on the main report it shoud pass fine. If the value is something that would be displayed after the group is displayed on the report (going top to bottom) then the value won't be written yet and will be passed to the report as null or blank.
Shared Variables are shared between a report and all of its subreports. If you need to get data from a subreport or pass a single value to multiple subreports, it might be the better option. If the shared variable is changed in the report or a subreport, it'll use the new value in everything after that.
SAP has a good guide on both techniques here:
http://scn.sap.com/people/ashish.bamzai/blog/2011/11/23/passing-values-between-reports-crystal-reports-2008
Bear in mind that Crystal Variables are always populated based on their position in the report and the order they are printed in. If something needs to happen after another group or subreport prints, you'll need to use the WhilePrintingRecords keyword.
I am struggling to fix a subreport where data is obtained at the point when the main report is generated and the subreport to be displayed as a link, similar to an on demand subreport.
The issue that I have if I use a non on demand subreport is that it cannot be represented as a link, it is displayed inside the main report. As well as an on demand report is not suitable to my case because the data is retrieved when the subreport is opened.
I would appreciate any help.
Thanks in advance!
You have to take the another header for subreport and also drilldown the Header and on the Suppress formula write the formula Drilldowngrouplevel = 0 and for the Sub Report take the another detail section and on the supress formula write the formula Drilldowngrouplevel = 0.
This will definitely work, because I tried it.
Can you add a group level to the subreport and add a single line into the group header?
This will mean you will have to drill down twice to get the data though.
I need to include or exclude a subreport based on a condition. I'm using iReport to create JasperReports. I.e., if a subreport has values, I need to include that subreport, otherwise not. Can anyone please send a sample or tell me how to resolve this.
you can in the master report get data from your data source that allows you to identify if the subreport should be included, then use the 'printWhenExpression' field on the subreport element to check that data.
I use this regularly - for example the printWhenExpression field may contain:
new Boolean($F{TOTAL_STATS}.intValue() != 0)
where TOTAL_STATS is from the master report's database query. If non-zero we show a subreport detailing some data.
From my knowledge, if there aren't any data printed in the subreport, Jasper eliminates the blank space. In other words, if your subreport would normally occupy half a page, but there is no data, then the empty space is eliminated. I'm not sure this is what you mean by including or excluding the report.
Another solution would be to place the subreport in the main report, and from right-click ->properties -> Subreport tab, you select the "Subreport condition" tab and write your condition there. If the condition is true, the content of the subreport will be printed, otherwise it won't be printed.
Jamie Love's answer about "printWhenExpression" is on target.
if there aren't any data printed in the subreport, Jasper eliminates the blank space
Actually, at least in JasperReports 3.7.0 there is a subreport property "Remove Line When Blank" that controls that behavior. By default - at least when I use iReport - that parameter is off.
