I have one report with various subreports. These subreports are within a table cell. When the subreport doesn't have any data available, I hide the components (tables, textbox, charts) in that subreport. However, this creates some blank space and I need to eliminate this space.
I already used the properties ConsumeContainerWhiteSpace and KeepTogether, but the blank space is still there.
Any suggestions to remove the blank space?
To hide or show an entire row based on another reports results will be difficult, if not impossible. You will need to get this data in your parent report somehow.
I would create a cut down version of your subreport's query that returns row count for every subreport, but within the parent report. Might look like this:
UserID RecordCount
Abby 3
Bob 0
Carl 1
If you are using SSRS 2008r2 you can then use a lookup function to set row visibility. For example the row visibility expression might be
=IIF(Lookup(Fields!UserID.Value,
Fields!UserID.Value,
Fields!RecordCount.Value,
"LookupDatasetName") > 0,
false,
true)
If an earlier version of SSRS, then join that dataset into the dataset for your table.

am very new to jasper report
also I have tried looking at videos but can not seem to get this one concept
basically there is this main query which i have
select * from table
which is populated in the details area
however i want a second query
select count(*) from table where name = "tim"
and put the count on the footer
can this be done using jasper
any tutorial to this concept or guidance would be helpful
to sum up the details area should show all the data where as the footer should only show counts of a few things.
You can only have one DataSet (therefore query) for the report. In your case this is your main report select * from table, which seems to be working well.
You have two options for adding the information you want:
(and I would say the better option) is to add a variable $V{tim_count} which is configured as:
initial value 0
expression value "tim".equals($F{name}) ? 1 : 0"
calculation function sum
there are multiple ways to increment this variable, so I'll leave that with you. In the footer you would then add a text field with the $V{tim_count} variable as it's contents.
You can read about variables here https://community.jaspersoft.com/wiki/variables
You can add an object that has it's own DataSet:
Table
List
Subreport
You would then be able to add your query to that object and display it appropriately. As you can see, displaying a COUNT is not really the most appropriate way to do this.
Note - I don't suggest this way
I have created a report as follow:
Multiple detail band
each detail band contains 1 table. Each table is linked to 1 dataset.
Can I hide the detail band whenever the result set of the query returns Empty set (no result found)?
how can I achieve this?
In the "Properties" of each Detail band you have an option called "Print When Expression" there you can place logic that evaluates to boolean.
When you fill it with your logic and it returns true this detail band is printed.
So, you will need to have the information if the table will be filled in advance and cannot address the dataset within.
If your datasets are too different to do this, you should overwrite the Dataset for the main report with a custom one that gathers the information and sets the fields appropriately.
I have to create a report where several tables are diplayed below each other. Each table gets its data from a SubDataset and contains none, one or more rows.
For the first version of the report, I've simply ignored the possibility of a table having no rows and put all tables below each other, each with the height of 1 row. The idea was, that if there is more than one row, the table will grow in height, which seems to work fine. I've given the first table a fixed position and set all subsequent ones to float. In iReport it looks like this:
But when I create a report, only the first table is at the expected position. The rest is displayed too low and overlaps:
Any idea how to fix this? I can't use subreports, because the report is stored in a database so I can't reference other reports. Is there maybe another alternative to subreports or tables?
You have the "Position Type" property set to "Fix Relative to Top". Change it to "Float".
Try looking into using subreports. I do create table followed by another (datasource is XML).
create subreport using xPath
Use Data Source Expression property of the subreport to set the datasource for subreport
((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/FUND_STATEMENT/FUNDS/FUND")
I have added a subreport to my report. The aim is simply to hide the subreport if there is no data in it.
NoRows property was mentioned on this thread on Microsoft forums, but I guess it is for SSRS 2005 as the thread as quite old.
Isn't there any obvious way to hide subreport if there is no data in it? I could hide the tablix in the subreport itself, but I also need to hide the row where subreport placed. To do this I need an indication whether the subreport has data or not in the main report.
Could you give a clue to sort this out?
I had a similar problem a year ago or so. My vague recollection of this:
The default behavior as I recall was that SSRS won't show the subreport if the datasets in the subreport return no rows. This accomplishes half of what you want, but doesn't let the parent report know whether to hide the subreport area or not. IIRC, the NoRows property only controls what will be shown in this case, but it's not easily checked at run-time to change other properties.
My final solution was to create a stripped down query in the parent report that would indicate whether or not the sub report would have any rows. I used this to control row and subreport visibility.
I suspect there's a more elegant answer...
I placed the subreport in a row of its own. Then I edited the rdl file in a text editor and set the row height to 0 (The designer will not let you do this).
With the row height at 0, the row is practically hidden, until the subreport gets data, at which point, the subreport determines the row height, and it all looks normal again.
An alternative to editing the rdl may be to set the height of the row in code, I haven't looked into that though.
I ran into this issue and none of the answers worked for me. In my case I was converting a Crystal Report to an SSRS report and was using a sub-report that could occur for every group. This was fairly simple in Crystal Reports because you could suppress empty sections with a checkbox.
What worked for me in SSRS and was very clean was to add a subquery/CTE to my main report query that got a count of the number of rows that would be present in the sub-report data. For example:
SELECT CommonCriteria, Count(*) [RowCount]
FROM TableUsedInSubReport
GROUP BY CommonCriteria
Then just join this subquery/CTE to your main query on the common criteria. Once you have this it is very simple as you just right click on the far left of the row in the tablix and select Row Visbility. Then you use an expression such as...
=IIF(Sum(Fields!RowCount.Value) > 0, false, true)
That way if there are any rows to display in the sub report it will display them and if there are no rows in the sub report it will hide it and not leave white space.
i ended up using rectangle underneath the subreport - that way if subreport returns nothing, rectangle underneath it will control appearance of the cell - in my case I needed to grey out the cell if subreport returns nothing.
This thread gave me an idea How to supress empty subreports in SSRS 2008 but I did not even have to use expressions because by default SSRS won't render subreport if it returns nothing.
The more easy solution is:

Hello,
I had just run into this issue myself. The ugly error along the lines of "Error: Subreport could not be shown" was really annoying me.
Solution:
To solve this, I simply nested the subreport within a rectangle and used an expression on the visibility for that rectangle like so.
ex.
=IIF(Fields!Field1.Value IS NOTHING,true,false)
(Field1 in my case was a returned data column from the parent report.)
Make your changes accordingly :)
I'm trying to create a report using iReport-3.6.7 IDE. I've added a dataset which I used for filling the values into a Table in the report's Details section. Everything is fine with the report compilation. But problem is that when I run the report in the IDE, it displays entire values as much is the number of tuples in the source table. i.e. if my table in source database has 16 tuples, then in iRepoort IDE the table is repeated 16 times. Please, don't tell me I'd place it in other sections e.g. Table Header, Table Footer, etc.
The problem was caused due to my bad approach to report design. Since everything we put into the Detail band of iReport gets populated at run-time, my table (which I'd put in Detail band of report) got populated as many times as of the tuple returned by the report's query.
I had the same problem, I fix it, editing the query SQL in the subreport 1 in the header space, ande the supreport2 in the detail space, if your table is large and you put in the header space , then will give you an error like this "infinite loop creating new page due to column header overflow"
make false "print Repeated value" By Selecting particular Field
