I have a problem with JasperReports' report. I want to create a report that produces for each Database entry, on sheet. When I create it, it shows me only a few rows. Maybe there is a parameter to set in the iReport designer.
A number of things to check:
Change the height of your report. Do you get more rows to appear? What about the height of your band? Does it change the results?
Check which band you have your content in. Some bands behave differently than others. Header/Footer/etc bands do not expand.
Check your input (the data from your query / xml datasource / whatever). Make sure that what you think is the input to your report really is.
Otherwise, likely we'll need more information. If you could upload an example jrxml that would help.

I am very new to jasper reports so please bare with me. I created a new jasper report using the "tree" template. I simply used a table that has ~50 fields (select * from mytable). Jasper reports created the report. I made no other modifications, whatever jasper studio generated is the fie I have. It seems to have a height of 1420px. The columns are on the left, the values are on the right. When I go preview the report now, I get the error message:
the detail section, the page and column headers and footers and the
margins do not fit the page height
I understand that there are so many columns, it is to large for the report, but do not know how to solve it. I would like the report to automatically start a new page whenever the data fills up. I do not know the exact heights these fields will have as it depends on how much text is inside of each, which depends what is stored in the database. How can I accomplish so that the report automatically starts a new page when it needs to?
I have created a report using ireports and add the text fields in Summary band to display the Average values .
I am able to get those in pdf , csv formats but unable to display summary band fields in Excel.
Can anyone please help me.
Thanks in Advance
You probably have an answer by now, but I've seen this happening if the fields dimensions overlap. Check the settings for each field. In iReport/Jasper Studio, go to Properties and check width (w) and height (h) values
and make sure they align properly (no overlap).
Requirement:
I have one new requirement in Crystal Reports.
I need to show 100 columns in the report. I have tried using Landscape option but maximum I am able to accommodate are 20 columns.
Can someone have any idea on how can I accommodate 100 columns. Thanks in advance.
Practically it is not suggested to take 100 columns..as this can create an issue while monitoring the data in crystal reports
But if you still need to accompdate the 100 columns then follow below process.
go to File --> Page Setup --> there go to Unit --> for selected option give maximun size for Horizontal Component
This will increase the size of the report and now can insert required number of columns
Since this report is not for print and will be exported into an Excel format, just make your page as big as you need it. This can be done by going to "File" → "Page Setup" and adjusting the following things:
Check "Dissociate Formatting Page Size and Printer Paper Size"
Might as well flip the page to "Landscape"
Enter a large number in "Horizontal"
You should also note that because you're exporting this data (especially as "Excel - Data Only"), you don't need to make the columns wide enough to display; as long as the field is on the canvas they should show up as a column.
The size of the columns doesn't matter if you are going to export to Excel data only. So you can make the columns as small as you want, even if the report is not readable it will be exported OK.
If you want just to export some data and your report does not include subreports you can go without Crystal reports. Will be much simpler to set the SQL and preview data in a grid (which is scrollable) and then export it to Excel. It will look better too.
There are some tools that can do this and I guess you can easily find something on Google. I am using R-Tag (www.r-tag.com), which is free. You can see it in action here: http://www.r-tag.com/Pages/Preview_Demo.aspx
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:

=IIF(RowNumber(Nothing)>0,False,True)

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 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.
