Using iReport, how do you set a variable (could be a parameter, or a value in the REPORT_PARAMETERS_MAP) to Boolean.TRUE at the start of a new band?
There are some fields in the header that should only be displayed after a specific band has started being filled.
Thank you!
AFAIK, it does not wirk that way. It goes straight from the header, passing thru each band header down to the detail band and back to the footer. That's the way one can set sums in the footer of a band, being calculated from the data available at that segregation level. But the filling process for a jasperreports document is pretty straightforward.
In the properties of each text field you have two options available for this issue: "Evaluation Time" and "Evaluation Group". These options can be used to control the filling time of the field.

I'm very new to Jasper Report, and alter an existing jasper report to repeat a field dynamically. The current report is for a cashier receipt, which has in the footer a label signature, followed with a line, on which the client sign the receipt...
now, we mignt have more than a client (1 to 9). Thus, I need to repeat this line as many times as the number of users on the account. (the number of signers is set in field (Java bean) that is passed to the report.
Does anyone have a clue on how to do this?
I fixed the issue and I wanted to share the solution with you. Actually, in my the reason why it didn't work is that I've put my fields (signatures and labeles) in the footer. It turns out that the footer is static. You specify its height once, and it remains the same.
In contrary, the body can be adjusted dynamically dependins on the number of rows you displaying... unless you configure it otherwise.
I didn't try it, but I believe the header works the same way as the footer
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 am using a Cross-Tab object in crystal report. I am having problem making my data column (Field Row) to increase dynamically in height when my data size increases. Since the "Can Grow" property in the Format Editor is disabled, it would not let me set the "Can Grow" to true to enable this function. How do I enable the "Can Grow" function so I can set it to true?
I ran into a similar problem where my row labels did not wrap.
Sadly, I think the best solution is to increase the height of your "data" row field (probably the bottom row). This does fix the height for ALL rows but it means that text in ALL rows will be able to wrap at the same height.
I was going to post an image but I don't have the rep.
Cross-Tabs, like Charts, are always able to grow. For this reason, the "Can Grow"-related formatting options are disabled. It really wouldn't make sense if they couldn't grow since they are dynamic objects.
If you're not seeing some data/rows you would expect, it is because the data is not there or something related to the data source for the Cross-Tab is configured incorrectly.
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 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.
