The VO contains values for the fields in the sub report and other 5 sub repports in the sub report. The main report will call the sub report for each vo in the arraylist. We need each record to be displayed in separate pages in the same PDF. There are cases that the 5 subReports in the sub report won't be displayed only the table in the sub report will be displayed. We need each record to be displayed in separate pages regardless of whether the sub report contains other 5 sub reports.
We tried to put a page break after each record so that the next record comes in separate page but we got an exception element type 'break' must be declared. Please help us to solve this issue.

Like other data aggregating elements charts, for instancethey are organized as regular report elements, but with a complex structure and granularity. Crosstabs can be used with any level of data nominal, ordinal, interval, or ratioand usually display the summarized data, contained in report variables, in the form of a dynamic table. Variables are used to display aggregate data such as sums, counts, average values. Crosstabs are also interesting due to their flexible layout capabilities.
When a crosstab does not fit on a page, then either a column or row break occurs, and the crosstab splits into several pieces. Depending on the remaining available space, the crosstab could continue on the same page, or it could overflow onto a new page. A crosstab element is characterized by the following attributes: isRepeatColumnHeaders - indicates whether the column headers should be placed in front of columns each time a row break occurs.How to create report group in Jaspersoft Studio
The default value is true. The default value is The default value is LTR. The default value is false. Crosstabs are also able to represent standalone data, not contained in variables.
Any number of dynamic values can be passed from the enclosing report to the crosstab as crosstab parameters. Crosstab Datasets Like charts, crosstabs can handle by themselves collections of data. They can access data either in the report main dataset, or they can handle their own subdataset. To faster perform calculations on data it is recommended that data come already sorted within dataset, according to the row and column groups.
If this is not the case, then the crosstab internal engine should be instructed to sort data during the aggregation process. One can do this using the isDataPreSorted dataset attribute. More on datasets can be found further in the datasets section. Data Grouping in Crosstab The crosstab calculation engine aggregates data by iterating through the associated dataset records. In order to aggregate data, one need to group them first. In a crosstab rows and columns are based on specific group items, called buckets.

When the column is hidden, the space it would have occupied is left blank, which is not particularly attractive. In theory, I could achieve the first by setting the width of the column and header to 0, but also indicate that the column should resize to fit its contents.
But JasperReports does not provide a "resize width to fit contents" option. But that seems like a lot of effort for such a simple requirement. In later version v5 or above of jasper reports you can use the jr:table component and truly achieve this without the use of java code as using dynamic-jasper or dynamic-reports.
JasperDesign is used to modify the template object JasperReport from within the code at runtime. I guess this might fit in your case. A slight variation on the "second report" theme that I have used is to isolate the part of the report where you have an optional column into it's own subreport, and then create two subreports, one with and one without the column, and then use conditions to determine which subreport to print.
Remove line when blank: This option takes away the vertical space occupied by an object, if it is not visible; the element visibility is determined by the value of the expression contained in the Print when expression attribute.
Think of the page as a grid where the elements are placed, with a line being the space the element occupies.
Figure highlights the element A line; in order to really remove this line, all the elements that share a portion of the line have to be null that is, they will not be printed. I recommend to use DynamicReportsit's open source and based on JasperReports. The main benefit of this library is a dynamic report design and no need for a visual report designer. If it is just one column, is it possible to place this column to the far right, and then use the print when expression. That way there is not a hole in the middle.
I know this is not ideal, as I had tried to do what you are currently trying to accomplish in the past, and could not find what I call a good solution. A second idea would to be create a second report based on the first with out the column, and then when calling the report check the condition, to decide which one to call. Again not ideal, but would work. I know this is not really the answer you were looking for, but one of these suggestions may work for you.
This is pretty complex.
And to make it simpler you can us DynamicJasper. I guess this answer comes way too late, but I add it for the record. In my case I could solve it without any additional dependencies or tools. Once per possible width that is. Then on each textfield, I have set that it should only be printed in case of a certain condition. This might not be as elegant as setting the width dynamically, but it does the trick without any hassle with extra libraries.

I would prefer if the extra space was used in a more effective manner, possibilities include: the width of the report is reduced by the width of the hidden column the extra space is distributed among the remaining columns In theory, I could achieve the first by setting the width of the column and header to 0, but also indicate that the column should resize to fit its contents.Crosstab cross-tabulation reports are the reports containing tables that arrange data across rows and columns in a tabular form.
Crosstab object is used for inserting a crosstab report within the main report. Crosstabs can be used with any level of data nominal, ordinal, interval, or ratioand usually display the summarized data, contained in the report variables, in the form of a dynamic table.
Variables are used to display aggregate data such as sums, counts, average values. The default value is true. The default value is The default value is LTR. Else it will stop rendering columns within the crosstab width limit and continue with the remaining columns only after all rows have started rendering. The default value is false.
Mapas a set of parameters for the crosstab. This element contains no attributes. Default value is false. The size of this cell is calculated automatically based on the defined row and column widths and heights. Default value is Nothing. The crosstab calculation engine aggregates data by iterating through the associated dataset records. In order to aggregate data, one needs to group them first. In a crosstab, rows and columns are based on specific group items, called buckets.
The current value of a measure calculation is stored in a variable having the same name as the measure. Here, we will add the crosstab to summary section. Here, each row will display data for a different name.
Here, we used the name field as a delimiter, in order to split the rows by name. The calculation attribute is set to Count. The java codes for report filling remains unchanged. Next, let's compile and execute the above files using our regular ANT build process.
The contents of the file build.You can control whether to repeat row and column headers on every page of a Reporting Services paginated report for a tablix data region a table, matrix, or list that spans multiple pages. How you control the rows and columns depends on whether the tablix data region has group headers.
When you click in a tablix data region that has group headers, a dotted line shows the tablix areas, as shown in the following figure:. Row and column group headers are created automatically when you add groups by using the New Table or Matrix wizard or the New Chart wizard, by adding fields to the Grouping pane, or by using context menus.
If the tablix data region has only a tablix body area and no group headers, the rows and columns are tablix members. For static members, you can display the top adjacent rows or the side adjacent columns on multiple pages. Right-click the row, column, or corner handle of a tablix data region, and then click Tablix Properties. On the design surface, click the row or column handle of the tablix data region to select it.
The Grouping pane displays the row and column groups. On the right side of the Grouping pane, click the down arrow, and then click Advanced Mode.
The Row Groups pane displays the hierarchical static and dynamic members for the row groups hierarchy and the Column groups pane shows a similar display for the column groups hierarchy. Click the static member that corresponds to the static member row or column that you want to remain visible while scrolling. The Properties pane displays the Tablix Member properties. If you don't see the Properties pane, click the View tab at the top of the Report Builder window and then click Properties. As you view each page of the report that the tablix data region spans, the static tablix members repeat on each page.

Tables plays a very important role in every designin iReports Tables are used to represent data in an efficient and usefull manner. Most of the time we need to iterate our dynamic data to display the outputin case of iReports this is done by Tables and Datasets. The following are the basic steps we will take:. Provide a name to Dataset and let the first radio button selected for nowclick next. Now click next :. Let this page empty as it for nowand click on Finish.
Here we are done with Datasetwe can review and edit it from out Report Inspectoras shown in below image :.
Now we need to connect our Dataset to Tablejust select appropriate Dataset from drop down list and click next :.
Here we can select a db connection for our Tablelet the very first radio button be selected for nowclick next :. Here we can set layout and design for our tableclick finish and we are done with it. Here we can add Headings and Data Fields to our table. In Main Reporst we can see an Table Icon like thistable position in the Report can be adjust from here :.

However, if needed, multiple documents with particular page settings can be concatenated to produce a single document output with different page layouts, using the batch export facility. In the case where no batch export is implied, all document pages share the same page settings, and they are by default separated by page breaks.
At export time each exporter has its own way to handle the page break element in order to make visible the page separation. But there are situations, especially for web-oriented applications, where pagination is irrelevant and it causes the document to be displayed improperly.
For instance, when exporting documents to HTML format, one might prefer to display it as a continuous scrollable page rather than a succession of pages separated by visible empty spaces. Or, when exporting to Excel in a single sheet document, a layout without visible page breaks would be preferred. This is why the engine needs to be instructed how to handle page breaks in various situations.
A possibility would be to completely ignore the pagination, with no respect to the output document format. Responsible for this kind of approach is the isIgnorePagination flag property. Running the generated report to any output format, a single page document will be visualized. By default, isIgnorePagination is set to false. And this layout will be irreversible. The resulting page can no more be fragmented back into multiple sections at runtime.
In the case of multiple output document layout, the best choice is to let the pagination being handled at export time, each exporter providing its own handling mode. In order to accomplish this, one have to let the isIgnorePagination with its default value ie false. At fill time the document will be generated as multiple pages document.
Then, at export time, the exporter could decide whether to print out the document as multipage, or to concatenate all pages into a single one, by suppressing all empty space between pages. Handling Page Breaks with HTML Exporter When a multipage document gets exported into HTML format there are three possibilities to configure its layout: The document will be printed out page by page; only a single document page can be visualized at a time; one can navigate between pages using a navigation bar script.
All document pages will be printed out in a sequence where page breaks appear as noticeable amount of empty space on the vertical axis. Sometimes this is not a very user-friendly webpage and removing the extra blank space between pages is required.
In such a case a lot of help comes from the net. If this property is truethen all empty rows in the generated HTML table will be collapsed, leading to a completely flow-oriented layout. By default, the exporter preserves all the whitespace for pixel-perfect page layouts. All document pages will be printed out in a sequence where page breaks appear as a custom HTML separator.
One can replace the default blank space between pages with a customized separator element a horizontal line, for example.
All of them generate Excel-compatible documents organized as workbooks which store inside one or more separated sheets.
