java - iText tables - how to keep multi row cells on one page? -


i'm creating table in itext lists events date. if there mutliple events date, set rowspan property of date-cell number of events. i'm using row each event, since want display additional info event , want keep aligned. basicly table can this:

 date   | event     | details --------+-----------+---------------  date 1 | event 1   | details 1 --------+-----------+---------------  date 2 | event 2 1 | more          |           | details 2 1         +-----------+---------------         | event 2 2 | details 2 2 --------+-----------+---------------

the cell containing date 2 has rowspan of 2.

i add table using columntext.go() in loop.

if write table document , there enough space left event 2 1, event 2 2 goes new page. how can force new page before adding date 2?

using pdfptable.setsplitlate(true) doesn't seem affect multi row cells. neither setting fixed height of date 2 cell combined heights of 2 rows.

  • one solution use nested tables column 2 , 3 (and treat column 2 , 3 1 column)

  • another solution, doesn't work correctly in version of itext i'm using use pdfptable.writeselectedrows() , write (combined) rows fit on page. problem is, way row span ignored , date cells tey span 1 row.

are there other ways?

you create table each row , use pdfptable.setkeeptogether(true) works in itext 2.1.7, though wouldn't recommend staying version. here example, outputfile file type variable pdf file being created.

document document = new document(new rectangle(620, 150)); pdfwriter.getinstance(document, new fileoutputstream(outputfile));  document.open();  pdfptable headerrow = new pdfptable(3); headerrow.setkeeptogether(true); headerrow.addcell("date"); headerrow.addcell("event"); headerrow.addcell("details");  pdfptable firstrow = new pdfptable(3); firstrow.setkeeptogether(true); firstrow.addcell("date 1"); firstrow.addcell("event 2 1"); firstrow.addcell("more\ndetails 2 1");  pdfptable secondrow = new pdfptable(3); secondrow.setkeeptogether(true); pdfpcell cell = new pdfpcell(new phrase("date 2")); cell.setrowspan(2); secondrow.addcell(cell); secondrow.addcell("event 2 1"); secondrow.addcell("more\ndetails 2 1"); secondrow.addcell("event 2 2"); secondrow.addcell("details 2 2");  document.add(headerrow); document.add(firstrow); document.add(secondrow);  document.close();

honestly though, think nested table better idea.

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
