iTextSharp - finding end of page - itext

Is there any way to find the current page is going to end in iTextSharp. For example,
say there are some 10 records which needs two pages to be written down at the end of the first page i wish to add '(contd on nex page'). IS there a way to do this. Will finding the end of page be an answer for this or is there a way to find the line number on which writing is done, so that i can make a calculation to decide whether to add a message of my choice and proceed to the next page.
any advise is much appreciated :)
Thanks a zillion

Usually, this is done by defining a footer for the table. When the table breaks automatically, iText will show that footer. Of course: you don't want this footer to show up on the last page (after the final row of the table). That's why there's also a method to skip the last row.
This example shows you how to create a table with headers and footers. This is the link to SkipLastFooter.
Note that saying that "finding the line number" would solve your problem is wrong for two reasons:
There is no such thing as a line number in a PDF file. You have a MediaBox and you draw content on the canvas defined by the MediaBox using coordinates.
There's a way to get the current Y-position on a page after adding an object to a document. You can get the Y-position before adding a table and after adding a table, but not while you're still creating the table.
An alternative solution to the one I suggested above, woult be to use table events.

If you really need to find the end of the page, and are not using a table with a footer row that will be printed at the end of each page, you can use the PdfWriter object as follows:
var remainingPageSpace = pdfWriter.GetVerticalPosition(false) - pdfDocument.BottomMargin;
This will give you the remaining space on the page, from which you can determine what you want to do next.
If you are using tabular data however, it is much preferred to use a PdfPTable and take advantage of the footer row feature.

How can I use Footnotes with Oracle BI Publisher

I am putting a footnote in an .rtf template, and before generating a report it seems ok,
but when I load an XML sample and preview the document (.pdf or .doc etc.)
the footnote content goes right into the body of my report (example is in the picture).
I've tried using text boxes, but it doesn't help.
I've also tried just making a paragraph look as a footnote, but since I have a lot of
tags in my template, the footnote-looking text doesn't stay at the
bottom of the page.
and I can't use footers/headers because I need only one footnote at one page.
Try to draw a borderless table with one column and two rows where the first row has fixed hight (exactly) of the size of body, and the second row fixed hight of the size you want to reserve for the footer. Then you place your xml data in those two rows of the table the same way as you put it on the page. I use that for different forms when the position of the data is fixed. There are also other table/row/column properties that you might want to use.

Table remove column header if no columns on page

I have a JasperReports's report with some data and a table. The problem is when the table splits on 2 pages sometimes on the first one is only the header of the table. I want it to split (can't use Prevent), but only if it is at least one line of detail (if not, all should move to the next page).
Bad Here:
Good Here:
On the first example (the bad one) first header should not be printed.
Ideas?
Put your table header into a group header, then follow the advice on the question:

SSRS unusual Pagebreak in a long text

i am creating a report for SQL Server 2008.
i have a table with some rows. One of the row has a long text which will be displayed. If the text has a certain length, the whole row will be displayed on the second page and the half of the first page is empty.
If the text is a bit shorter, the text will be displayed correctly on the first page.
If the text is a bit longer, the text will also be displayed correctly (the first part of the text on the first page, the second part on the second page).
I cant find any settings for this problem.
Does anyone have a solution?
Thanks

You could look at the Keep together on one page if possible setting at the Tablix level.
You can also look at the KeepTogether property at the row level and at other levels, e.g. Group.
Another option is to insert any objects to be kept together in a parent Rectangle object; this will always keep items together where possible.

iTextSharp and moving some data to next page

I am creating an invoice using the iTextSharp. That displays nicely but sometime, when invoice items are larger in qty, the summary portion (which displays subtotal, tax, discounts, grand total etc) is splitted. Some displayes in current page and some moves to next page. I was thinking to move entire summary portion into next page, if current height left is not enough for that.
However, to do that, I need to know that how much page height is left (after my current page content rendering). I wonder if someone know how to calculate current left height of the page? OR if there is a property in the pdfPTable which may force the table to print itself as a whole and dont let it split across multiple pages! I guess if second option is available, it will be easy.
In summary, I need to know if it is possible to calculate remaining page height, and also if that is possible to force a table to NOT split across multiple pages.
thank you.

You can set SplitLate to false to avoid auto page break in a cell data exceeds limit.
......
table.addCell(cellData);
table.SplitLate = false;
......
I suggest you use a nested table for your summary section. I don't believe iText will split a given cell on a page boundary, so everything in that cell (even if its a nested table with cells of its own) will stay on the same page.
Use the table's cell's row span so it takes up an entire row on its own.
I'm not certain, but I'd wager a beer on it.
What object are you using to add your data to the PDF? MultiColumnText, Paragraph, Phrase?
You should be able to use Document.PageSize.Height property to return the height of the Page.
Then use PDFPTable.Height to return the height of your table.
So just use the logic Document.PageSize.Height - table.Height, and you'll have the remaining y-axis space available.
The PDFPTable object has properties named SplitLate and SplitRows. I believe you can use these properties to try and keep the table on one page.

Crystal Reports: Cross-Tab Column Arrangements

I am looking for a way out in cross tab, so that if the columns exceed in cross tab, they shouldnt go on next page..rather a new cross-tab should repeat after the first one.
For example, two columns are displayed in a cross tab :
Now if a new column is added, and assuming that it could not be accomodated within the given page width limit, it will go to a page next to it in CR by default.
But in my report it is required to be shown below the first cross tab (and not on next page), which will look as follows:
Please do suggest me if there's a way out :)
Thanks in advance
Your question is perfectly reasonable, but I'm pretty sure that in CR-XI, there is no automatic way to do this. I recommend skipping the cross-tab designer completely and just making your own:
Make a new CR using a placeholder table that has exactly 1 record.
In this CR, suppress everything but the details section. Add a new details section so you will have Da and Db.
In Da, add a subreport. Use your real datasource and add Column1 and Column2.
In Db, add a subreport. Use your real datasource and add Column3 and Column4.
I don't have time to test this, but I think it will display all the columns as you requested.
(Instead of step 1, you can probably use a placegrouper group in your report that only has 1 group. Then, when you add the subreports, make sure to not add any links to the main report.)
Edit
A dynamic number of columns makes this request much more difficult to do in Crystal.
Maybe you could autogenerate the entire report from a script. I couldn't help you with that, but I'm sure someone else on StackOverflow will.
You can use MS Excel to achieve something similar. Use MS Access or something similar to set up a crosstab of your data. Open a new Excel workbook and import your crosstabbed datasource using Data->Import External Data->Import Data (this imports the entire table, regardless of number of rows). In Page Setup, change settings to Fit to (blank) pages wide by 1 pages tall. You can format the data however you like and the format will be retained. This Excel method will squeeze all your columns into a 1-page wide area. It's not quite what you're asking for, but it will work.
The number of columns may be dynamic, but do you know what the field names could be? For example, your columns include 0-50 US States, then you know what the column names will be, just not which ones or how many. If this is your situation, then use my first suggestion (check off the suppress if blank options to hide unneeded subreports). It won't be pretty (alot of white space), but it can get the job done.
A possible solution can be a multi column report. But it can be difficult to make the row labels and values in the same line.
If you can create an additional row grouping then you have the solution that you want. For example if your columns have number like in your sample. Then you can add a formula like:
columnId \ 2
