You're only adding "Page X" here, you forgot to add the template.

Why do you say:

This method should be in the event class:

NO NEED TO ADD "Page X of Y" here!!!

This is your actual class:
event.createNewTemplate(writer);
> document.add(employeesTable);
event.fillOutTemplate(writer);

Reading your code, that's exactly the behavior I'd expect.
> Please let me know, why template is not filled out at end of every page?
Because you didn't grasp the concept I was trying to explain:
createNewTemplate and fillOutTemplate should be methods that are part of
the event. m_Template needs to be used on the onEndPage method!
> Do i need to use, onChapter & onChapterEnd to fill the template?
Please stop talking about onChapter and onChapterEnd!

Re: [iText-questions] Page Number problem when table ends at the complete end of the page
I had implemented your solution:
Sample Code in event listener:
onEndPage(){
final int page = writer.getPageNumber();
String text = "Page " + page;
m_BaseFont = BaseFont.createFont(BaseFont.
HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
m_Cb = writer.getDirectContent();
if(m_Cb!=null){
m_Cb.beginText();
m_Cb.setFontAndSize(m_BaseFont, 8);
m_Cb.showTextAligned(PdfContentByte.
ALIGN_RIGHT,text,410,20,0);
m_Cb.endText();
}
}
Sample code in program:
createNewTemplate(PdfWriter arg0){
try {
m_BaseFont = BaseFont.createFont(BaseFont.
HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
m_Cb = arg0.getDirectContent();
m_Template = m_Cb.createTemplate(85,87);
final int page = arg0.getPageNumber();
String text = "Page " + page;
if(m_Cb!=null){
m_Cb.beginText();
m_Cb.setFontAndSize(m_BaseFont, 8);
m_Cb.showTextAligned(PdfContentByte.
ALIGN_RIGHT,text,410,20,0);
m_Cb.endText();
m_Cb.addTemplate(m_Template, 352.3f, 20);
}
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
fillOutTemplate(PdfWriter arg0) {
System.out.println("fillOutTemplate:"
+arg0.getPageNumber());
m_Template.beginText();
m_Template.setFontAndSize(m_BaseFont, 8);
String text = "of " + (arg0.getPageNumber() );
m_Template.showTextAligned(PdfContentByte.ALIGN_LEFT,
text, 65, 0, 0);
m_Template.endText();
}
this.createNewTemplate(writer);
document.add(employeesTable);
this.fillOutTemplate(writer);
When this code is executed, it displays page 1 of X in first page, but
page 2 , page 3 in rest of the pages.
When a new table starts it displays againg page 1 of Y, followed by page 2
and page 3.
Please let me know, why template is not filled out at end of every page?
Do i need to use, onChapter & onChapterEnd to fill the template?
Thanks,
Suresh

Don't use Chapters, but use document.newPage() every time
you've added a table.
Remove:

Replace them with normal methods, such as:
public void createNewTemplate()
and
public void fillOutTemplate()
(Or whichever name you think describes best what the method does.)
Call these methods before and after document.newPage().

[iText-questions] Page Number problem when table ends at the complete end of the page
I am trying to display mutiple tables in a single PDF and display page X of Y
at the end of each page.
X, Y should reset for every new table(Basically every new table should start
with a new page.)
Each table can vary and span accross multiple pages.I am ChapterAutoNumber,
PdfPTable & custome event handler.
I don't have problem while tables end in the middle of page(1 page of
multiple pages).
The problem comes when the table size matches page size.
If a table size is approximately equal to page size.
Then onStartPage of new page(second) is invoked before onChapterEnds and
onEndPage are invoked.
So it displays page 1 of 2, when it has only one page.
For tables ending in the middle of page, if it has 3 pages, page numbers are
displayed correctly as
1 of 3 , 2 of 3 , 3 of 3. But when table size ends at the end of page, if
there is 1 page, it display 1 of 2.
Code looks like below:
public void onChapter(PdfWriter arg0, Document arg1, float arg2,
Paragraph arg3) {
try {
m_BaseFont = BaseFont.createFont(BaseFont.HELVETICA,
BaseFont.CP1252,
BaseFont.NOT_EMBEDDED);
m_Cb = arg0.getDirectContent();
m_Template = m_Cb.createTemplate(85,140);
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
public void onChapterEnd(PdfWriter arg0, Document arg1, float arg2) {
m_Template.beginText();
m_Template.setFontAndSize(m_BaseFont, 8);
String text = "of " + (arg0.getPageNumber() );
m_Template.showTextAligned(PdfContentByte.ALIGN_LEFT, text, 65,
0, 0);
m_Template.endText();
}
public void onEndPage(PdfWriter writer, Document arg1) {
final int page = writer.getPageNumber();
String text = "Page " + page;
if(m_Cb!=null){
m_Cb.beginText();
m_Cb.setFontAndSize(m_BaseFont, 8);
m_Cb.showTextAligned(PdfContentByte.ALIGN_RIGHT,text,410,20,0);
m_Cb.endText();
m_Cb.addTemplate(m_Template, 352.3f, 20);
}
}
Please help.
