I am using dbAutoTrack for generate PDF in that I have to add Table but I get the Exception like object references is not set to an instance of object
Below is my code
Table t=new Table();
Row row=new Row(t);
row.Cells.Add("ABC");
t.Rows.Add(row);
_pdfGraphics.DrawTable(100,200, t);
where _pdfGraphics is object of PDFGraphics.
Thanks in Advances
Most probably you have message like: "Not enough columns in this row to have a column span of 1." And you needed just to add them.
Workable sample:
//Initialize a new PDF Document
Document _document = new Document();
_document.Title = "Аpitron Sample";
_document.Author = "StanlyF";
_document.Creator = "АPItron LTD.";
Page page = null;
PDFGraphics graphics = null;
Table _table = new Table();
_table.Columns.Add(30);
Row row = new Row(_table);
row.Height = 25;
row.Cells.Add("ABC");
_table.Rows.Add(row);
while (_table != null)
{
//Initialize new page with default PageSize A4
page = new Page(PageSize.A4);
//Add page to document
_document.Pages.Add(page);
//Get the PDFGraphics object for drawing to the page.
graphics = page.Graphics;
_table = graphics.DrawTable(100,200, _table);
}
using(FileStream _fs = new FileStream("Table_Sample.pdf", System.IO.FileMode.Create, System.IO.FileAccess.Write))
{
//Generate PDF to the stream
_document.Generate(_fs);
Process.Start("Table_Sample.pdf");
}
The accepted answer didn't work for me and I was still getting null reference exceptions. It turns out that the rows need to be added with a TableStyle otherwise the cells, for whatever reason, won't be generated:
StandardFonts standardfont = StandardFonts.Helvetica;
PDFFont fontSmall_reg = new PDFFont(standardfont, FontStyle.Regular);
TableStyle ts = new TableStyle(fontSmall_reg, 12, nullBorder);
Table data = new Table(ts);
data.Columns.Add(100);
data.Columns.Add(100);
Row r = new Row(data, ts);
r.Height = 25;
r.Cells.Add("Row 1 Col1");
data.add(r)
r.Cells.Add("Row 1 Col2");

I'm traying to test this method that checks for specific tag footer to show.
here is the function:
public void CheckForOrderOfFooterTags(PdfDocument pdfDoc, out TagTreePointer autoP, out TagTreePointer posBackup, out TagTreeInfo p)
{
// the following logic takes care of changing the order of the footer tags
// so that footers appear in the proper order in the tag tree structure
autoP =pdfDoc.GetTagStructureContext().GetAutoTaggingPointer();
posBackup =new TagTreePointer(autoP);
PagesTag.TryGetValue(PageNumber, out p);
if (p?.TagTreePointer != null)
{
// Make sure that content that will be tagged is placed in tag structure specifically where we need it.
int indexInParentKidsList = p.TagTreePointer.GetIndexInParentKidsList();
autoP.MoveToPointer(p.TagTreePointer).MoveToParent();
// setting new index only works on taggable items
if (p.Tagged)
{
autoP.SetNextNewKidIndex(indexInParentKidsList + 1);
}
}
}
and this is the test:
public void Check_For_Specific_Tag_Footer_To_Show_Successfully_Called()
{
var ir = new TestIllustrationReport().Report;
var reportProperties = new TestDocument().ReportProperties;
var sec = new FooterSection(new ProductContent(ir));
sec.Build();
Dictionary<int, TagTreeInfo> dict = new Dictionary<int, TagTreeInfo>();
reportProperties.FooterTag=dict;
FooterEventHandler footerEvent = new FooterEventHandler(sec, reportProperties);
// Must have write permissions to the path folder
var path = System.IO.Path.GetTempPath();
var fileName = System.IO.Path.ChangeExtension("Test", ".pdf");
var com = System.IO.Path.Combine(path, fileName);
// pdf
PdfWriter writer = new PdfWriter(com);
PdfDocument pdf = new PdfDocument(writer);
Event headerEvent= new PdfDocumentEvent("pdf", pdf);
PdfDocumentEvent docEvent = (PdfDocumentEvent)headerEvent;
iText.Layout.Document document = new iText.Layout.Document(pdf);
pdf.GetCatalog().SetLang(new PdfString("en-US"));
// Header and Paragraph
Paragraph header = new Paragraph(TestData.Header)
.SetTextAlignment(TextAlignment.CENTER)
.SetFontSize(20);
document.Add(header);
pdf.SetTagged();
pdf.GetCatalog().SetViewerPreferences(new PdfViewerPreferences().SetDisplayDocTitle(true));
PdfDocumentInfo info = pdf.GetDocumentInfo();
info.SetTitle("Testing tags");
Paragraph p = new Paragraph();
p.Add("The quick brown ");
PdfPage page = docEvent.GetPage();
// Rectangle and canvas
Rectangle rectangle = new Rectangle(
pdf.GetDefaultPageSize().GetX() + document.GetLeftMargin(),
pdf.GetDefaultPageSize().GetTop() - 80,
page.GetPageSize().GetWidth() - document.GetLeftMargin() - document.GetRightMargin(),
50);
Div canvas = new Div().SetFixedPosition(pdf.GetPageNumber(page), rectangle.GetLeft(), rectangle.GetBottom(), rectangle.GetWidth());
Paragraph pFooter = new Paragraph(TestData.Paragraph);
pFooter.GetAccessibilityProperties().SetRole("H");
canvas.Add(pFooter);
document.Add(canvas);
// Don't close document itself! It would close the PdfDocument!
document.GetRenderer().Close();
var pPointer = new TagTreePointer(pdf);
var pInfo = new TagTreeInfo { Tagged = true };
// Act
footerEvent.CheckForOrderOfFooterTags(pdf, out pPointer, out pPointer, out pInfo);
document.Close();
// Assert
Assert.NotNull(pdf);
}
For this test, I needed to create the pdf, set and build the footer section. I added the header to the pdf and the "footer test", I also set the document to be tagged.
I don't know why I always get the page is null if I'm adding a header and a paragraph to it.
I'm generating a docx file using NPOI 2.5.2 and I stuck with headers/footers for first page.
I'd like to have a first page custom footer and start numbering pages from the second one.
Here is my code for the first page footer:
// First page
doc.Document.body.sectPr = new CT_SectPr();
var footer = new CT_Ftr();
var footerParagraph = footer.AddNewP();
footerParagraph.AddNewR().AddNewT().Value = $"FIRST PAGE CUSTOM FOOTER";
var footerPar = new XWPFParagraph(footerParagraph, doc);
var parsFooter = new XWPFParagraph[1];
parsFooter[0] = footerPar;
var headerFooterPolicy = doc.GetHeaderFooterPolicy();
if (headerFooterPolicy == null)
headerFooterPolicy = doc.CreateHeaderFooterPolicy();
headerFooterPolicy.CreateFooter(XWPFHeaderFooterPolicy.FIRST, parsFooter);
Here is my code for the default footer with page numbering:
// Other pages
footerParagraph = footer.AddNewP();
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.begin;
footerParagraph.AddNewR().AddNewInstrText().Value = " PAGE ";
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.separate;
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.end;
footerPar = new XWPFParagraph(footerParagraph, doc);
parsFooter = new XWPFParagraph[1];
parsFooter[0] = footerPar;
headerFooterPolicy.CreateFooter(XWPFHeaderFooterPolicy.DEFAULT, parsFooter);
With the code above I could not see the first page custom footer but the page numbering in every page. What am I doing wrong?
I found this similar question but I could not find addNewTitlePg method in NPOI.
And is there any appropriate documentation with examples about NPOI?
Here is my code with the first footer working. (using NPOI 2.5.3)
var doc = new XWPFDocument();
using (var sw = File.Create("fileformat.docx"))
{
XWPFParagraph p1 = doc.CreateParagraph();
XWPFParagraph p2 = doc.CreateParagraph();
XWPFRun r1 = p1.CreateRun();
XWPFRun r2 = p2.CreateRun();
r1.SetText("The quick brown fox");
r1.AddBreak(BreakType.PAGE);
r2.SetText("Next page: The quick brown fox");
doc.Document.body.sectPr = new CT_SectPr();
var policy = doc.CreateHeaderFooterPolicy();
var ctSectPr = doc.Document.body.sectPr;
if (ctSectPr.titlePg == null)
{
ctSectPr.titlePg = new CT_OnOff() { val = true };
}
var firstFooter = policy.CreateFooter(ST_HdrFtr.first);
var paragraph = firstFooter.CreateParagraph();
var run = paragraph.CreateRun();
run.SetText("First page footer...");
var defaultFooter = policy.CreateFooter(ST_HdrFtr.#default);
paragraph = defaultFooter.CreateParagraph();
run = paragraph.CreateRun();
paragraph.Alignment = ParagraphAlignment.RIGHT;
paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.begin;
paragraph.GetCTP().AddNewR().AddNewInstrText().Value = " PAGE ";
paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.separate;
paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.end;
run = paragraph.CreateRun();
doc.Write(sw);
}
I am just using OpenXML for manipulating docx document. I have templates that has notation like
{{userFirstName}}
{{tableOfUsers}}
{{signatureImage}} etc
I need to replace those text with table, image etc. How to do that in Openxml ?
I'm using C# .Net core 3.1 with OpenXML 2.5

.Where(x => x.Text.Contains(tablePlaceholder))
.First();
if (tablePl != null)

//Insert the table after the paragraph.
var parent = tablePl.Parent.Parent.Parent;
parent.InsertAfter(table, tablePl.Parent.Parent);
tablePl.Text = tablePl.Text.Replace(tablePlaceholder, "");
wd.MainDocumentPart.Document.Save();
}
string docText = wd.MainDocumentPart.Document.Body.OuterXml;
Regex regexText = new Regex("{{name}}");
docText = regexText.Replace(docText, "Claire " + DateTime.Now.ToString());

You are looking for {{table}} in your code, but the notation in your template is {{tableOfUsers}}.
I have this code using openxml sdk which generates table in PPT report.

Links to previous questions:
create dynamic table in powerpoint using openXML with c# and ASP.net
unable to generate second table in PPT report using openxml
How to ignore/solve "Repair" message from Powerpoint report generated by OpenXML with ASP.net
Solved it.
So what I did was, I created a new ppt > inserted tables with required design manually in it and then saved it as ppt xml (you will see this option in save as).
Open that xml search for tablestyleid and use that value in the code.
I have written a method to insert a table in a word document using Open XML. The method accepts a generic list and a few parameters to control number of columns, column headings etc.
That all works fine.
However when populating the cells in the table I want to pull out the values for each row and place them in their corresponding columns. Given the names of the properties are going to change depending on the contents of the generic list, I am not sure how to accomplish this.
Anyone that can point me in the right direction it would be appreciated.

I resolved this issue by tackling the problem another way. Essentially rather than passing a List to the Insert Table Method. I decided to Pass a Multi-Dimensional Array with all the data need for the table including the table headings. This essentially meant that the Insert Table method would be more generic and any customization i.e. Generating Data, Specifying Column Headings etc would be done in the Method calling Insert Table.
