Hi Vignesh, 

Thank you for contacting Syncfusion support. 

To add the dots between the content and page number, we have to measure the size of the content using measure string function. Using the content starting location and content size, we need to draw the dots manually in a for loop until reaching the page number location.  

Please refer below links for more information, 

https://help.syncfusion.com/cr/file-formats/Syncfusion.Pdf.Graphics.PdfFont.html#Syncfusion_Pdf_Graphics_PdfFont_MeasureString_System_String_  

Please refer the below simple sample code, 

string content = "TOC content"; 

float x = 10; 

float y = 40; 

PdfDocument document = new PdfDocument(); 

document.PageSettings.Margins.All = 0; 

 

int pageNumber = 1; 

PdfPage page = document.Pages.Add(); 

 

PdfStandardFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 11); 

 

//Draw content 

page.Graphics.DrawString(content, font, PdfBrushes.Black, x, y); 

 

float dotStartPosition = font.MeasureString(content).Width; 

float dotEndPostion = font.MeasureString(pageNumber.ToString()).Width; 

 

for (float i = dotStartPosition; (x + i) < (page.GetClientSize().Width - 15 - dotEndPostion); i = i + 2) 

{ 

     //Adding dots 

     page.Graphics.DrawString(".", font, PdfBrushes.Black, (x + i) , y); 

} 

 

//Draw page number 

page.Graphics.DrawString(pageNumber.ToString(), font, PdfBrushes.Black, page.GetClientSize().Width - 15, y); 

 

MemoryStream stream = new MemoryStream(); 

 

document.Save(stream); 

document.Close(); 

 

File.WriteAllBytes("Sample.pdf", stream.ToArray());
