Hi Vladimir, 
 
Thank you for contacting Syncfusion support. 
 
We can get the last page of the PDF document by using PdfLoadedPageCollection.PageCount property, we have created a sample for inserting PdfTextElement in bottom of the last page for your reference, please refer the below code snippet and sample for more details. 




            //Load the existing PDF document  
            PdfLoadedDocument ldoc = new PdfLoadedDocument("../../Barcode.pdf"); 
 
            //Get the PDF document page count 
            int pageCount = ldoc.Pages.Count; 
 
            //Get the last page 
            PdfLoadedPage lastPage = ldoc.Pages [pageCount-1] as PdfLoadedPage ; 
 
            //Create a new PDF text element 
            PdfTextElement lastPageElement = new PdfTextElement("This is the last page", new PdfStandardFont(PdfFontFamily.Helvetica, 15, PdfFontStyle.Bold), PdfBrushes.Red); 
 
            //Draw the text element to the last page of the document 
            lastPageElement.Draw(lastPage.Graphics, new System.Drawing.PointF(0, lastPage.Size.Height - 20)); 
 
            //Save the document  
            ldoc.Save("output.pdf"); 
 
            //Close the document 
            ldoc.Close(true);
