 Key Features:
 - Multi-page automatic content flow using pagination
 - Support for rich text formatting: headers, bullets, and tables
 - Insert images, tables, and charts seamlessly
 - Add interactive elements: bookmarks, hyperlinks, and attachments
 - Control layout: margins, page breaks, and dynamic footers
-
 Usage Example:
 This project demonstrates how to paginate multiple paragraphs of text describing PDF functionality. When the content exceeds a single page, Syncfusion’s PdfTextElement automatically creates new pages and triggers the PageAdded event. This allows you to attach custom footers, such as page numbers or custom codes, to each page for improved navigation and professional document appearance.
-
 Adding dynamic footers is useful for:
 - Section labeling in large documents
 - Including secure or traceable codes for each page
 - Ensuring readers always know their page context
-
 Other advanced scenarios:
 - Creating Table of Contents with page navigation
 - Inserting named destinations for quick jumps
 - Using graphics and interactive elements within the same document
-
 Experiment by updating this program to add headers, watermarks, or section-based page numbers based on your specific requirements.
