SelectPdf for .NET 10 - Control Page Breaks with Html to Pdf Converter - C# / .NET 10 Sample

This sample shows how to use SelectPdf html to pdf converter to convert a raw html code to pdf and also how to control the page breaks from the html code.

To insert a page break in pdf, the html code must have an element with the style page-break-before: always or page-break-after: always. Before or after that specific element, a page break will be inserted into the generated pdf document. The element can be anything (image, table, table row, div, text, etc).

To instruct a certain section from the content to remain on the same page in the generated pdf document, an element with the style page-break-inside: avoid must be used.
