SelectPdf for .NET - Exclude Elements from Conversion with Html to Pdf Converter - C# / ASP.NET MVC Sample

This sample shows how the html to pdf converter can be used to convert a web page excluding certain elements from the conversion using SelectPdf Pdf Library for .NET.

The elements from the page that will be excluded from the converted pdf document are defined using CSS selectors. For example, the selector for all the H1 elements is "H1", the selector for all the elements with the CSS class name 'myclass' is "*.myclass" and the selector for the elements with the id 'myid' is "*#myid".
