SelectPdf for .NET - Conversion Delay with Html to Pdf Converter

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

For pages that use javascripts heavily, the conversion can be delayed a number of seconds using converter.Options.MinPageLoadTime property to allow the content to be fully rendered.

In a similar way, if a page takes too much time to load, the converter can specify the amount of time in seconds when the page load will timeout using the property converter.Options.MaxPageLoadTime.

Delay conversion:
