How to use WindowStatus in HTML converter For .NET WebForms PDF?
We can manually wait HtmlConverter up to the document loading using WindowStatus property in HTML converter. We can use windows status instead of addition delay. In additional delay, we do not know the exact time that need for execution of JavaScript. By windows status you can avoid this problem.
Both window status should be same, else converter never stops the conversion
