Hello Pablo,

Thank you for contacting Infragistics Community!

The igxPreventDocumentScroll directive has been created in order to resolve the following issue opened in the IgniteUI for Angular Samples Repository. Its purpose is to prevent the document scrolling when, for example, the bottom of the grid is reached while scrolling over it and the user continues to scroll down. Please take a look at the following sample I have prepared for you.

P.S. If running the sample in Google Chrome you won’t notice any difference because of its default behavior. That’s why I suggest opening the attached sample in Mozilla Firefox.

Please let me know if you need any further information.

Thank you for using Infragistics Components.
