The problem appair when you don't put any value at design time and have a column hide.
In your examples, delete all nodes and then hide the 2° column. At this point you can't set vertical scroll

>Hi Maria,
Thank you for your interest in Syncfusion products.
I am afraid that I was not able to reproduce the issue you specified.
I could able to set vertical scroll for MultiColumnTreeViewAdv with VScroll property.
I have also attached an avi file with this.

Thanks,
