how to make tooltip for a TreeviewAdv nodes

[mred]

Hello,

I want to show tooltips for nodes of a TreeviewAdv. I don't know how to write it?
I wanted to write in below sub but the sub itself has also problem. for example this part is red and i don't know how to solve it?

Private Sub TreeViewAdvSII_MouseHover(sender As Object, e As ) Handles TreeViewAdvSII.MouseHover
   
End Sub

From which component pack does this come from? Syncfusion has a TreeViewAdv which has a .HelpText property https://support.syncfusion.com/kb/ar...iewadv-control
