Is there a way where we can Sync scroll Label, TextBox or RichTextBox with ListBox ScrollBar?

ScrollBar should be visible only for ListBox and (Label, TextBox or RichTextBox should not have any scollbar)

I've mentioned Label, TextBox or RichTextBox, anyone could work for me, whichever is compatible to sync scroll with ListBox.

What I have tried:

I tried 2 RichTextBox sync but thats not what I'm looking for, though, I've also tried 2 ListBox Scroll and I've Hide 1 ScrollBar Scroller but that is slow and not scrolling together, there's a delay of some milliseconds.

I got this working for a ListBox and a RichTextBox but only one way... Meaning that scrolling the RTB will scroll the LB but not the opposite
Here is the code... Put it in the VScroll function of the RTB

VB

Dim lineNumber As Integer = 0

lineNumber is a global variable...

VB

Dim firstVisibleChar As Integer = RichTextBox1.GetCharIndexFromPosition(New Point(0, 0))
lineNumber = RichTextBox1.GetLineFromCharIndex(firstVisibleChar)
ListBox1.TopIndex = lineNumber

I know we can simplify this code more, but I've made it a bit longer so that anyone can easily understand it...
