Scroll panel auto hide inside components - vb.net

Question

My code works, but The problem is I put a listbox in it. I want to make sure that even when the user hovers over the list box, the pane will close.
I am having 2 issues:
MAIN ISSUE: The panel's timers are not working because the listbox component is sort of blocking it out. I am unsure how to counteract this.
I want to hide or collapse the listbox for visual appeal.
Here is my code:
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Panel1.Dock = DockStyle.Left
End Sub
Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
If Panel1.Width < 150 Then
Panel1.Width = Panel1.Width + 100
ElseIf Panel1.Width = 150 Then
Timer1.Enabled = False
End If
End Sub
Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick
If Panel1.Width >= 100 Then
Panel1.Width = Panel1.Width - 50
If Panel1.Width < 100 And Panel1.Width > 25 Then
Panel1.Width = Panel1.Width - 15
End If
ElseIf Panel1.Width <= 25 Then
Timer2.Enabled = False
End If
End Sub
Private Sub Panel1_MouseEnter(sender As Object, e As EventArgs) Handles Panel1.MouseEnter
Timer1.Enabled = True
Timer2.Enabled = False
End Sub
Private Sub Panel1_MouseLeave(sender As Object, e As EventArgs) Handles Panel1.MouseLeave
Timer1.Enabled = False
Timer2.Enabled = True
End Sub
End Class

Answer 1

The ListBox will cause the panel's MouseEnter and MouseLeave events to fire.
So comment out those events:
'Private Sub Panel1_MouseEnter(sender As Object, e As EventArgs) Handles Panel1.MouseEnter
' Timer1.Enabled = True
' Timer2.Enabled = False
'End Sub
'Private Sub Panel1_MouseLeave(sender As Object, e As EventArgs) Handles Panel1.MouseLeave
' Timer1.Enabled = False
' Timer2.Enabled = True
'End Sub
Then try adding a third timer to track the mouse over the panel:
Private Sub Timer3_Tick(sender As Object, e As EventArgs) Handles Timer3.Tick
If Panel1.ClientRectangle.Contains(Panel1.PointToClient(MousePosition)) Then
If Not Timer1.Enabled AndAlso Panel1.Width < 150 Then
Timer1.Enabled = True
Timer2.Enabled = False
End If
Else
If Not Timer2.Enabled AndAlso Panel1.Width > 25 Then
Timer1.Enabled = False
Timer2.Enabled = True
End If
End If
End Sub
