MouseEnter Event problem for panel with 'Dock' property

Question

Hi all,

I am craeting a windows application with vb.net 2005. I am using Panel with 'Dock' Property is 'Left'. My panel includes Buttons also.In the application in MouseEnter event of the Panel will set the Panel.Width=200. And in MouseLeave Event,Panel.Width=10. But the problem is While MouseEnter on the buttons inside the panel,the Panel_MouseLeave Event is triggering and Panel Width is set to 10. How to rectify this problem

Please help me.

Best regards,

Fuad

Try this Public Class Form1 Dim pt As Point Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load Panel1.Width = 10 End Sub Private Sub Panel1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles Panel1.MouseEnter Panel1.Width = 200 End Sub Private Sub Panel1_MouseLeave(sender As System.Object, e As System.EventArgs) Handles Panel1.MouseLeave If pt.X > Panel1.Width - 10 Then Panel1.Width = 10 End If If pt.Y Panel1.Width = 10 ElseIf pt.Y > (Panel1.Height - 10) Then Panel1.Width = 10 End If End Sub Private Sub Panel1_MouseMove(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove pt = e.Location End Sub End Class

The only time for me that it did not trigger is when i moved the mouse left. I did not provide code for that situation Another way is Private Sub Form1_MouseMove(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseMove Panel1.Width = 10 End Sub
