[2008] Working with custom mouse events

Hi guys,

I came across an issue I had not expected when I was writing up my custom panel control. Apparently when the mouse enters a panels children it triggers a mouse leave event on the panel. This means my code does not work. I can update the custom children because the panels children need not only be custom controls. I'm kind of stumped. I though about looking to see if the mouse is in the panels border but im unsure of how to do this and imagine that the mouse would be considered out of bounds when it enters the children. Any suggestions?

VB Code:

Public Class RollOverPanel
    Inherits System.Windows.Forms.Panel
 
    ''' <summary>
    ''' Loops through each RollOver control and calls the triggeroff() method of said 
    ''' controls. TriggerOn() changes the controls base color to its "hot" color.
    ''' </summary>
    ''' <remarks>Currently only the RollOverLabel control is tested</remarks>
    Private Sub ActivateHotControls()
        For Each Control In Me.Controls
            If TypeOf Control Is RollOverLabel Then
                Dim CurrentLabel As RollOverLabel
                CurrentLabel = CType(Control, RollOverLabel)
                CurrentLabel.TriggerOn()
            End If
        Next
    End Sub
 
    ''' <summary>
    ''' Loops through each RollOver Control and calls the triggeroff() method of said 
    ''' controls. TriggerOff() reverts from the controls "hot" color to its base color. 
    ''' </summary>
    ''' <remarks>Currently only the RollOverLabel control is tested</remarks>
    Private Sub DeactivateHotControls()
        For Each Control In Me.Controls
            If TypeOf Control Is RollOverLabel Then
                Dim CurrentLabel As RollOverLabel = CType(Control, RollOverLabel)
                CurrentLabel.TriggerOff()
            End If
        Next
 
    End Sub
 
    Protected Overrides Sub OnMouseEnter(ByVal e As System.EventArgs)
        MyBase.OnMouseEnter(e)
        ActivateHotControls()
    End Sub
 
    Protected Overrides Sub OnMouseLeave(ByVal e As System.EventArgs)
        MyBase.OnMouseLeave(e)
        'This is the offending line.
        DeactivateHotControls()
    End Sub
 
End Class

Bump for help.

Sorry post makes no sense, just very tired.

Ok, I think i may know in theory how to do this. As far as I can see on MSDN the panel.location returns the panels X and Y cordinates as a rectagle. If I create a new rectangle with these values plus the size of the panel control like so

Dim MyRec as Rectangle
MyRec.X = Panel.Location.X
MyRec.Y = Panel.Location.Y
MyRec.Size = Panel.Size

I should get a Rectangle that is the same size as the panel at the same location from what I read. The issue seems to be that the mouse cordinates map to the screen rather than the client form. Where as i imagine that the cordinates of my rectangle map to the client form because thats what the panel maps to. This means that these two wont match. The other side of it is that my development PC has two monitors and this could be squewing my values even further.

Any Insight to this guys?
Thanks
