Fade a Panel [RESOLVED]

[john tindell]

Is it possible to change the opacity on a Panel control. I have search but all i could find was about window forms.

Thanks

I have a quivk VB sample here... Havent got C# at home :) Shouldn't be hard to translate.

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'timer event handler
Static aa As Integer

Panel1.BackColor = Color.FromArgb(aa, 255, 0, 0)
aa += 10 'amount of opacity change for each timer tick

If aa > 255 Then Timer1.Enabled = False 'finished fade-in

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Timer1.Interval = 100 '10 times a second
Timer1.Enabled = True 'go!

End Sub

That should get you started. It simply uses a timer to increase the Alpha component of the panel's backcolor. Its a bit flickery but you could always use a backbuffer to solve that problem, if you can be bothered :D
