Reduce Flicker of .NET FlowLayoutPanel

Question

I'm clearing and adding multiple LinkLabel's to FlowLayoutPanel, every couple of seconds. It works fine, but flicker is quite noticeable. Is there any way to reduce it? I tried to set Form.DoubleBuffering, it didn't help.

Answer 1

Managed by creating a custom control derived from FlowLayoutPanel and setting its styles as shown below:

Public Class CustomFlowLayoutPanel Inherits FlowLayoutPanel

Public Sub New()
    MyBase.New()

    SetStyle(ControlStyles.UserPaint, True)
    SetStyle(ControlStyles.AllPaintingInWmPaint, True)
    SetStyle(ControlStyles.DoubleBuffer, True)

End Sub

End Class

Answer 2

Try calling SuspendLayout() for the panel before adding controls to it and then call ResumeLayout() on the Panel. You may lose that flicker a bit.
