However, I believe this may stop if this was drawn on listview permanently instead of being its own event being drawn every time.What I have tried:I tried using a creategraphicshere is the code I tried:With CreateGraphics() .DrawLines(New Pen(SystemColors.ButtonShadow), New Point() {New Point(ListView1.Bounds.Left, ListView1.Bounds.Top - 1), New Point(ListView1.Bounds.Left + ListView1.Bounds.Width, ListView1.Bounds.Top - 1), New Point(ListView1.Bounds.Left + ListView1.Bounds.Width, ListView1.Bounds.Top + ListView1.Bounds.Height), New Point(ListView1.Bounds.Left, ListView1.Bounds.Top + ListView1.Bounds.Height)}) End With 但它不起作用but it didn't work推荐答案 Protected Overloads Overrides ReadOnly Property CreateParams() As CreateParams 'stop flicker code part 1 of 2 Get Dim cp As CreateParams = MyBase.CreateParams cp.ExStyle = cp.ExStyle Or 33554432 Return cp End Get End Property Private Sub PreVentFlicker() 'stop flicker code part 2 of 2 With Me .SetStyle(ControlStyles.OptimizedDoubleBuffer, True) .SetStyle(ControlStyles.UserPaint, True) .SetStyle(ControlStyles.AllPaintingInWmPaint, True) .UpdateStyles() End With End Sub b $ b http://www.dreamincode.net/forums/topic/294248-flicker-problem-on-form-loading/ http://www.dreamincode.net/forums/topic/294248-flicker-problem-on-form-loading/ 这篇关于如何从formload中绘制listview列和行？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
