Question

I have a TableLayoutPanel where I do some Drag&Drop stuff with the controls inside the layout. Unfortunately the controls are flickering after the drop action. I tried DoubleBuffered=true on all controls and a lot of other things. I also tried this solution: How to fix the flickering in User controls. And actually it works pretty well with the mentioned CreateParams. But only until I resize the form. It seems that windows forgets the WS_EX_COMPOSIET flag after a resize. It appears only with the aero theme. Without aero it keeps the settings of the CreateParams after a resize.

当空气主题被打开时,有没有办法防止闪烁?

在窗体调整事件大小( 重新恢复Begin & amp; 在重新缩放End) 上使用以下代码 :

protected override void OnResizeBegin(EventArgs e) 
 {
    SuspendLayout();
    base.OnResizeBegin(e);
 }

protected override void OnResizeEnd(EventArgs e) 
 {
    ResumeLayout();
    base.OnResizeEnd(e);
 }
