如何避免屏幕闪烁

我正在制作一个windows窗体应用程序，我的屏幕主要分为3部分，如

===========================================================================
                    Top panel (it doesn't flicker)
===========================================================================
||         || 'it has a panel & panel contains a table layout,this tabble layout'
||         || 'has a picture box and a label, picture & text of label is'           
||         ||'changed on the click of side bar menu' (PROB: this flickers a lot)
||side bar ||==============================================================
||(doesn't ||'this part also has a panel and panel contains different table'
||flicker) ||'layouts and on the click of a menu, related table layout is shown and'  
||         ||'some of the parts of table layout are created dynamically.'
||         ||           
||         ||                (PROB: this flickers a lot)
||         ||

我搜索了很多，发现这个解决方案无处不在，我试了这个

public constructor()
    {
        InitializeComponent();
        this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
        this.DoubleBuffered = true;
        DoubleBuffered = true;
        SetStyle(ControlStyles.UserPaint |
                      ControlStyles.AllPaintingInWmPaint |
                      ControlStyles.ResizeRedraw |
                      ControlStyles.ContainerControl |
                      ControlStyles.OptimizedDoubleBuffer |
                      ControlStyles.SupportsTransparentBackColor
                      , true);
    }

i also tried this

protected override CreateParams CreateParams
{
get
{
CreateParams handleParam = base.CreateParams;
handleParam.ExStyle |= 0x02000000;   // WS_EX_COMPOSITED       
return handleParam;
}
}

它把我的整个屏幕背景变成黑色。

但问题仍然是一样的，有人能告诉我如何解决这个问题，我在哪里做错了?

如何避免屏幕闪烁

没有更多的继续，我的直觉告诉你，你要么在这些区域添加大量的数据，要么有大量的调整大小。

尝试在任何地方更新屏幕(添加行到listviews/boxes/等)或调整屏幕大小，或任何其他将导致屏幕重绘。例:

public void something_resize(object sender, EventArgs e)
{
    try
    {
        this.SuspendLayout(); 
        // Do your update, add data, redraw, w/e. 
        // Also add to ListViews and Boxes etc in Batches if you can, not item by item.  
    }
    catch
    {
    }
    finally
    {
        this.ResumeLayout(); 
    }
}

将ResumeLayout()调用放在finally块中是很重要的，因为如果因为w/e原因发生异常，你希望你的窗口布局，不管你对异常做了什么。
