C#Windows窗体:拆分器闪烁

问题描述：

我遇到以下问题:我在窗体中放置了一个拆分器控件(而不是拆分容器)，并添加了2个面板.分离器工作正常，但是当我移动分离器时，它开始闪烁-面板不工作.

I have the following problem: I placed a splitter-control (not split-container) in my form and added 2 panels. The splitter works properly but when I move the splitter, it starts to flicker - the panels dont.

使用分割容器可以获得相同的结果.

I get the same result with a Split-Container.

我尝试了这个，但是没有用

I tried this but nothing works

this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.DoubleBuffer, true);
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
this.DoubleBuffered = true;
...


class XSplitter : Splitter
{
    public XSplitter() : base()
    {
        this.SetStyle(ControlStyles.UserPaint, true);
        this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
        this.SetStyle(ControlStyles.DoubleBuffer, true);
        this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
        this.DoubleBuffered = true;
    }
}

class XPanel : Panel
{
    public XPanel() : base()
    {
        this.SetStyle(ControlStyles.UserPaint, true);
        this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
        this.SetStyle(ControlStyles.DoubleBuffer, true);
        this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
        this.DoubleBuffered = true;
    }
}

我使用Windows 8.1和VS 2010

以下是使用此控件的步骤:

Here are the steps to use this control:

将新类"NonFlickerSplitContainer"添加到C#应用程序中.
用下面显示的C#代码替换自动生成的类代码.
在应用程序中使用NonFlickerSplitContainer对象而不是SplitContainer对象.

Add new class "NonFlickerSplitContainer" to your C# application.
Replace auto generated class code with C# code shown below.
Use NonFlickerSplitContainer object instead of SplitContainer object in your application.

public partial class NonFlickerSplitContainer : SplitContainer
{
   public NonFlickerSplitContainer()
   {
    this.SetStyle(ControlStyles.AllPaintingInWmPaint |
                  ControlStyles.UserPaint |
                  ControlStyles.OptimizedDoubleBuffer, true);

    MethodInfo objMethodInfo = typeof(Control).GetMethod("SetStyle",BindingFlags.NonPublic|BindingFlags.Instance);

    object[] objArgs = new object[] { ControlStyles.AllPaintingInWmPaint |
                                      ControlStyles.UserPaint |
                                      ControlStyles.OptimizedDoubleBuffer, true };

    objMethodInfo.Invoke(this.Panel1, objArgs);
    objMethodInfo.Invoke(this.Panel2, objArgs);
   }
}
