推荐答案

由于控件重画而发生闪烁.
使用 control.DoubleBuffered 属性.将其设置为true.
DoubleBuffered允许Control使用辅助缓冲区重绘其表面以避免闪烁.

在.cs页面中编写以下功能

Flickering occurs due to control Repainting.
use control.DoubleBuffered property. set it to true.
DoubleBuffered allows Control redraws its surface using secondary buffer to avoid flickering.

write following function in .cs page

public static void enableDoubleBuff(System.Windows.Forms.Control cont)
        {
            System.Reflection.PropertyInfo DemoProp = typeof(System.Windows.Forms.Control).GetProperty("DoubleBuffered", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
            DemoProp.SetValue(cont, true, null);
        }

在InitializeComponent()之后在表单构造函数中调用函数

call function in form constructor after InitializeComponent()

this.DoubleBuffered = true;
enableDoubleBuff(TableLayoutPanelName);
