Question

我在C＃项目中添加了一个新类。非常简单，基于我发现的许多例子：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace GENIO_Viewer
{
    class DBTableLayoutPanel : TableLayoutPanel
    {
        public DBTableLayoutPanel() : base()
        {
            DoubleBuffered = true;
        }
    }
}

然后我编辑了设计器类文件以使用修改后的对象（代码缩减）：

private void InitializeComponent()
{
    this.tableLayoutPanel = new DBTableLayoutPanel();
    // tableLayoutPanel
    // 
    this.tableLayoutPanel.AutoSize = true;
    this.tableLayoutPanel.BackColor = System.Drawing.Color.Black;
    this.tableLayoutPanel.ColumnCount = 1;
    this.tableLayoutPanel.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 50F));
    this.tableLayoutPanel.Cursor = System.Windows.Forms.Cursors.Cross;
    this.tableLayoutPanel.Dock = System.Windows.Forms.DockStyle.Fill;
    this.tableLayoutPanel.Location = new System.Drawing.Point(0, 24);
    this.tableLayoutPanel.Name = "tableLayoutPanel";
    this.tableLayoutPanel.RowCount = 1;
    this.tableLayoutPanel.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 50F));
    this.tableLayoutPanel.Size = new System.Drawing.Size(555, 359);
    this.tableLayoutPanel.TabIndex = 4;
}

编译好。但是当我在编辑器中显示teh表格时，我遇到了一个问题：

这是为什么？我无法解决我必须做的事情来修复它。

更新

这是设计器文件的完整表单定义。它只有在我注释掉DBTableLayoutPanel行并用注释掉的行代替时才有效。困惑。：

更新：当我继承DataGridView并设置DoubleBuffered时，也会发生这种情况。渲染编辑无法操作。

在其中一个答案中谈到了改变构建模式。由于我的应用程序所依赖的DLL文件，我已将其设置为 x64 位构建模式。如果设置为任何CPU ，我会收到这些构建错误：
