[C#] DataGridView 和 DoubleBuffered

在官方文章 - DataGridView.ColumnHeadersHeightSizeMode Property 發現這段文字說明

The DataGridView control does not support double buffering. If DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.

所在環境也是有自訂 DataGridView 並開啟 DoubleBuffered 來使用，一直以來沒有出現大問題，測試理解何謂 visual feedback 效果

自訂 DataGridView 並開啟 DoubleBuffered

using System.Windows.Forms;

namespace AvoidDoubleBuffer
{
    public class UCDataGridView : DataGridView
    {
        public UCDataGridView()
        {
            DoubleBuffered = true;
        }
    }
}

調整欄位寬度

DoubleBuffered = true

未指定 DoubleBuffered

調整欄位順序

DoubleBuffered = true

DoubleBuffered = true
