【问题描述】：

这个控件的原因是让listview在滚动时停止闪烁。 闪烁已停止并且工作正常，但 listview 控件没有与常规 winforms listview 相同的属性。

在此屏幕截图中，带有 ListView Tasks 窗口的列表视图是常规列表视图，而空的较小矩形是自定义控件。

这是自定义控件列表视图代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace FileSearcher

    public partial class ListViewCostumControl : UserControl
    
        public static ListViewControl lvnf;

        public ListViewCostumControl()
        
            InitializeComponent();

            lvnf = new ListViewControl();
            lvnf.Location = new Point(50, 50);
            lvnf.Size = new Size(50, 50);
            lvnf.View = View.Details;
            lvnf.Dock = DockStyle.Fill;
            lvnf.SuspendLayout();
            lvnf.LabelEdit = true;
            lvnf.HeaderStyle = System.Windows.Forms.ColumnHeaderStyle.None;
            lvnf.Columns.Add("", 984, HorizontalAlignment.Left);
            lvnf.Sorting = SortOrder.None;
            this.Controls.Add(lvnf);
            lvnf.ResumeLayout(false);
        

        public class ListViewControl : System.Windows.Forms.ListView
        
            public ListViewControl()
            
                //Activate double buffering
                this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);

                //Enable the OnNotifyMessage event so we get a chance to filter out 
                // Windows messages before they get to the form's WndProc
                this.SetStyle(ControlStyles.EnableNotifyMessage, true);
            

            protected override void OnNotifyMessage(System.Windows.Forms.Message m)
            
                //Filter out the WM_ERASEBKGND message
                if (m.Msg != 0x14)
                
                    base.OnNotifyMessage(m);
                
            
        

        private void ListViewNFTest_Load(object sender, EventArgs e)
        

        
    

【参考方案1】：

我自己添加了列，并获得了与原始列表视图控件相同的视图。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace FileSearcher

    public partial class ListViewCostumControl : UserControl
    
        public static ListView lvnf;

        public ListViewCostumControl()
        
            InitializeComponent();

            lvnf = new ListView();
            lvnf.Location = new Point(50, 50);
            lvnf.Size = new Size(50, 50);
            lvnf.View = View.Details;
            lvnf.Dock = DockStyle.Fill;
            lvnf.HideSelection = false;
            lvnf.MultiSelect = false;

            //lvnf.SuspendLayout();
            //lvnf.LabelEdit = true;
            //lvnf.HeaderStyle = System.Windows.Forms.ColumnHeaderStyle.None;
            lvnf.Columns.Add("Path", 212, HorizontalAlignment.Left);
            lvnf.Columns.Add("Path", 90, HorizontalAlignment.Right);
            lvnf.Columns.Add("Last modified", 120, HorizontalAlignment.Left);
            lvnf.Columns.Add("", 984, HorizontalAlignment.Left);
            lvnf.Sorting = SortOrder.None;
            this.Controls.Add(lvnf);
            lvnf.ResumeLayout(false);
        

        public class ListView : System.Windows.Forms.ListView
        
            public ListView()
            
                //Activate double buffering
                this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);

                //Enable the OnNotifyMessage event so we get a chance to filter out 
                // Windows messages before they get to the form's WndProc
                this.SetStyle(ControlStyles.EnableNotifyMessage, true);
            

            protected override void OnNotifyMessage(System.Windows.Forms.Message m)
            
                //Filter out the WM_ERASEBKGND message
                if (m.Msg != 0x14)
                
                    base.OnNotifyMessage(m);
                
            
        

        private void ListViewNFTest_Load(object sender, EventArgs e)
        

        
    

工作良好，没有任何闪烁。
