C#使用ListView控件对数据进行频繁更新时,出现闪烁问题的解决办法

C#中使用ListView控件的时候,频繁更新里面的数据时,会出现闪烁的情况。

解决办法:使用双缓冲,首先对listview类进行重写,然后通过继承重写的类,进行控件的初始化定义之后,再进行频繁数据更新是不会出现闪烁现象的。

//对ListView进行继承重写:
public class DoubleBufferListView : ListView
    {
        public DoubleBufferListView()
        {
            SetStyle(ControlStyles.DoubleBuffer |
              ControlStyles.OptimizedDoubleBuffer |
              ControlStyles.AllPaintingInWmPaint, true);
            UpdateStyles();
        }
    }

下面为使用的一个实例:

//视图函数中定义一个Listview控件:
DoubleBufferListView doubleBufferListView1= new DoubleBufferListView();this.doubleBufferListView1.Location = new System.Drawing.Point(50, 37);
this.doubleBufferListView1.Name = "doubleBufferListView1";
this.doubleBufferListView1.Size = new System.Drawing.Size(400, 191);this.doubleBufferListView1.View = System.Windows.Forms.View.Details;

//添加listview到主视图
this.Controls.Add(this.doubleBufferListView1); //对控件进行列表头的添加 doubleBufferListView1.Clear(); doubleBufferListView1.Columns.Add("Action", 80, System.Windows.Forms.HorizontalAlignment.Left); doubleBufferListView1.Columns.Add("value", 80, System.Windows.Forms.HorizontalAlignment.Right); doubleBufferListView1.Columns.Add("Action", 80, System.Windows.Forms.HorizontalAlignment.Left); doubleBufferListView1.Columns.Add("value", 80, System.Windows.Forms.HorizontalAlignment.Left); //添加行数据 string[] listViewData = new string[4]; listViewData[0] = "Action"; listViewData[1] = "1"; listViewData[2] = "Action"; listViewData[3] = "1"; ListViewItem lvItem = new ListViewItem(listViewData, 0); doubleBufferView1.Items.Add(lvItem);
