C# 中DataGridView和ListView闪烁有关问题的解决办法

首先定义类，将此类放在datagridview或ListView所在的窗体类外面，然后代码如下，

<span style="font-family:Microsoft YaHei;font-size:18px;">// <summary>/// 双缓冲DataGridView,解决闪烁/// 使用方法：在DataGridView所在窗体的InitializeComponent方法中更改控件类型实例化语句将/// this.dataGridView1 = new System.Windows.Forms.DataGridView();   屏蔽掉，添加下面这句即可/// this.dataGridView1 = new DoubleBufferListView();/// </summary>class DoubleBufferDataGridView : DataGridView{    public DoubleBufferDataGridView()    {        SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);        //UpdateStatus.Continue;        UpdateStyles();    }}/// <summary>/// 双缓冲ListView ，解决闪烁/// 使用方法是在ListView 所在窗体的InitializeComponent方法中，更改控件类型实例化语句将/// this.listView1 = new System.Windows.Forms.ListView();    屏蔽掉， 添加下面语句即可/// this.listView1 = new DoubleBufferListView();/// </summary>class DoubleBufferListView : ListView{    public DoubleBufferListView()    {        SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);        UpdateStyles();    }}</span>

<span style="font-family:Microsoft YaHei;font-size:18px;">public static class DoubleBufferDataGridView{    /// <summary>    /// 双缓冲，解决闪烁问题    /// </summary>    /// <param name="dgv"></param>    /// <param name="flag"></param>    public static void DoubleBufferedDataGirdView(this DataGridView dgv, bool flag)    {        Type dgvType = dgv.GetType();        PropertyInfo pi = dgvType.GetProperty("DoubleBuffered", BindingFlags.Instance | BindingFlags.NonPublic);        pi.SetValue(dgv, flag, null);    }}public static class DoubleBufferListView{    /// <summary>    /// 双缓冲，解决闪烁问题    /// </summary>    /// <param name="lv"></param>    /// <param name="flag"></param>    public static void DoubleBufferedListView(this  ListView lv, bool flag)    {        Type lvType = lv.GetType();        PropertyInfo pi = lvType.GetProperty("DoubleBuffered",            BindingFlags.Instance | BindingFlags.NonPublic);        pi.SetValue(lv, flag, null);    }}</span>

<span style="font-family:Microsoft YaHei;font-size:18px;">public Form1(){    InitializeComponent();    DataGridView1.DoubleBufferedDataGirdView(true);}</span>
