C# 中DataGridView和ListView闪烁问题的解决方法

方法一
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,

// <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();    }}

  

方法二
直接写一个扩展方法,使用反射,直接上代码,将此类定义给DataGirdView或ListView所在的窗体类外面即可

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);    }}//调用方法public Form1(){    InitializeComponent();    DataGridView1.DoubleBufferedDataGirdView(true);}

  其实很简单的,一看代码就能明白,使用双缓冲解决闪烁问题
