C#彻底解决listview的闪屏问题

也许很多人也遇到这样的问题，连续不断向listview中加载数据时界面会不停的闪烁，当你用listview.BeginUpdate(); listview.EndUpdate(); 虽然可以减轻一些，但也不能彻底消除闪屏。不信？可以试试下面的代码：


public partial class Form1 : Form




...{


private int counter = 0;


public Form1()




...{


InitializeComponent();


}


DoubleBufferListView lv = new DoubleBufferListView();




ListView lv = new ListView();


private void Form1_Load(object sender, EventArgs e)




...{


timer1.Enabled = false;


this.Controls.Add(lv);


lv.View = View.Details;


lv.GridLines = true;


lv.BackColor = Color.Silver;


lv.Columns.Add("aa");


lv.Columns.Add("bb");


lv.Columns.Add("cc");


lv.Height = 300;


lv.Width = 300;


timer1.Enabled = true;


}


private void timer1_Tick(object sender, EventArgs e)




...{


lv .Items.Add(counter.ToString());


counter++;


}


}

解决方法：

使用双缓冲，重写listview


class DoubleBufferListView : ListView




...{


public DoubleBufferListView()




...{


SetStyle(ControlStyles.DoubleBuffer | ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);


UpdateStyles();


}


}


public partial class Form1 : Form




...{


private int counter = 0;


public Form1()




...{


InitializeComponent();


}


DoubleBufferListView lv = new DoubleBufferListView();


private void Form1_Load(object sender, EventArgs e)




...{


timer1.Enabled = false;


this.Controls.Add(lv);


lv.View = View.Details;


lv.GridLines = true;


lv.BackColor = Color.Silver;


lv.Columns.Add("aa");


lv.Columns.Add("bb");


lv.Columns.Add("cc");


lv.Height = 300;


lv.Width = 300;


timer1.Enabled = true;


}


private void timer1_Tick(object sender, EventArgs e)




...{


lv .Items.Add(counter.ToString());


counter++;


}

效果是不是很明显啊？呵呵。
