Question

用C#listview控件Details类型，发现当拉动表头调整列宽度过程时，listview会重画，造成不停的闪烁

有什么方法让它在宽度调整完后之后，listview才重画

Answer 1

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++;

}
