Thanks Jay for your response.
I tried your code and it still flickering a lot. To demonstrate it, you can
grab a listview, create 3 columns - name, value, timestamp, in form_load
event to add 50 items into that listview as Item1 - Item49, add a timer to
your windows form, set the timer interval to 100 ms, in the event handler,
add the code to update the value and timestamp
Random r = new Random();
listView1.BeginUpdate();
for (int i = 0; i < 50; i++)
{
listView1.Items[i].SubItems[1] = r.Next(0, 10000).ToString();
listView1.Items[i].SubItems[2] = DateTime.Now().ToLongTimeString();
}
listView1.EndUpdate();
Anyone could make the flickering goes away would be my star!!!! or any other
solution to this fast updating problem?
Thanks in advance!

use following code in the contructor.
// set control styles
this.SetStyle(ControlStyles.DoubleBuffer, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.ResizeRedraw, true);

news:#R**************@TK2MSFTNGP10.phx.gbl... Hi,
I have a windows application that uses the listview to display about 50
items in detailed view - 4 columns. The first column is static and other
columns will be updated in 100-1000ms - it looks awful when it's
running -
flickering too much!!!
Anyone know how to solve this flickering problem? or how should I deal
with this issue? I see some other C++ app can display more than 100 items
without any flickering in such as speed. Can we achieve the same effect in C#?
Thanks a lot!
John
