[Solved] Automatic start/refresh of ListBox


You need a timer that each time it runs, either update the list view’s current items or just clear and re-add new items:

Timer timer = new Timer{ Interval = 60000, Enabled = true };  //every minute
timer.Tick += (s, e) =>
{
    chatverlauf.Items.Clear();
    var StatusList = ... // get the list of servers status
    chatverlauf.SuspendLayout();
    foreach(var s in StatusList)
    {
        chatverlauf.Items.Add(new ListViewItem(new string[]{s.Name, s.Status});
    }
    chatverlauf.ResumeLayout();
};
