Giovanni Montrone wrote in his Code Project article that the best way to avoid listview flicking is forcing it to use DoubleBuffer. He provides a new listview control that inherits from the classic one and adds a new method called SetExStyles() which allows setting the extended styles of the listview.
But I found a comment from Gabriel Szabo explaining how to have the same result without sub classing any control, but using Reflection :
PropertyInfo aProp = typeof(ListView).GetProperty("DoubleBuffered",
BindingFlags.NonPublic | BindingFlags.Instance);
aProp.SetValue(lvwControl, true, null);
(when lvwControl is the name of your listview control)
Many thanks Gabriel !!
