Hi,

There are numerous updates in the layout. A possible workaround is to suspend the layout: 

  radListView1.ListViewElement.ViewElement.ViewElement.SuspendLayout();

  m_DataSource = null;
  m_DataSource = new BindingList<Person>();
  for (var i = 0; i < 400; i += 4)
  {
      // Add data
  }

  radListView1.DataSource = m_DataSource;
  radListView1.DisplayMember = "Name";
  radListView1.ValueMember = "ID";

  radListView1.ListViewElement.ViewElement.ViewElement.ResumeLayout(true);

Regards,
Hristo
