I have mouse set to scroll 1 screen at a time, but this does not work in the control. It does nothing.
I fixed by changing
protected override void OnMouseWheel(MouseEventArgs e)
{
_search.EndSearch();
if (SystemInformation.MouseWheelScrollLines > 0)
{
int lines = e.Delta / 120 * SystemInformation.MouseWheelScrollLines;...
