  Hello,
  
  I notice then with a c1List.C1Combo,while scrolling down the dropdown list with the arrowkey, when you get to the 10th item at the bottom of the window the list redraws so that the highlight jumps back to the top of the dropdown window and keeps doing that as you work thru the list.
  
  It is weird because at first you think that you reached the end of the list and started over, only to realize that you are actually still doing down.
  
  Is there a way to make it behave “normally” so that the highlight stays at the bottom of the window?
  
  Regards
  
  Brian

  Hello Brian,

  This is the designed behavior as per the MaxDropDownItems property which allows drawing the number of dropdown items as per its value.
  
  As per your suggestion, it will draw every single item after the MaxDropDownItems value which can impact the performance so in this case, you can set the MaxDropDownItems property to the number of total items in the dropdown if they are less in number to achieve your desired result.

  If you need any other help, please let us know.

  OK. It just looks weird that you are supposed to be scrolling down and the cursor keeps jumping back to the top.
