  Hello
  
  I am using v4.0.20151.38 and trying C1List.C1Combo.EmptyRows = True
  
  .MaxDropDownItems = 10
  
  .ComboStyle = C1.Win.C1List.ComboStyleEnum.DropdownCombo
  
  But when there is say only 1 item, the dropdown list is exactly 1 row tall.
  
  I want the dropdown list to be always 10 rows tall with the space at the bottom. Am I missing something ?
  
  Thanks
  
  Brian

  Also, I have a date column with
  
  .Columns(“Posted”).NumberFormat = “yyyy-MM-dd hh:mmtt”
  
  but if the value is NULL it shows as 0001-01-01 12:00
  
  Is there a way to leave the column blank?
  
  I tried a ValueItem with .Value=“” and .DisplayValue = “” but that did not work. Is there a way to do something like NullText ?
  
  Thanks

  Mr Sharma,

  1. I will have a look at the demo.
  2. Just to clarify, it is not that I am leaving the column blank, it is that the underlying data for the date is a NULL and I want the column to display as blank rather than 0001-01-01 12:00
     
     Thanks a lot

  Mr Sharma,
  
  On the demo the list is only 4 rows high even though the MaxDropDownItems=10 and EmptyRows=true.
  
  Yes the demo null values are showing as blanks. The only difference to me is that you use the datasource as a DataTable where I have a List. I will look more closely at this.
  
  Thanks

  Mr Sharma,
  
  My datatype in my List was the problem, I had Date instead of Date? so the Nothing value was being kept as 0001-01-01 12:00 and obviously the combo displayed that.
  
  Thank you very much

  Oh, ok, the EmptyRows problem is a bug then? Probably won’t get fixed for my 2015 version then.

  Hello,

  Apologies for the delay in response.
  
  This issue has been fixed back in 2021 builds and Empty rows are shown in Combo dropdown as per MaxDropDownItems when EmptyRows is set True
  
  Please update your project with the latest builds to resolve this issue.

  Regards,
  
  Prabhat Sharma.

  Mr Sharma,
  
  Lol. Better late than never. Only this week did I complete upgrade from v2015 for v2023 and I saw that it was indeed fixed.
  
  Thanks
