  Hello C1-support,

  as mentioned above I’m searching for a possibility to set the height of a filterdropdown.

  With the latest version 4.5.20202.450 there seems to be a change in behaviour. Now there are max. 5 rows for dropdown height (see attachment FilterDropdown1.jpg).

  

  I think in earlier versions there was a “autoheight”-function which makes it much more comfortable to choose the wanted value, if list is very long.

  Grid and column using following filter-related settings:

  
  Col.ValueItems.Presentation = C1.Win.C1TrueDBGrid.PresentationEnum.SortedComboBox
  Col.ValueItems.Validate = True
  Col.FilterDropdown = True
  
  Grd.Splits(0).DisplayColumns(Col).DropDownList = True
  Grd.Splits(0).DisplayColumns(Col).FilterButton = True
  Grd.Splits(0).DisplayColumns(Col).Button = False
  Grd.Splits(0).DisplayColumns(Col).HeadingStyle.HorizontalAlignment = C1.Win.C1TrueDBGrid.AlignHorzEnum.Near
  Grd.Splits(0).DisplayColumns(Col).Style.HorizontalAlignment = C1.Win.C1TrueDBGrid.AlignHorzEnum.Near
  
  

  Thanks for a short hint.

  Kind regards
  
  Lars

  Hi Prabhat,

  thanks for your reply.

  I played a little bit around with your example and modified it. Your “company”-column works as expected. If you change size of dialog, dropdown grows or shrinks. In my added column (CompanyId) which is based on id/value-translation the behaviour is like written above. Only 5 rows.

  Could you please take an other look at it?

  Kind regards
  
  Lars

  Hi Lars,

  You can use the MaxComboItems property of the ValueItems class to set the number of records to appear in the dropdown. As given in the code snippet below:

  Grid.Columns(ColName).ValueItems.MaxComboItems = 10
  
  

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

  Regards,
  
  Prabhat Sharma.
