  Actually you can specify this feature for each indidual item (see e.g. the designtime editor for item). Example:
  ElXTree.Items[0].Multiline := false;
  ElXTree.Items[0].WordWrap := false;
  ElXTree.Items[0].Height := 50;

  I would like an option to set the number of MaximumLines for each row as a default for new items and be able to alter this quantity for individual items.

  
  

  Using the Height for this is for the component code, not for developer code.

  
  

  I tried 

      NewItem.MultiLine       := True;

      NewItem.WordWrap        := False;

      NewItem.Height          := 50; // 3 * NewItem.Height;

  and

      NewItem.MultiLine       := False;

      NewItem.WordWrap        := False;

      NewItem.Height          := 50; // 3 * NewItem.Height;

  
  

  but I do not see more than one line.

  
  

  AdjustMultiLineHeight := True.

  
  

  What else needs to be done?

  I am sorry, example was certainly perfectly wrong (copy&paste error):

  ElXTree.Items[0].Multiline := true;
  ElXTree.Items[0].WordWrap := true;
  ElXTree.Items[0].Height := 50;

  
  

  If you don't enable Wordwap, there will be certainly no lines.

  Also, it would be useful to have a property named like ElXTree.AutoItemHeight : Boolean that the XTree would then, if true, include as many lines as is necessary to display all the lines.

  I have set the following for all lines as they are read in from a file.

  
  

  NewItem.Multiline := true;
  NewItem.WordWrap := true;
  NewItem.Height := 50;

  
  

  All rows are wordwrapped and multi-line, but only the first is 3 lines in height. All of the other lines show the tops of the 2nd line, but are still only one line in height.

  
  

  What can I do to make this work?

  
  

  Thanks.

  Without seeing the effect / parths of the code one can only guess. 

  Only issue I can imagine that you don't switch of/prohibit repaints (using the Update) pattern while you are reading in the lines.
