  Good morning,
  
  I’m trying to remove checkbox from parent node only.
  
  Into documentation I see is possible set chebox view for entire TreeView and not only for the node
  
  There is another solution?
  
  Thanks

  Hi Alex,

  Unfortunately, removing the CheckBox from only specific nodes is not directly possible. As a workaround, what you can do is create a Custom presenter to render the nodes for the TreeView. In the presenter, you can check whether you need to show the checkbox for the specific columns or not by associating a boolean flag with the Nodes (using the Tag property). Kindly refer to the attached sample showing the same implementation. In the sample, you will need to set the Tag property of the Parent Nodes to false, to hide their checkbox.

  Best Regards,

  Kartik

  Hi Kartik,
  
  thanks for your example.
  
  I undestood your solution: I will apply it to our implementation (I need to test a field of the Tag (it’s an entity for me).
  
  Very useful
