  Hi, I have a treeview as shown in the image.
  
  Suppose I selected “Root1 Level2” node.
  
  Is there any way to get “Root1” node?
  
  

  Here is the sample code.

  Hi Youkou,

  To get the root-level parent node of any selected node, you can write a simple method to iterate all the nodes and find the level-0 node for the selection. Please see the attached sample project showing a simple implementation of the same.

  Hi Kartik,
  
  Thank you for the sample code. It works well. The idea of flattening a tree structure into a list, then use Level property to find the root node is quite nice.
  
  Best regards
