  This fiddle demonstrates my issue:

  I am using the formatItem event of TreeView to place CSS classes on the tree node based on information in the node’s dataItem. When I update the dataItem and call TreeNode.refresh(), the format call is not updating the content. Please advise how to have a tree node’s refresh after change to dataItem and call the formatItem.

  Hi Andrew,

  You may use the loadTree of TreeView to update the tree view using the updated itemsSource. Please refer to the code snippet and the sample below:

  theTree.selectedNode.dataItem.flag = flip;
  theTree.selectedNode.refresh();
  theTree.loadTree(true);
  

  You may also refer to the sample below:
