In my particular mlapp example, if you set a breakpoint on the button push handler you can query the Tree checked nodes property:
app.Tree.CheckedNodes
ans =
4×1 TreeNode array:
TreeNode (Node)
TreeNode (Node2)
TreeNode (Node3)
TreeNode (Node4)
K>> app.Tree.CheckedNodes(2)
ans =
TreeNode (Node2) with properties:
Text: 'Node2'
Icon: ''
NodeData: []
Show all properties
So all four nodes are checked. This is the parent plus three children. In the tree selection change handler you could easily alter the CheckedNodes property for the tree:
app.Tree.CheckedNodes = app.Tree.CheckedNodes(2)
This changes the selection to just the first child node. You may have already done this type of thing in your solution, but you can easily expand on this example for your particular requirements.
