TreeView Auto-select checked sibblings for deeper levels

[Administrator]

I have noticed that the level directly below the top level will automatically select/deselect itself when all nodes show checkboxes (ShowCheckBox = true).

A brilliant feature - but is there a way that this principle extends to deeper levels?
i.e. I check a node in level 2 and all its sibblings (in level 3) get automatically checked?

Hi Marcel,

That functionality can be turned on for any node by marking it as an InteractiveCheckBox.

treeNodeAdv1.InteractiveCheckBox = true;

You can also change this property in the Node Collection editor.
