Hi, I have been working on fixing some issues with the behavior of CheckBoxTreeItem. I stumbled across this situation:
When a parent is de/selected, all of its children are set to the same state. However, a CheckBoxTreeItem can be set to indeterminate programmatically (the control itself does not allow indeterminate). Should all children also be set to an indeterminate state? If so, this will put the tree at an "invalid" state where leaf nodes can be indeterminate as well. OTOH, if not, then we are again at an invalid state if all children have the same state, but the parent doesn't. - Nir
