Hi guys!
I'm currently using ultraTree to view and navigate different object sets.
So, I'm stuck with the followin problem -
1. I have a collection, each object of it has a subcollection (typical situation)
2. I expand the node - if it has no child elements it's expansion indicator disappears (it's strange considering that I've set HideExpansionindicators to 'NEVER'). So, after I expanded node - I add a child element to object that is bound to the node. And .... nothing happens - expansion indicator does not appear, I cant see my changes. So, I have to rebind it completely and navigate again to the said node and expand it. It's kinda ugly from my point of view.
Please, help me to find workaround for it.
I'm having a little trouble following this because the property's name is ShowExpansionIndicator, so setting it to 'Never' is supposed to hide it. If you set it to 'CheckOnExpand', then populate the Nodes collection, the expansion indicator will remain.
Just to clarify...
HideExpansionIndicators is a new property that was added to the tree recently in order to support the Windows Vista style view. This property controls whether the expansion indicators are hidden when the mouse moves outside the bounds of the control, just like the ones in Windows Explorer do in Windows Vista.
It does not have any relation to the expanded state of a node or it's child nodes.
