I have a situation where the data coming in because
of the data coming from two separate tables can have the same ID. The ID is
mapped to the NodeID (DataFieldID) of the tree view. Because
of this I can have two nodes with the same id.
Instead of changing my data model converting the ID (int) to a ID (GUID)
I would like to see if there is a mechanism in the TreeView where I can check
to see if when adding a node check to see if the parent node is accepting a
child or not. The below structure represents my tree structure.
When tree evaluates Node 75 with ParentID 37, I
want it at the bottom node as it’s a folder vs the first 37 as it not a node
that can have children.
NodeID 37 ß I don’t want it here
NodeID 37 ß I want it here
Is there an event I can write code for to interrogate the
node to see if I can add a child?
