Using MVVM to check boxes in TreeView. Not working when tree is collapsed.

[Jon]

Hi,
I'm trying to user MVVM to bind to a TreeView and send in an array of ids and check the corresponding nodes. The recursive function works when I've expanded the root node. But it doesn't work initially when the root is collapsed.

Here is a JsBin that demonstrates the issue.

Thanks,
Jon

Hello Jon,

By default the TreeView loads the children on demand when the user expands a node. Thus the child nodes will not exist before expanding the root. You should use the loadOnDemand configuration if you wish all nodes to be immediately created. I have updated the jsBin to demonstrate the behavior when the loadOnDemand option is set to false.
