Pass the TreeNode to the moveNode event

So when moving nodes when drag/drop I want to check the level of the node. When the level is larger than 1 I don’t want it to be allowed to drag n drop.

I’m implementing this via the onMoveNode($event) but index always give back 0. Even if i go 4 levels deep or something.

I have had a similar issue. The to passed in the $event seems to be “detached” from the tree. My work-around has been to find the node in the treeModel & get its level or other properties from there:

/** TreeView mouse event handler */
public onTreeViewMoveNode(treeNodeMoveEvent: { eventName: string, node: any, to: { index: number, parent: any }, treeModel: TreeModel }): void {
	const parentTreeNode = treeNodeMoveEvent.to.parent.virtual ? undefined : treeNodeMoveEvent.treeModel.getNodeById(treeNodeMoveEvent.to.parent._id);
	const parentNodeLevel = parentTreeNode ? parentTreeNode.level : undefined;
	// Do something ...
}

Reopening for repoholder to see.

To summ it up: @adamkleingit : ' I think what could be helpful is to pass the TreeNode in addition to the node data - and then you can get the level.'
