TreeView not calling CREATE method for newly appended node

[Z]

When a new node is appended to root, the HierarchicalDataSource correctly calls my remote CREATE method:

var tv = $('#outlineEdit').data('kendoTreeView');
tv.append({ text: 'test', parentId: 6}, null);
me.outlineTreeDataSource.sync();

However, when the node is appended to a parent node, no call is ever made to the remote server but the node is visually appended.  

var tv = $('#outlineEdit').data('kendoTreeView');
tv.append({ text: 'test', parentId: 6}, tv.findByText("Child 1.2"));
me.outlineTreeDataSource.sync();

I haven't found any example or documentation that shows how to do this 'correctly'.  Please advise!

Hello Zaryn,

You need to call the sync method of the child dataSource:

var tv = $('#outlineEdit').data('kendoTreeView');
var parentNode = tv.findByText("Child 1.2");
tv.append({ text: 'test', parentId: 6}, parentNode);
tv.dataItem(parentNode).children.sync();

Ah!  Thank you :)

I think that would be very information to document on the HierarchicalDataSource page and the TreeView page!  It's not documented on either one currently, or in any of the examples.

Hello Zaryn,

Indeed, synchronization of nodes is not well documented, and there are not any good examples on TreeView editing at this time. We have this on our to-do list for future releases.
