Limiting depth of TreeGrid

[Renogen]

I need to limit the max depth a user can drag and drop a node.

For eg. Taking root level as level 1, i want to limit user to only drop till the 3rd level, in other words, only a tree of 3 levels is allowed.

I tried to change the node values onDropEvent, but it will create a duplicate with the changed valued and end up causing alot of errors due to duplicate keys.

Kindly advise, thanks!

First occurrence for "smartgwt treegrid limit depth" and no answer yet...

Here is what I did:

// the default value, can be ommited
treeGrid.getTree().setIsFolderProperty("isFolder");

After that, I created a property on my DataSource with the name isFolder and set "true" or "false" accordingly for each record.
