I am trying to create a TreeGrid (as in the example http://dev.sencha.com/deploy/dev/exa.../treegrid.html), but I would like to dynamically change the data displayed in the rows based upon updates from the server. If this were done as a simple GridPanel, I would create a create a store and periodically change the store based upon updates from the server. How do I do the equivalent in the Ext.ux.tree.TreeGrid? The TreeGrid data is a little more complicated becase it involves nested data as "children".
Is there a TreeStore that I should be using instead of just a Store? Does a TreeGridLoader help any (I thought that was for adding data dynamically as child nodes are expanded).
