Call Back function for TreeStore

Hi,

We are using Ext Js 4.0

We need to perform some operations once the tree store is loaded.

I am using the following code to for the tree store call back operation:

Code:

treestore.load(function (records, operation, success) {
                if (records.length == 0) {
                    Ext.getCmp('pnlPositionSearchErr').show();
                }
            });

The above code is working with the JSON store. But it is not working with the Tree store.

Please help.

Regards,
