I am using 'Ext.ux.tree.TreeGrid' and creating new tree grid for my application.
But,I facing a problem to show an empty message for this tree grid.
I wanna to show a message to user if 'Loader' doesn't return any value for tree,then it show a message that
'This product doesn't have any value '.
But,Tree grid doesn't have any config property for it.
Also,I'm not able to get Loader size.[For Loader I'm using 'Ext.tree.TreeLoader' and we get data from JSON]
Please,Suggest me how to show a message if JSON doesn't have any value.
