Im working with ext js 4.0 tree grid. Right now i have my grid totally expanded i mean bottom most child nodes are also expanding again to show the parent tree chain again. Right now the json data im constructing server side. At server side, i find difficult to set leaf true as ther is much logic. Can i do it at client side. Please refer the code. and give me any renderer code to be added if any could solve my problem.

You can hack into the TreeStore and reader. Best place is to do it on the server side.

by overriding the onNodeAdded function in Ext.data.TreeStore....

Ext.create('Ext.data.TreeStore', {
onNodeAdded: function(parent, node){
node.leaf = true;
