How to count the number or records present in the TreePanel

[pawan_chand]

Hi Sencha,I am using a TreePanel where we show the records in the treepanel on the button submission. I want to get the number of records present in tree. I am unable to fetch this. My code below:

var QryInfoTreePanel = new Ext.tree.TreePanel({
        autoHeight: true,
        id: 'queryInfoTreePanel',
        enableDD: false,
        singleExpand: true,
        dataUrl: '/Administration/AdhocQryInfo/AdhocQryInfoTree', 
       rootVisible: false,
        root: { id: 'root', nodeType: 'async' }, 
       title: 'Adhoc Query',
        listeners: { 
           click: function (node, e) { 
               if (node.leaf) {
                    qryID = node.id; 
                   if (qryID < 0) {
                        resetAll();
                    } 
                   else { 
                       GetAdhohQryInfoById(qryID);
                        //adhocQryParamStore.load({ params: { iQryId: 1} }); 
                       adhocQryParamStore.load();
                    }                }
            }        }
    });
and on the button clicking                 


Ext.getCmp('queryInfoTreePanel').getLoader().dataUrl = '/Administration/AdhocQryInfo/AdhocQryInfoTree?sQryTypeSd=' + qryTypeValue + '&sQryRptCategorySd=' + reportCategoryValue;                Ext.getCmp('queryInfoTreePanel').getRootNode().reload();
