Hello All,
I am using the GroupingStore along with an Editorgrid to show groups of data, and my

GroupStore looks like :
Code:
var store = new Ext.data.GroupingStore({
        url: 'sample.xml',
        groupField: 'imntClsfTypNm',
        reader: new Ext.data.XmlReader({
            record: 'accountPosition'
            }, [
                {name:'accId'},
                // truncated
               ]

EditorPanel looks like:
var grid = new Ext.grid.EditorGridPanel({
                    renderTo: Ext.getBody(),
                    title: 'Account Positions',
                    stripeRows : true,
                    store: store,
                    columns: [ {header: "Actions", width: 150, dataIndex: 'actions' },
                              {header: "Acct#",  width: 100, dataIndex: 'accId',
                                 summaryType: 'count',
                                 summaryRenderer: function(v, params, data){
// using the /examples/ux/GroupSummary.js

                                    return ("Total" + Group by value);  // not sure how to get group by value in groupstore here
                                    }
