Hi,
I am currently using Ext.data.GroupingStore and the displayMsg in Ext.PagingToolbar displays total number of rows instead of total number of groups. This is the JSON string :

Code:
actionErrors : []
actionMessages : []
...
...
totalCount : 156
totalGroup : 78
I just want to display the value of the totalGrp in the displayMsg..but it's displaying totalCount (because of my Ext.data.GroupingStore setup).

//create a grouping store
Code:
var _store = new Ext.data.GroupingStore({
            reader:new Ext.data.JsonReader({
                id: 'mpReader',
                root:'mpRoot',
                totalProperty:'totalCount',
                successProperty : 'success',
                messageProperty : 'message',
                fields:[    
                    {name: 'mpId'},
                    .......,
                    {name: 'groupTag'},
                    .......                    
                ]
            }), 
            proxy:new Ext.data.HttpProxy({
                url: readURL
            }),
            groupField:'groupTag',
            remoteSort: true,
            listeners:{
                load:{scope:this, fn:function() {
                    alert(_store.reader.jsonData.totalGroup);     //this one prints the count correctly = 78
                }}
            }
});
But I am not able to access that "totalGroup" inside my 'Ext.PagingToolbar'....

//the bottom page bar

Code:
var _bbar = new Ext.PagingToolbar({
            store: _store,
            pageSize: 10000,
            displayInfo: true,
            emptyMsg: "No data to display",
            beforePageText : '',
            afterPageText : '',
            displayInfo : true,
            displayMsg: '<b>Displaying '+?????+' Groups</b>'   //what to do here????
});
How do I make this work? How do I read the 'totalGroup' straight from the json???

Thanks
