Hi I need both grouping summary and summary in many gridpanels.
I found example in explorer https://examples2.ext.net/#/GridPane...ping_TotalRow/
But its code is not very reusable.

Vhen I look at sencha examples, there is this one
http://docs.sencha.com/extjs/4.2.0/e...tml?theme=gray
which don't need custom javascript functions

it looks like this is relevant sourcecode:

features: [{
            id: 'group',
            ftype: 'groupingsummary',
            groupHeaderTpl: '{name}',
            hideGroupedHeader: true,
            enableGroupingMenu: false
        }, {
            ftype: 'summary',
            dock: 'bottom'
        }]
but I don't know how to use it in ext.net
I try 
<Features>               
             <ext:GroupingSummary runat="server" GroupHeaderTplString="{name}" id="GridSummary" 
                        HideGroupedHeader="true" ShowSummaryRow="true" />
             <ext:Summary id="RozpocetSummary" runat="server" ShowSummaryRow="true" />                    
</Features>
But id don't work

Is there any reusable way how to get groupingsummary and summary on one grid
