Sort grid by group sum

[rans]

Hi,

I can't find an option to sort my grid by the group summaryRenderer, how can I do it?sort group.png

var leaderboardGrid = Ext.create('Ext.ux.LiveSearchGridPanel', {
			store: 'leaderboardStore',
			columnLines: true,
			id: 'leaderboardView',
			collapsible: false,
			
			columns: [
				{
					text     : 'User Name',
					flex     : 2,
					sortable : true,
					dataIndex: 'userId',


				}, {
					text     : 'Round',
					width: 90,
					sortable : true,	
					dataIndex: 'cycle',
					
				},{
					text     : 'Points',
					flex     : 1,
					sortable : true,	
					dataIndex: 'point',
					summaryType: 'sum',
					summaryRenderer: function(value, summaryData, dataIndex) {
						return value + ' points';
					},
				},
			],
			features: [{
				id: 'group',
				ftype: 'groupingsummary',
				
				groupHeaderTpl: '{name}',
				
				hideGroupedHeader: true,
				
			}],
			
			height: 350,
			width: 600,
			title: 'Leaderboard',
			
			viewConfig: {
				stripeRows: true
			},


		});

thanks,
Rans

You are going to have to specify your own sorter to sort with your complex criteria. You could also return the group data in the records and sort by that field
