    <p>I'm using ExtJS 3.3.0 with a datagrid that consumes a JSON data store (Ext.data.GroupingStore).</p> <p>When I'm not grouping by a column, I can sort just fine, however when grouping by a column, the sort algorithm seems to fall apart.</p> <p>I have another data grid that does server side sorting (and grouping and paging) and this works just fine. Comparing the the code between the two has left me stumped for the difference that's making one work and the other not work.</p> <p>Many thanks in advance.</p> <pre><code> CW.App.FileGrid = { store : null, initComponent: function(){ this.store = new Ext.data.GroupingStore({ autoLoad:true, url:'/sites/files.js', groupField:'modified', // Sort by whatever field was just grouped by. This makes the data // make more sense to the user. groupOnSort:true, remoteSort:false, remoteGroup:false, sortInfo:{ field:'modified', direction:'DESC' }, reader: new Ext.data.JsonReader({ idProperty:'filename', root:'data', fields: [ 'iconCls', { name: 'modified', type: 'date', dateFormat:'timestamp' }, 'description', 'folder', 'filename', 'filesize', 'ext', 'dateGroup'] }) }); // this.store.setDefaultSort('modified', 'DESC'); Ext.apply(this, { store: this.store, loadMask:true, columns: [ { xtype:'actioncolumn', items:[{ getClass:function(v,meta,rec){ return rec.get('iconCls'); } }], width:25 },{ id:'filename', header: "Filename", sortable: true, dataIndex: 'filename' },{ id:'ibmu', header: "iBMU", width:50, sortable:true, dataIndex: 'folder' },{ id:'date', header: "Date", width: 65, sortable: true, dataIndex: 'modified', renderer: Ext.util.Format.dateRenderer('Y-m-d h:i'), groupRenderer:function(v,unused,r,rowIdx,colIdx,ds){ return r.data['dateGroup']; } },{ id:'type', header: "Type", width: 70, sortable: true, dataIndex: 'description' },{ id:'size', header: "Size", width: 50, sortable: true, dataIndex: 'filesize', renderer: Ext.util.Format.fileSize },{ xtype:'actioncolumn', items:[{ icon: '/img/fam/drive_disk.png', tooltip: 'Download file', handler: function(grid, rowIndex, colIndex){ var rec = store.getAt(rowIndex); location.href = Ext.urlAppend('/ibmus/download/', Ext.urlEncode({ folder: rec.get('folder'), filename: rec.get('filename') })); } }] } ], autoExpandColumn:'filename', view: new Ext.grid.GroupingView({ emptyText: 'No files found. Please wait up to 24 hours after activating your account for files to appear.', forceFit:true, groupTextTpl: '{text} ({[values.rs.length]} {[values.rs.length &gt; 1 ? "Files" : "File"]})' }), frame:false, width: '100%', height: 250, collapsible: false, animCollapse: false }); CW.App.AlarmGrid.superclass.initComponent.call(this); } }; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
