回答1:

Try setting these on the store:

remoteGroup:true,
remoteSort: true

And in you sql or what you use to get data out sort by grouping field first.

gridDataStoreObj = new Ext.data.GroupingStore(
{
    remoteGroup:true,
    remoteSort: true,
    proxy: new Ext.data.HttpProxy({url: 'index.php' }),
    method:'POST',
    groupField:'brandName',
    ...     
    sortInfo:{field: 'id', direction: "ASC"},
});

On the server:

select * from table order by brandName, id

This should sort groups themselves.

For extjs 4 and for local sorting, instede of using: groupField: 'mygroupfield' on the store

use:groupers: [{ property: 'tasklist_id', sorterFn: function(o1, o2){} }]

回答3:

In the store use the sort order column as your groupField.

In the grid:

features: [
  {
    ftype: 'grouping',
    groupHeaderTpl: [
      '{[values.rows[0].groupId]}'
    ]
  }
]

Where groupId is the 'id' of the column that you want to display

回答4:

in GroupingStore set property:

sortInfo: {field: 'Sort_order', direction: 'ASC'},
