Ok. Sorry for that not clearly description. Let me clarify that with some code...

This is my standard grid

var grid_1 = new Ext.grid.EditorGridPanel({
store: protokol_store,
clicksToEdit: 1,
tbar: [{text: "Zapisz protokó?"}, {text: "Generuj raport"}],
cm: cm
This is my JsonStore

var protokol_store = new Ext.data.JsonStore({
autoDestroy: true,
url: '/grid/students',
root: 'students',
fields: ['name', 'surname', 'index']
This is structure of my Json object returned from
url: '/grid/students',

{'students' => {'name' => 'some name', 'surname' => 'some surname', 'index' => 'some index'}, 'some extra data array' => {'x' => x, 'y' => y}

And after store loading students are filling successfully my grid but i dont know how (if i can) read this extra data from json object to set in example title of my grid
