If you want to get a particular field from each record:

var data = [];
store.each(function(rec){
    data.push(rec.get('field'));
});


Here is the answer to my question:

for (var i = 0; i < yourGrid.getStore().data.length; i++) { 
    var element = Ext.get(yourGrid.getView().getRow(i));
    var record = yourGrid.getStore().getAt(i);
    alert(record.data.ID);
}


How do you get the rows from the grid?

var rows = grid.getStore().getRange();

rows will be an Array of Record objects.


In order to get DOM of the row you can use following code :

yourGrid.getNode(yourGrid.getStore().getAt(rowIndex)) 

or you can use getNode directly but incase of any headerbar it may not work as supposed to.

yourGrid.getNode(rowIndex)

This will give you the table row.
