How can i loop the grid object to get its elemnts and its values ?  

Answer 1

How do you get the rows from the grid?

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

rows will be an Array of Record objects.

Answer 2

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); }

Answer 3

That's actually quite wrong.

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

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