i have to get record in function so i can update field of record and it will be dirty automatic. So on cancel i will discard all my changes for that perticular row

Answer 1

The combobox select event don't have all these parameters, the parameters it actually receives are combobox, newValue, oldValue, eOpts from there you can get your "row record" from your editor componenet like this.

autoPopulateCsid: function(combobox, newValue, oldValue, eOpts) {
    let myRecord = combobox.up('editor').context.record;
     myRecord.set('collateralAgreement',newValue);

}

If you dont use myRecord.commit(), the record will be marked as dirty, after that if you want to discard those changes you can use rejectChanges() in the store of your grid.
