How to delete the data in Store that's already filtered
Code:
SharpJs.TrPenaltiesStore.filter('DefectId', 'CR01', false, true);
I got two record where DefectId = CR01 from this filter action
Then I want to remove the records
Code:
SharpJs.TrPenaltiesStore.remove();
After process that code, all of data except that DefectId = 'CR01' is removed
I want to keep that data but it's removed from the store and the data that I want to remove is still keep in the store.
How to handle this? Please help me Thanks
