Hi Nadia - this sample shows the items edited but it also shows the unedited data.

What I want is to only show the edited data in the grid.  

How I did this before (in previous 8x version it works) is that I filter out the collection that the grid's 'data' property is bound to.  For some reason, going to 9x this no longer works and I had to revert.

Here is the 'showEditedOnly' checkbox changed event:
public onChangedRecordsOnlyCheckboxChanged(event: IChangeCheckboxEventArgs): void {
const aggChanges = this.grid.transactions.getAggregatedChanges(true);
if (event.checked && aggChanges && aggChanges.length > 0) {
// if checked and there are transactions, limit grid data to those rows transacted upon
this.gridData = this.allData.filter((row) => {
return aggChanges.findIndex(changedRow => changedRow.id === row.id) >= 0;
});
} else {
// else go back to all data
this.showAllDataInGrid();
}
}
