->note If you are using the [OnRead event to implement the data operations manually](slug://components/grid/manual-operations), you must not use the `.Add()`, `.Remove()` or `.Clear()` method of an observable collection - the grid monitors that collection and it fires the `OnRead` event when it changes, so calling those methods will result in an infinite loop.
