# Delete data

#### There are several ways to delete rows in RealGrid.
When using `Delete in GridView`, you must set gridView.editOptions.deletable = true .

1. Deletion from GridView  
   Method 1 - User deletes by pressing the `Ctrl` + `Del` (windows) or `Ctrl` + `Fn` + `Backspace` (mac) keys.  
   Method 2 - [GridBase.deleteSelection()](/refs/Class/GridBase#deleteselection)  

2. Deletion from DataProvider  
   [dataProvider.removeRow()](/refs/Class/LocalDataProvider#removerow), [dataProvider.removeRows()](/refs/Class/LocalDataProvider#removerows)


> For information on whether or not to display the deleted row on the screen, check [Tips related to deleting rows](/guides/tip/delete).  
> Check [event occurrence order](/guides/events/event-order) for events that occur when deleting.
