Delete

AllowDelete adds a delete action to each row in the grid, and to the edit and view pages. Each one asks for confirmation first.

resource.AllowDelete();

Confirmation textCopy Anchor Link

Change what the confirmation says:

resource.AllowDelete(delete =>
{
    delete.Title = "Cancel this booking?";
    delete.Message = "The booking and its payment history will be removed.";
    delete.ConfirmLabel = "Delete booking";
    delete.CancelLabel = "Keep it";
});

To change the defaults for every resource, see global labels.

When a delete failsCopy Anchor Link

If the database refuses the delete, for example because other records still point to it, the record stays and the page shows an error. The exception is logged as a warning.

There's no hook to run before a delete. To block one with your own message, or to clean up related data, use a custom data source and return a validation error from DeleteAsync. A database constraint or cascade works too.
