How do I delete a data that is bound with access and displayed on a data grid view?

So I've used a binding navigator and when I press the delete item, the row is deleted, but when I leave the program and go in it again, the deleted row is still there in the data grid view.

What I have tried:

For the delete item:

Private Sub BindingNavigatorDeleteItem_Click(sender As Object, e As EventArgs) Handles BindingNavigatorDeleteItem.Click
        DataBindingSource.RemoveCurrent()
    'I've also tried including the code below

    TableAdapterManager.UpdateAll(UserDataDataSet)

End Sub

For the save item:

Private Sub bnMonitorHeartRateSaveItem_Click(sender As Object, e As EventArgs) Handles BindingNavigatorSaveItem.Click

Try
    DataBindingSource.EndEdit()
    DataTableAdapter.Update(UserDataDataSet.Data)
    MessageBox.Show("Data Saved")
Catch ex As Exception
    MessageBox.Show("error occurred while saving data")
End Try
