DataGridView

If there is no data in the datagridview and still I select the empty cell and click on update, I am getting message as updated. but if I click on update directly then I get "There are no records to update". My requirement is if there is no data in the datagrid view and even though we click on the empty cell, it should not get update message. the code I am using is:

if (dataGridView2.SelectedCells.Count == 0 )

           {
               MessageBox.Show("There are no any records to update");
           }
