title: Store temporary data on a DataGridView C#
body: <p>Can I make my datagridview a container of a temporary data? I don't want to add my datas directly I just wanted it to be stored in a datagridview just like a container. 
  is that possible?</p>
  
  <p>I'm thinking of a listbox which will store the user's choices in a combobox. I don't want to add it directly to the database because the datas thre is temporary the user might change/update his choices. </p>
  
  <p>I have a separate button which will add all of them when the user clicks a submit button. </p>
  
  <p>Any examples?? suggestions? Thanks</p>
