title: How to set a value to a combobox from a table
body: <p>i have a datagrid with the fifth column being a combobox.</p>
  
  <p><em>this is the code:</em></p>
  
  <pre><code>            //...
              string rq = "select * from RESview";
              SqlDataReader r = DB.selection(rq);
              while (r.Read())
              { 
                  DATAGRID.Rows.Add(r[0], r[1], r[2], r[3], r[4], r[5], r[6]);
              }
              r.Close();
  </code></pre>
  
  <p>r[4] is the value of what i want the combobox to show,
  the combobox have 4 other option which are the one that can be found in the Database.
  so i'm asking is it possible to set a value to each combobox when adding a row or selecting a combobox value from the already created collection depending on what r[4] is.</p>
