title: Add "ALL" option as 1st Selection Of Combobox
body: <p>I am in need of adding in the ALL option as the top choice of a combobox.  I have tried this code below, but All is not addded, what must I alter in order to have that added?</p>
  
  <pre><code>string query = "select [empname] from [server].[dbo].[table]";
  SqlDataAdapter da = new SqlDataAdapter(query, conn);
  conn.Open();
  DataSet ds = new DataSet();
  da.Fill(ds, "tables");
  cbotables.DisplayMember = "empname";
  cbotables.Items.Insert(0, "All");
  cbotables.DataSource = ds.Tables["tables"];
  </code></pre>
  
  <p><strong>EDIT</strong><br>
  I just realized a few things were not showing in my code...my connection string is declared above, and the contents of the combobox display as they should from the database, just no ALL option added.</p>
