title: Refreshing Combobox and Datagrid after deleting or adding data
body: <p>I am on a roll today.</p>
  
  <p>Basically, after adding data via ComboBox to SQL I would like the ComboBox to auto refresh to show the updated data. Likewise, after deleting data in a Datagrid, I need the datagrid to referesh and show updated data from SQL.</p>
  
  <p>I have tried:</p>
  
  <pre><code>ComboBox1.Refresh()
  </code></pre>
  
  <p>and:</p>
  
  <pre><code>DataGridView1.Refresh()
  </code></pre>
  
  <p>and:</p>
  
  <pre><code>Form1.Refresh()
  </code></pre>
  
  <p>None of them work.</p>
  
  <p>Any ideas?</p>
