title: Add Items to the ComboBox
body: <p>I have a <strong>ComboBox</strong> control.</p>
  
  <p>I bind to this control to the DataSet table.</p>
  
  <p>Here is the code:</p>
  
  <pre><code>comboBox.Items.Add(("Select"));
  comboBox.DataSource = DataSet.ColorTable;
  comboBox.DisplayMember = DataSet.ColorTable.ColorNameColumn.ColumnName;
  comboBox.ValueMember = DataSet.ColorTable.ColorIDColumn.ColumnName;
  </code></pre>
  
  <p>This result I get:</p>
  
  <p><img src="https://i.stack.imgur.com/8w1pY.png" alt="enter image description here"></p>
  
  <p>I want to display on the top of the list <strong>SELECT:</strong> word. So I need to add addition Item to the comboBox control. 
  Here how I implement it:</p>
  
  <pre><code>cmbCategory.Items.Add(("Select"));
  </code></pre>
  
  <p>But the result is still the same as above. I get only colors without <strong>SELECT:</strong> word on the top of the list.</p>
  
  <p>Any idea how I can add this string-<strong>SELECT:</strong> to the ComboBox control and set to this string <code>ValueMember</code>?</p>
