title: how to get multiple values from selected - asp.net
body: <p>How can I get chosen values from <code>select</code> tag after click button? Here I get html <code>select</code> with multiple choose. <br><br>
  <code>selTest.Value</code> returns only first selected item.</p>
  
  <pre><code>    &lt;select runat="server" id="selTest" name="selTest" data-placeholder="Choose a Country..." class="chzn-select" style="width:350px;" tabindex="4"&gt;
        &lt;option value=""&gt;&lt;/option&gt; 
        &lt;option value="United States" selected="selected"&gt;United States&lt;/option&gt; 
        &lt;option value="Western Sahara"&gt;Western Sahara&lt;/option&gt; 
        &lt;option value="Yemen"&gt;Yemen&lt;/option&gt; 
        &lt;option value="Zambia" selected="selected"&gt;Zambia&lt;/option&gt; 
        &lt;option value="Zimbabwe" selected="selected"&gt;Zimbabwe&lt;/option&gt;
      &lt;/select&gt;
  
     &lt;asp:Button ID="testBt" runat="server" OnClick="testBt_Click" Text="ds" /&gt;
  </code></pre>
  
  <p>Code behind:</p>
  
  <pre><code>protected void testBt_Click(object sender, EventArgs e)
  {
  
  }
  </code></pre>
