title: Setting the value of a jQuery Multiselect DropDownList to "All" on page load
body: <p>On my page, I have a series of jQuery DropDowns with this coding on the ASP page (some are slightly altered, but that's not relevant):</p>
  
  <pre><code>jQuery(document).ready(function () {
      jQuery(function () {
      jQuery("#UCStyle1 select").multiselect({
          header: true,
          height: 175,
          minWidth: 240,
          size: 3,
          classes: '',
          checkAllText: 'Check all',
          uncheckAllText: 'Uncheck all',
          noneSelectedText: '0 Selected',
          selectedText: '# selected',
          selectedList: 0,
          show: null,
          hide: null,
          autoOpen: false,
          multiple: true,
          position: {},
          appendTo: "body"
      });
      });
  </code></pre>
  
  <p>In the code-behind, if I want to select a single value in one of these dropdowns on page load, I can do it this way:</p>
  
  <pre><code>sCountry.SelectedValue = "USA";
  </code></pre>
  
  <p>How do I do it if I want to select <strong>all</strong> the values in the multiselect?</p>
