body: <p>So with this code.</p>
  
  <pre><code>public partial class SiteMaster : System.Web.UI.MasterPage
      {
  
          public string feedbackPostback = "false";
  
          protected void Page_Load(object sender, EventArgs e)
          {
  
          }

  <p>How to I access <code>feebackPostback</code> from:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(function () {
          $('.slide-out-div').tabSlideOut({
              tabHandle: '.handle',                     //class of the element that will become your tab
              pathToTabImage: 'images/feedback.gif',    //path to the image for the tab //Optionally can be set using css
              imageHeight: '122px',                     //height of tab image           //Optionally can be set using css
              imageWidth: '40px',                       //width of tab image            //Optionally can be set using css
              tabLocation: 'right',                     //side of screen where tab lives, top, right, bottom, or left
              speed: 300,                               //speed of animation
              action: 'click',                          //options: 'click' or 'hover', action to trigger animation
              topPos: '150px',                          //position from the top/ use if tabLocation is left or right
              leftPos: '20px',                          //position from left/ use if tabLocation is bottom or top
              fixedPosition: false,                      //options: true makes it stick(fixed position) on scroll
              onLoadSlideOut: &lt;%= this.feebackPostback %&gt;
          });
  
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>Currently trying <code>&lt;%= this.feebackPostback %&gt;</code> and returns this error: CS1061: 'ASP.site_master' does not contain a definition for 'feebackPostback' and no extension method 'feebackPostback' accepting a first argument of type 'ASP.site_master' could be found (are you missing a using directive or an assembly reference?)</p>
