title: Adding Items to Telerik RadContextMenu showing transparent background
body: <p>I have a RadContextMenu in my asp.net web page. This menu has some static items.</p>
  
  <p>I am adding few more options to it from javascript and thats it.</p>
  
  <p>After adding items from javascript right side of contextmenu becomes transparent.</p>
  
  <p>More details:</p>
  
  <p>Following is the javascript code where I am adding few items in existing rad context menu i.e. RadMenu1.
  There are few items already in it and I am adding few more items dynamically in javascript </p>
  
  <pre><code>function ContextMenuOpen(sender, args) 
  {
      var menu = $find("m_c_RadMenu1");
      if (IsMobileBrowser() == false) 
      {
          var evt = args.get_domEvent();
      }
      menu.trackChanges();
      var items = menu._getAllItems()
      menu.get_items().clear();
  
      //menu.commitChanges();
      AddItem("Visit &amp; View Details", "a");
  
      if (selectedRow.findElement("lblTask") != null) {
          var tasklist = selectedRow.findElement("lblTask").defaultValue;
          var taskArray = tasklist.split(',');
  
          for (i = 0; i &lt; taskArray.length; i++) {
              if (typeof (taskArray[i].split('~')[1]) == 'undefined') break;
              AddItem("Perform " + taskArray[i].split('~')[1], taskArray[i].split('~')[0]);
          }
          //rb.AddItem(selectedRow.findElement("lblTask").innerText,4)
      }
      AddItem("Log an Incident", "b");
      if (rb.isLocationSelected == false) {
  
      AddItem("Log a Discrepancy", "c");
  }
  
  
  function AddItem(text, value) {
      var menu = rb.GetMenu();
      var item = rb.GetContextMenuItem(text);
      if (item != null) return false;
      var menuItem = new Telerik.Web.UI.RadMenuItem();
      menuItem.set_text(text);
      menuItem.set_value(value)
      menu.trackChanges();
      menu.get_items().add(menuItem);
      menu.commitChanges();
      return true;
  }

  <p>Everything goes well , but the newly added context menu shows transparent background on rightside , I found it is filling the background only at the area where text is present , on empty area at rightside it is transparent (see attached image )</p>
