  Hi -- I have a RadComboBox on parent page.  When I click a button on the page, it opens up a Popup.  The Popup builds a string and populates a TextBox with it.  When user closes the Popup, I want this string to be added to the RadComboBox on the parent page.  I can't seem to be able to pass this string to the parent page.  If I use a TextBox instead of RadComboBox, I can update it from the client code on OnClientClose event but there doesn't seem to be a way to access RadBoxComboItems in client code.
  
  I tried using the code posted in some demos such as "var comboboxItem = new Telerik.Web.UI.RadComboBoxItem()".
  But even though I have "<%@ Register Assembly='Telerik.Web.UI' Namespace='Telerik.Web.UI' TagPrefix='telerik' %>, it complains that "Telerik" is not defined.  We are using Telerik Rad controls version "Q1-2010". 
  
  If we cannot create RadComboBoxItem in client code using this method described in the demo for this verison of telerik, is there any other way to do what I am trying to do?
  
  Thanks
  Sandhia

  Hello,
  
  One possible approach to achieve your scenario is the following (a RadWindow control is used as pop up control):
  

  <telerik:RadCodeBlock runat="server">

      <script type="text/javascript">

      function onClientBeforeClose(sender, args) {

          var textBoxJQueryObj = $telerik.$("[id$='_RadTextBox1']");

          var textBoxObject = $find(textBoxJQueryObj.attr("id"));

          var combo = $find('<%= RadComboBox1.ClientID %>');

          combo.trackChanges();

          var comboItem = new Telerik.Web.UI.RadComboBoxItem();

          comboItem.set_text(textBoxObject.get_textBoxValue());

          comboItem.set_value(textBoxObject.get_textBoxValue());

          combo.get_items().add(comboItem);

          combo.commitChanges();

      }

      </script>

  </telerik:RadCodeBlock>

  <telerik:RadComboBox ID="RadComboBox1" runat="server">

      <Items>

          <telerik:RadComboBoxItem Text="item1" />

      </Items>

  </telerik:RadComboBox>

  <telerik:RadButton ID="RadButton1" runat="server" OnClick="RadButton1_Click" />

  private RadWindowManager winmgr = new RadWindowManager();

  protected void Page_Load(object sender, EventArgs e)

  {

      form1.Controls.Add(winmgr);

  }

  protected void RadButton1_Click(object sender, EventArgs e)

  {

      RadWindow window = new RadWindow();

      window.Height = 500;

      window.Width = 500;

      window.Modal = true;

      window.Visible = true;

      window.Enabled = true;

      window.VisibleOnPageLoad = true;

   

      RadTextBox textBox = new RadTextBox();

      textBox.ID= "RadTextBox1";

      textBox.Text = "Enter Item";

      textBox.Visible = true;

      textBox.Width = 100;

      window.ContentContainer.Controls.Add(textBox);

      window.OnClientClose = "onClientBeforeClose";

      winmgr.Windows.Clear();

      winmgr.Windows.Add(window);

  }

  
  I hope this helps.
