  Hi there,
  
  I have used the following script to set focus on a RadTextBox but both scripts are not working. That is the script can't find the control on the page. I have a master page and my form that contains the RadTextBox is in a contentpane.
  
  Script 1
   function setFocusToRadInput()
         {
             var radInput = window["<%= radInput1.ClientID %>"];
             radInput.Focus();
         }
  
  Script 2
    function setFocusToRadInput()
         {        

         var radInput = $find("<%=txtApplicationName.ClientID %>");//this returns a null

   

   

             radInput.Focus();
         }

  ID for my RadTextBox control is txtApplicationName. Any help will be appreciated.
  
  Thanks
  Jeff

  Hi Radoslav,
  Thank you for the response.
  The example you attached seems to work.  However, if I transfer the javascript code to a separate javascript file, will this code still work?
  I usually do not like putting javascript code on a html web page.
  
  Also, I see that you used the RadCodeBlock control, must this control be used to get the javascript code to work?
  Do I have to use the script below? ( I have the Telerik.Web.U dll reference in my project but I don't seem to get javascript intelligence to work). This script is found within the RadScriptManager in the MasterPage.master.
  ===============================================================================================

  <%--Needed for JavaScript IntelliSense in VS2010--%>

   

  <%

   

  --For VS2008 replace RadScriptManager with ScriptManager--%>

   

   

   

  <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

   

   

   

  <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

   

   

   

  <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />

   

   

   

  </Scripts>

   

  ===============================================================================================
  
  
  
  So I am trying to accomplish the following:-
  
  1) Have the javascript code in a separate javascript file
  2)Reference the javascript file from a master page
  3) Call the javascript functions from web page that exist in a contentPlaceholder.
  
  Thank you in advance and I look forward to hearing from you soon.

  Hello Jeffrey,
  
  RadCodeBlock is used to allow server and client script to work well together with AJAX updates. More information you could find in this documentation topic:
  http://www.telerik.com/help/aspnet-ajax/ajxradscriptblockradcodeblock.html
  Also the <% %> block only work in the aspx page itself, not in external files. More information you could find in this links:
