  Hello there,
  
  I tried to validate a parameter to make sure the ID is not null or not = 0 (zero) before I open a RadWindow.  Somehow, it displayed an alert message, but it did not open a Radwindow with the information I passed.  Here are my code, please tell me what I missed:
  
  the following code is for adding a "print preview" button on my RadScheduler:
  
  <script type="text/javascript">        
              function pageLoad()
                  {
                      var $ = $telerik.$;
                      $(" <li><a onclick='openRadWin(); return false;'><span>Print Preview</span></a></li>").appendTo($('.rsHeader ul'));
                  }
  
      </script>
  ______________________________________________________________________________
  
  this is my RadWindowManager:
  
   <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
          <Windows>
              <telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="1050px"
                  Height="710px" Title="Individual Calendar" Behaviors="Default" VisibleStatusbar="False"
                  Modal="true">
              </telerik:RadWindow>
          </Windows>
      </telerik:RadWindowManager>
  ______________________________________
  this is a javascript code to validate id=RecordNum before I open a RadWindow:
  
      <table style="width: 100%;">
          <tr>
              <td id="DecoratedControlsContainer">
  
                  <script type="text/javascript">
                       //   <![CDATA[
                          function openRadWin(id)                        
                          {                          
                              
                              if (!id==0)                           
                              {                              
                                  window.radopen("IndividualCalendar.aspx?RecordNum=" + id, "RadWindow1");                                 
                              }
                              else
                              {                          
                                   alert("Please select an individual name!");
                              }                                 
                           }             
  
                     //     ]]>                                                                        
                  </script>
  
              </td>
          </tr>
      </table>
  
  Thanks so much!

  Hello Tiffany,

  You do not pass a variable/value to the openRadWin() function and thus the id variable inside will be undefined, which in turn means that you will always enter the else statement and receive the alert.

  What I can suggest is that you create a global variable that you modify according to your custom logic and pass it as an argument to the function when you create the li node.

  For your convenience I created and attached a simple page illustrating the approach. Please note that I do not have your whole code, so I moved the client script to the click of a button, but that should not make a difference. I also enabled the statusbar so that you can see the entire url with the query string. You can find a video from my experiment on the following link: http://screencast.com/t/YwPmyAkH1Ev. I hope that this is the desired functionality.

  Hi Marin,
  
  Thanks so much for your response.
  
  Attached is the picture of my Radschedule with a combobox on top to let an user select an individual name which is fed by RecordNum.  This value is an integer, and I got this from Session, whenever a user selects a name from the drop-down box, I capture the RecordNum of that person.
  
  I pasted the code of my default.aspx page here with your suggestion.  But it is still not working, alert message kept showing.
  I don't know what I did wrong.
  
  Please help!
  
  Thanks,
  
  Tiffany Phan

  Hello Tiffany,

  This code runs as expected on my end. You can find my test page attached and here is a video from this test: http://screencast.com/t/w3g1oz8iVr.

  The changes I had to make were:

  1. create a sample scheduler so that I can run your code
  2. hardcode a value to the recnum variable, since I do not have your custom logic

  This leads me to believe that the most probable cause for this behavior is that the recnum variable is still null or undefined and thus the issue originates in the logic that populates it.

  What I can suggest at this point to either debug this issue on your end, or open a support ticket and send us a sample, runnable project that isolates this case so that we can debug it locally and pinpoint the cause.

  
  
  All the best,

  Hi Marin,
  
  Finally, it works!
  
  The reason is that I got wrong format for Session("RecordNum") in my client side. 
  When I found the syntax Session in Javascript code, it went smoothly.
  
  Thank you so much,  I appreciate!
