  Requirements
  RadControls version	Telerik.Web.UI 2009.3.1103.0+
  .NET version	NET 2.x/3.x
  Visual Studio version	2005/2008
  programming language	C# and VB
  browser support	all browsers supported by RadControls

  
  PROJECT DESCRIPTION
  The attached example demonstrates how to dynamically create RadDock objects and save their state in a DataBase. It is based on the my portal online demo for the RadDock.
  
  The RadDock controls are added to a "hidden" (placed inside a <div> element with display:none) UpdatePanel and after that, with a client-script registered from the server, moved to the respective RadDockZone.
  
  

  <div style="display: none">

  Hidden UpdatePanel, which is used to receive the new dock controls. We will move them with script to the desired initial dock zone.

  <asp:UpdatePanel runat="server" ID="UpdatePanel1">

  <Triggers>

  <asp:AsyncPostBackTrigger ControlID="ButtonAddDock" EventName="Click" />

  </Triggers>

  </asp:UpdatePanel>

  </div>

  
  This way when the user interacts with the RadDock control only the content of the UpdatePanel is updated by the AJAX request, and the performance of the page is increased.

  I need this for Radgrid, but i got an error
  

  Error de servidor en la aplicación '/'.

  ---

  No se puede registrar UpdatePanel con el id. 'UpdatePanel1' porque no se registró con ScriptManager. Este problema puede surgir si el control UpdatePanel se quitó del árbol de controles y se volvió a agregar más tarde, lo que no está permitido.
  Nombre del parámetro: updatePanel

  Hello Julieta,
  
  Please note that this Code Library article demonstrates a RadDock functionality and it is not concerned with the RadGrid control. The reported problem may be caused by nested UpdatePanels, so I would recommend checking this article and trying to set the UpdateMode of the update panels to Conditional. I have found also a forum thread that could help you solve the problem at hand.
  
  Note that at the current state of affairs I am mostly guessing as to what your setup is. If you are still experiencing difficulties please prepare and send us a sample, runnable project that displays your issue so that we can examine it locally and provide a more to the point answer.
  
  Kind regards,
  Slav
