RadAjaxManager: problem on second call back

[Sathish]

Hi,

I am trying to implement radajax manager. Here is the structure of my program

Global_masterpage
Module_masterpage
Content page

the rad script manager is in global masterpage and module masterpage has one scriptmanagerproxy for a composite script and the module masterpage has the radajaxloading panel to show ajax progress.

now in the content page, i got the code below. (extracted from a big page for testing and locating the problem). i'm trying to show the advanced search panel (pnlSearchCriteria) when you click on the lnkShowAdvancedSearch and Hide it from lnkHideAdvancedSearch (which is inside pnlSearchCriteria) The first time, the control behaves as expected. the next time i click on lnkshowadvancedsearch button, the pnlsearchcriteria does not show up and the progress area (radajaxloadingpanel) shiows activity and goes on forever. in the project configuration wizard i have all of them enabled.


here is the aspx code and followed by the vb code

<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/MasterPage.master"
    CodeBehind="WebForm2.aspx.vb" Inherits="ERP.OM.WebForm2" %>

Hi Sathish,

RadAjaxManager should go into the Global_masterpage. For the content page, you need to use RadAjaxManagerProxy. For more info:
