ClientEvents-OnResponseEnd not working properly

[shinu rag]

hi...

when using RadAjaxManager, its OnResponseEnd event not working properly...
here everything working when i put one alert('ss') before calling ajaxrequest...
but when i comment the alert('ss') onresponseEnd doesn't show the content from UpdatedControl...

please check my code..

here it is...

js code

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>


<telerik:RadScriptManager ID="RadScriptManager2" Runat="server">
</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="ajaxManager_AjaxRequest"
 ClientEvents-OnResponseEnd="NewEncounterResponseEnd">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="HiddenField1" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>


                    <asp:Button ID="btnOK" runat="server" Text="OK"
                        OnClientClick="returnToParentNewEncounter('Save');"/>
                    <asp:HiddenField ID="HiddenField1" runat="server" />

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
 <script type="text/javascript">

function returnToParentNewEncounter(btn)
{

   if(btn=='Save')
    {
       //  alert('ss');
         var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("NewEncounter");
    }
}

function NewEncounterResponseEnd(sender, args)
{
    var oArg = new Object();
    var oWnd = GetRadWindowNewEncounter();

    var hidden_input = document.getElementById("<%= HiddenField1.ClientID %>").value;
    alert(hidden_input);
}
</script>

</telerik:RadCodeBlock>

c# code

public void ajaxManager_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
   HiddenField1.Value = "Invalid Patient ID";
}

i used both RadCodeBlock and RadScriptBlock....
but still have the problem.....

You need to prevent the regular callback that would happen because of the button click. Otherwise two callbacks will happen and your field will not be updated properly.
Try this code:

<asp:Button ID="btnOK" runat="server" Text="OK"
OnClientClick=" returnToParentNewEncounter('Save'); return false; "/>

The alert can slows things down and reverses the calls, or one of them not happen at all.

Hi Edward.. thanks for ur reply....
its working properly when we use 'return false.' with onclientclick...
but in the following situation how can i prevent the button regular callback..
here i add two controls.. one text box and one radcombobox...
combobox have selected index changed event.. i need to execute this event, even the required filed validator is on or not... so i'm  using the validation group.... 

here it all working except getting data from hidden field....
