Can not find control in RadAjaxPanel for content page

[Lubna Ansari]

Hi,

I am using a master content page.  I am able to find the controls on content page which are outside AjaxPanel but not which are inside.

<%

@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" MasterPageFile="~/MasterPage.master" %>

 

<%

@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

 

<

 

asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server" ID="Cnt1">

 

<

 

telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePageMethods="true"></telerik:RadScriptManager>

 

 

 

<asp:TextBox ID="txtTest" runat="server" Text="abc">

 

 

</asp:TextBox>

 

 

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="LoadingPanel1">

 

 

<telerik:RadTextBox ID="txtRad" runat="server" Text="xyz"></telerik:RadTextBox>

 

 

</telerik:RadAjaxPanel>
<

 

script type="text/javascript">

 

alert(document.getElementById(

"<%=txtRad.ClientID%>").value);

 

 

</script>

 

 

 

</asp:Content>


I am getting error

 

 "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). "

Below is my Master Page code

 

<%

@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

 

<%

@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

How to find the control in RadAjaxPanel??

[robertw102]

Place your script block in a RadScriptBlock control.

I hope that helps.
