Hi,
I used following code in my page.

<%

 

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

<

 

 

form id="form1" runat="server">

 

 

 

<telerik:RadScriptManager ID="RadScriptManagerCP" runat="server">

 

 

 

</telerik:RadScriptManager>

 

 

 

<table cellpadding="0" cellspacing="0" border="0">

 

 

 

<tr>

 

 

 

<td>

 

Est Prod Date

 

&nbsp;</td>

 

 

 

<td style="padding-right: 20px">

 

 

 

<table border="0" cellpadding="0" cellspacing="0">

 

 

 

<tr>

 

 

 

<td>

 

 

 

<asp:TextBox ID="prodDT" runat="server"></asp:TextBox></td>

 

 

 

<td>

 

 

 

<asp:Panel ID="panelProdDT" runat="server">

 

 

 

</asp:Panel>

 

 

 

</td>

 

 

 

</tr>

 

 

 

</table>

 

 

 

</td>

 

 

 

</tr>

 

 

 

<tr><td><asp:TextBox runat="server" ID="txt" TextMode="MultiLine"></asp:TextBox></td>

 

 

 

<td><telerik:RadSpell ID="spell1" Runat="server" ControlsToCheck="txt" IsClientID="true" ButtonText="Spell Check"/></td></tr>

 

 

 

</table>

 

 

 

 

</form>

Now the page is throwing error.
