How to use another/multiple ScriptManager in other page using MasterPage which MasterPage has a ScriptManager?
Design Page (MasterPage.master):here, I use a ScriptManager, Panel (black colored) and a button. And also use Ajax ModalPopupExtender1.

Code View(MasterPage):public partial class MasterPage : System.Web.UI.MasterPage
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
ModalPopupExtender1.Show();
}
}
Design Part (Default3.aspx)here I use a UpdatePanel. Does not use any extra ScriptManager.
Source View (Default3.aspx)<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" Title="Untitled Page" %>

<tr>

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

</table>
</asp:Content>
Code View (Default3.aspx.cs)public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button9_Click(object sender, EventArgs e)
{
Label1.Text = "Hello";
}
}
Run (Show Error)
Then I add a ScriptManager on Default3.aspx page.Design Part (Default3.aspx): Modified:
Then Again Run Default3.aspx:Error:
This is the Problem...................
Please solve this problem whereas I use multiple ScriptManager in another page using MasterPage (where already use ScriptManager).
