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.
Source Code (MasterPage):
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<%@ Register Assembly ="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="pm" %>

<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
<style type="text/css">
.style1
{

}
.style2

</pm:ModalPopupExtender>
<asp:Button ID="Button8" runat="server" Text="Log In" style="display:none" />
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Panel ID="Panel1" runat="server" Width="500px">

<td>

</tr>
</table>
</asp:Panel>

<td>

</tr>
</table>
</div>
</form>
</body>
</html>
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" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<table class="style1">
<tr>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
</td>
<td colspan="2">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<br />
<table class="style1">
<tr>
<td>
<asp:Button ID="Button9" runat="server" onclick="Button9_Click" Text="Button" />
<asp:ScriptManager ID="ScriptManager2" runat="server">
</asp:ScriptManager>
</td>
<td>
</td>
</tr>
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</td>
<td>
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
</td>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
<tr>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</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):
"The COntrol with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."
Then I add a ScriptManager on Default3.aspx page within UpdatePanel1.
Then Again Run Default3.aspx:
Error: Only one instance of a ScriptManager can be added to the page..
This is the Problem...................
Please solve this problem whereas I use multiple ScriptManager in another page using MasterPage (where already use ScriptManager).推荐答案
You only need one ScriptManager tag. Do not place it so low in your page. The best position for it is right after the opening for tag in your Master Page.

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" EnableScriptGlobalization="true"
EnableScriptLocalization="true">
</asp:ScriptManager>
