I have the datefilter in my dynamic data app where I want to make use of the Ajax Calender Extender. I get the error :-
Only one instance of a ScriptManager can be added to the page
I understand that the master page already has the script manager. I tried using "Asp:ScriptManagerProxy" and didn't work.
Following is my DateFilter.ascx. Any help will be appreciated:-
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DateFilter.ascx.cs" Inherits="TestApp.DynamicData.Filters.DateFilter" %>
<%--<Asp:ScriptManagerProxy runat="server" ID="proxy"/>--%>
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajaxToolkit:ToolkitScriptManager>
<asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox>
<asp:TextBox ID="txtEndDate" runat="server"></asp:TextBox>
<ajaxToolkit:CalendarExtender
ID="CalendarExtender1"
TargetControlID="txtStartDate"
runat="server" />
<ajaxToolkit:CalendarExtender
ID="CalendarExtender2"
TargetControlID="txtEndDate"
runat="server" />
Below is the site.master for my dynamic data app
<%@ Master Language="C#" CodeBehind="Site.master.cs" Inherits="TestApp.Site" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<asp:ContentPlaceHolder id="head" runat="server">

</head>
<body>
<h1 class="DDMainHeader">Test App</h1>
<div class="DDNavigation">
<%-- <a runat="server" href="~/"><img alt="Back to home page" runat="server" src="DynamicData/Content/Images/back.gif" />Back to home page</a>--%>
</div>
<form id="form1" runat="server">
<div>

I think if your are using ToolkitScriptManager in your master page you don't need to place anything in your ascx
