Im trying to implement a 'numericupdown' AJAX control within the gridview cell of my ASP.NET website.I have dragged and dropped a 'scriptManager' from the AJAX Extentions part of the toolbox.Currently when i run my website (which is hosted locally) i am getting the following error:\[code\]Server Error in '/' Application.Parser ErrorDescription: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Unknown server tag 'ScriptManager1:numericupdownextender'.Source Error: Line 85: </asp:GridView>Line 86: Line 87: <ScriptManager1:numericupdownextender Line 88: id="NumericUpDownExtender1" Line 89: runat="server" \[/code\]I have done some research and it seems this is a common issue but having never dealt with AJAX before Im stuck with how to solve it. Here is the server side code of my website:\[code\]<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"CodeBehind="Default.aspx.cs" Inherits="ViewCDs._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">\[/code\] Welcome to 'CD Collection'.
