Good Day,
Please advise on how to fix this Scriptmanager error '
Only one instance of a ScriptManager can be added to the page.'
I used the template within Visual studio to create ASPNet Web application. On one of the page I replaced the content with
<asp:ScriptManager runat="server" />
<crm:CrmDataSource ID="Contacts" runat="server" />
<crm:CrmEntityFormView DataSourceID="Contacts" EntityName="contact" SavedQueryName="ContactForm" runat="server" />
.....But I want the contact Form to inherit design from the Master page, so I had a final code like this..........
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CRMAPP._Default" %>
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<asp:ScriptManager runat="server" />
<crm:CrmDataSource ID="Contacts" runat="server" />
<crm:CrmEntityFormView DataSourceID="Contacts" EntityName="contact" SavedQueryName="Create Contact Web Form" runat="server" />
</asp:Content>
But I am now getting this error message
Only one instance of a ScriptManager can be added to the page.
