Hello.
my updatepanel won't work in content page, that mean page_load and click event of the button dose not fire but page_preinit fires.
whenever i use an aspx page without masterpage everything works correctly.

Code :

Content Page :

HTML Code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Frontend.master" AutoEventWireup="true" CodeFile="RegEstate.aspx.cs" Inherits="RegEstate" %>

<asp:Content ID="Content1" ContentPlaceHolderID="cpMC" runat="Server">
    <section class="wrapper style2">
        <div class="container">
            <header class="major">
                <asp:Button ID="btn" Text="click" runat="server" OnClick="btn_Click"/>
                <asp:UpdatePanel runat="server">
                    <ContentTemplate>
                        <asp:TextBox ID="txtBox" runat="server" />
                    </ContentTemplate>
                    <Triggers>
                        <asp:AsyncPostBackTrigger ControlID="btn" EventName="Click" />
                    </Triggers>
                </asp:UpdatePanel>
            </header>
        </div>
    </section>
</asp:Content>

MasterPage:

HTML Code:

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Frontend.master.cs" Inherits="Frontend" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Arcana by HTML5 UP</title>
    <meta charset="utf-8" />

</head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="SM" runat="server" />
</form>

Thank you

Hi there,

Maybe this helps? https://msdn.microsoft.com/en-us/lib...vs.140%29.aspx

The master page needs the ScriptManager control.

Cheers,

Hello , Thanks for your respond , i wish you were my teacher ;)
My problem has been solved by removing nested <form> element in the master page

i didn't pay attention to the extra <form> element
