    [CLOSED] DirectMethod in a MasterPage

    Hi,
    When I am trying to call Direct Method declared in a MasterPage I get the following error :

    The ajax instance method 'TEST' is absent!

    Here's the code. Try calling DM.Test()

    Page.aspx: 
    <%@ Page Title="" Language="C#" MasterPageFile="~/system/templates/browser.master" AutoEventWireup="true" CodeBehind="accident.aspx.cs" Inherits="Web.ui.browsers.accident" %>
<%@ MasterType VirtualPath="~/system/templates/browser.master" %>
    MasterPage.aspx
    using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Ext.Net;
namespace Web.ui.browsers
{
    public partial class accident : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
           
        }


    }
}
    MasterPage
    <%@ Master Language="C#" MasterPageFile="~/system/templates/content.master" AutoEventWireup="true" CodeBehind="browser.master.cs" Inherits="Web.system.templates.browser" %>


<asp:Content ID="Content1" ContentPlaceHolderID="innerhead" runat="server">
    <script src="../../global/js/browser.js"></script>
    <style type="text/css">
        .x-grid-row-summary .x-grid-cell-inner {
            font-weight: bold;
            font-size: 11px;
            background-color : #f1f2f4;
        } 
    </style>


</asp:Content>


<asp:Content ID="Content2" ContentPlaceHolderID="innercontent" runat="server">

namespace Web.system.templates

    [DirectMethodProxyID(IDMode = DirectMethodProxyIDMode.None)]
    public partial class browser : System.Web.UI.MasterPage
    {


        protected void Page_Load(object sender, EventArgs e)
        {
        }




        [DirectMethod]
        public string TEST()
        {


            return "a";
        }


        
    }
}

    I don't see your ResourceManager. Also, why do you use DM namespace for DirectMethods? Also, it's better to use special wildcard #{DirectMethods}. I've tried with the following sample and it works:

    MasterPage.aspx
    <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="Ext.Net.Examples.Site1" %>

<script runat="server">
    [DirectMethod]
    public void DoSomething()
    {
        X.Msg.Notify("Time", DateTime.Now.ToLongTimeString()).Show();
    }
</script>

<!DOCTYPE html>
 
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Ext.NET Example</title>
    <asp:ContentPlaceHolder ID="head" runat="server" />
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
 
        <asp:ContentPlaceHolder ID="MainContent" runat="server" />
    </form>
</body>
</html>
    MasterPage.aspx.cs
    [DirectMethodProxyID(IDMode = DirectMethodProxyIDMode.None)]
public partial class Site1 : System.Web.UI.MasterPage
{
	protected void Page_Load(object sender, EventArgs e)
	{

	}
}
    Page:
    <%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Ext.Net.Examples.WebForm1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <ext:Button runat="server" Text="Submit" OnClientClick="#{DirectMethods}.DoSomething();" />
</asp:Content>

    Hi,

    Be careful with #{DirectMethods}. It might not work in some complex scenarios.

    Hi Baidaly,
    I missed the the resource manager. Please test using the code I sent with the following MasterPage. It does'nt work.
    Also, I user DirectMethodNamespace to keep my DirectMethods organised. I don't see why that should be an issue. There is something else I am missing, which I cannot figure. Can you run my exactly my sample with the folliwng master page.

    <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="browser.master.cs" Inherits="Web.system.templates.browser" %>
 
 
<asp:Content ID="Content1" ContentPlaceHolderID="innerhead" runat="server">
    <script src="../../global/js/browser.js"></script>
    <style type="text/css">
        .x-grid-row-summary .x-grid-cell-inner {
            font-weight: bold;
            font-size: 11px;
            background-color : #f1f2f4;
        } 
    </style>
 
 
</asp:Content>
 
 
<asp:Content ID="Content2" ContentPlaceHolderID="innercontent" runat="server">
<ext:ResourceManager ID="extrm" runat="server" DirectMethodNamespace="DM">
        </ext:ResourceManager>
<ext:Viewport runat="server" ID="browserViewport" Layout="FitLayout">
</ext:Viewport>
</asp:Content>

    I am getting this exception: Content controls are allowed only in content page that references a master page.

    Indeed, I see <asp:Content> in the MasterPage, but it seems has not reference to another MasterPage.

    Hi Daniil,
    My mistake. I will put up everything together in one zip file and send it to you.

    Thanks,

    If possible, it would be better to post the required things here wrapping in [CODE] tags.

    To avoid many code snippets, you can place code behind directly on ASPX pages by wrapping in
    <script runat="server">
    // code behind stuff
</script>

    Hi Daniil,
    Please check the following:

    I observed that, having if I have resourcemanager in text.aspx page, everything works well, but if I have resource manager in base.master, DirectMethod registers on client side, but throws the exception on execution. Please check for yourself by running test.aspx. Do the following :

    1) Run test.aspx
    2) Call DM.Test() from the JS console.

    base.MASTER
    <%@ Master Language="C#" AutoEventWireup="true" %>

    Try to add IDMode attribute:

    <script runat="server">
    [DirectMethod(IDMode = DirectMethodProxyIDMode.ID)]
    public string TEST()
    {
        Ext.Net.MultiSelect t = new MultiSelect();
        Ext.Net.Panel p = new Ext.Net.Panel();
        p.Add(t);
        return p.ToScript();
    }
</script>
