    [CLOSED] Different behaviors in DirectEvent between UserControlLoader and UserControl

            </Buttons>

    </Items>
</ext:Window>

    ascx.cs
    using System;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Ext.Net;


public partial class Test31a : UserControl {
    protected void Page_Load( object sender, EventArgs e ) {
        if( !X.IsAjaxRequest )
            TW.Show();
    }


    protected void OnAdd( object sender, DirectEventArgs e ) {
        var items = MS.SelectedItems;
        int len = items.Count;
        X.Msg.Alert( "Items", len.ToString() );
    }
}
    aspx
    <%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>


<script runat="server">
    protected void Page_Load( object sender, EventArgs e ) {
        var ctl = Page.LoadControl( "Test31a.ascx" );
        ctl.ID  = "TaskUC" + 1.ToString();
        Page.Controls.Add( ctl );
    }
</script>


<!DOCTYPE html>
<html>
<head id="Head1" runat="server">
    <title>Test31a</title>
</head>
<body>
    <form id="Form1" runat="server">
        <ext:ResourceManager ID="ResourceManager1" runat="server" ViewStateMode="Enabled" ScriptMode="Debug" SourceFormatting="true" />


        <ext:Viewport ID="vp" runat="server">
        </ext:Viewport>


    </form>
</body>
</html>
    This version does trap in OnAdd and len does seem to contain the count of selected items.

    However, this slight change in the aspx Page_Load to the following does not.
        protected void Page_Load( object sender, EventArgs e ) {
        var ctl = new UserControlLoader( new UserControlLoader.Config() { Path = "Test31a.ascx" } );
        ctl.UserControlID = "TaskUC" + 1.ToString();
        vp.Bin.Add( ctl );
    }

    I should note also that both fail to display the alert.

    Hi @michaeld,

    Running your initial test case (without a UserControlLoader) I can state that it is not true for me:

    It is zero for me. And, as far as I can see, it should be zero, because you add a Window in the Page.Controls. It means it is not falling into the <form>. With this:
    this.Form.Controls.Add( ctl );
    the selected items get submitted.

    As for a UserControlLoader. It seems to be working for me without any changes.

    You should call the Show method.
    X.Msg.Alert("Items", len.ToString()).Show();

    This strategy was at the advice of vladimir in http://forums.ext.net/showthread.php...endering/page2

    He may not have considered the post-back consequences or I may have misunderstood his direction. I'll consider instead your suggestion of this in the future:

    Ultimately this should address my non-sample code that shared the same problem.

    This was what I was trying to establish.

    Sorry. My intuition keeps failing me that the Alert is returning an object; that it's not a method. I often manage to forget the Show() part. Thanks for the reminder.

    Well, he didn't mean adding direct to Page.Controls. So, if you need to get the controls submitted, please add them to Form. A Form is inside a page. So, it doesn't conflicts with the Vladimir's suggestion.

    The same happens for me as well sometimes:)
