    [CLOSED] I wish get the parent ID in Code Behind

    Hi!

    Hi! I create a window in code behind (test23.aspx code) and I´m loading a aspx page (test24.aspx) within of window.
    I wish, in a codebehind procedure of test24.aspx, get the ID of window that contains the test24.aspx.

    Follow a little sample! In procedure ShowWindowParentID of test14.aspx, I wish get the window ID.

    Test23.aspx

    Hi,

    There is no way to get it on server side. But it's possible to get an id on client side and send it as a DirectEvent extra parameter.

    Is there any example I can follow?

    Well, via DirectEvent ExtraParams.
    <ext:Parameter Name="id" Value="parentAutoLoadControl.id" Mode="Raw" />

    Hi Daniil

    I'm sorry, but I'm doing something wrong!

    I insert the extraparam tag in directevent of button... but I get error when the page test24.aspx is loaded.

    Runtime Error in Microsoft JScript: 'parentAutoLoadControl' is not defined.

    Follow my changes in Test24.aspx... Test23.aspx is the same...
    <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test24.aspx.vb" Inherits="WebApplication3.Test24" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

        Dim mb As New Ext.Net.MessageBox
        mb.Alert("ParentID", "I wish show the parent window ID here!")
        mb.Show()
    End Sub

    Hi Daniil!

    I did what I wanted, using your tip!

    I set to a ext:hidden the ID in AfterRender event...

    thanks a lot

        <ext:Hidden runat="server" ID="txtWindowCfgID" Text="">
        <Listeners>
            <AfterRender Handler="this.setValue(parentAutoLoadControl.id);"  Delay="100" />
        </Listeners>
    </ext:Hidden>

    Good point.

    Though I was unable to reproduce this error:
    Runtime Error in Microsoft JScript: 'parentAutoLoadControl' is not defined.
    Here is my test case.

    Example Parent Page
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

    <title>Ext.NET v2 Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:Window 
            ID="Window1" 
            runat="server" 
            Width="300" 
            Height="300">
            <Loader runat="server" Mode="Frame" Url="Test.aspx">
                <LoadMask ShowMask="true" />
            </Loader>
        </ext:Window>
    </form>
</body>
</html>
    Example Child Page
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void GetID(object sender, DirectEventArgs e)
    {
        X.Msg.Alert("ID", e.ExtraParams["id"]).Show();
    }
</script>
