Thanks. I eventually came up wqith something similar, though not as elegant (I'm not that familiar with JQuery yet). But I did get what I wanted.

I"m assuming the JQuery lines are literals created using $find('<%=dlgMessage.ClientID%>') style syntax - an you show me the original source lines please?

Actually, the javascript function is actual code. (no <%...%>).  The aspx lines are:

<%@ Register src="uc/ucjDlgMsg.ascx" tagname="ucDlgMsg" tagprefix="ucClientDlg" %>
...
<ucClientDlg:ucDlgMsg ID="ctlDlgMsg" runat="server" />

and the actual user control is:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucjDlgMsg.ascx.cs" Inherits="WebGen.ucjDlgMsg" %>
<%@ Register TagPrefix="cc1" Namespace="Infragistics.Web.UI.LayoutControls" Assembly="Infragistics35.Web.v9.2, Version=9.2.20092.2056, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" %>
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
</asp:ScriptManagerProxy>

Hi Greg,

I wrote a sample for you which create child elements in dialog dynamically. You can do similar at any time. Below is ClientEvents.Loaded was used.

<script type="text/javascript">
function clickMe()
{
 var field = $get('dynamicFieldID');
 var message = 'Button click';
 if(field)
  message += ' Field:' + field.value;
 alert(message);
}
function createChildren(dialog, evtArgs)
{
 var div = dialog.get_contentPane().getBody();
 var button = document.createElement('INPUT');
 button.type = 'button';
 button.value = 'Dynamic Button';
 button.onclick = clickMe;
 div.appendChild(button);
 var field = document.createElement('INPUT');
 field.value = 'enter value';
 field.id = 'dynamicFieldID';
 div.appendChild(field);
}
</script>
<ig:WebDialogWindow ID="WebDialogWindow1" runat="server" Height="200px" Width="200px" InitialLocation="Centered">
 <ClientEvents Loaded="createChildren" />
</ig:WebDialogWindow>

Hi Victor,

Thanks for the sample.  Most of my production code is server-centric, but I am slowly evolving it into a more client-centric architecture.  Your sample helps.

By the way, my profile is set up to receive emails, but I am getting any emails.  Do you perhaps know what I need to do?
