My problem is :

I have a .aspx page where I use a ScriptManager and a UpdatePanel.

In the update panel I generate controls based on user interactions.
My problem is this : when I add dynamically the CustomControl (.ascx page ) in the UpdatePanel ( the CustomControl has a ScriptManagerProxy ) the AsynchronousPostBack for the .ascx page doesn't work, at all.

The fact that this is the first time I try this is not a bonus :D .

code for adding the user controls :

Control myControl = Page.LoadControl("NewUser.ascx");
            myControl.ID = "NewUser";

placeHolder is in the UpdatePanel.

and all the Ajax calls inside the CustomControl are in the UpdatePanel of the CustomControls like this :

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
     <asp:TextBox runat="server" ID="txt_Username" OnTextChanged="txt_Username_TextChanged" />

So I see the dynamically added CustomControl in the page but the AsynchronousPostBack is not called for the CustomControl , any ideas ? Help ? :)
