Hi,

I guess you don't recreate a control during DirectEvent and trying to access that control.

How do you create 'ctl00$Child1$btnForgottenPassWord' control?

Can you provide a full sample to reproduce?

                    </ext:TextField>
                    <asp:dropdownlist id="LAST_NAME" runat="server" visible="False" />
                </asp:tablecell>
                <asp:tablecell>
                &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                </asp:tablecell>
                <asp:tablecell>

Well, Ext.Net controls works fine with Asp.Net controls.

Just remember that Asp.Net controls requires hard post back (not ajax which is produced by DirectEvent).

So, the following example works fine.

Example

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

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

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            this.Label1.Text = this.TextField1.Text;
        }
    }
</script>

    <title>Ext.Net Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        asp:Label:&nbsp;&nbsp;&nbsp;
        <asp:Label ID="Label1" runat="server" />
        <br />
        <ext:TextField ID="TextField1" runat="server" FieldLabel="ext:TextField" />
        <ext:Button runat="server" Text="Postback" AutoPostBack="true" />
    </form>
</body>
</html>

Also the .PostBackUrl and OnDirectClick are incompatible things.
