    Hello, I recieved strange problem and everything Ive tried to solve it - failed so hope sombody can give me a hand. The problem is that I Can not FindControl("ControlID") when the control is int contentPage. The Code is really simple:

    <%@ Page Language="VB" MasterPageFile="~/Main.master" Title="Untitled Page" %>

    <script runat="server">

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
            Dim myControl1 As Control = me.Page.FindControl("TextBox1")
            If (Not myControl1 Is Nothing) Then
                ' Get control's parent.
                Dim myControl2 As Control = myControl1.Parent
                TextBox1.Text = "Parent of the text box is : " & myControl2.ID
                TextBox1.Text = "Control not found....."
            End If
        End Sub

    <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
        <asp:TextBox ID="TextBox1" runat="server" Width="579px"></asp:TextBox>


    Any Idea is welcome

    I had the same problem.  The syntax I used was similar to your solution:
