Here is a code snippet that I came up with to help all of you out there.

Dim _myControl As WebControl = Master.FindControl("ContentPlaceHolder1").FindControl(ControlToEnable)
_myControl.Visible = True

.Parent.FindControl("fldNews")

was enough (notice 'parent').

I always used an recursive function, but that dind't work either... after alot of debugging in that function, I found out the container was wrong and I needed it's parent.

Thanks guys

I think you need to add a statement in the ASPX page which contains the user control.

Just after the <%page> directive, add this:
<%@master virtualpath="~/masterpage.master">

Then you can access the controls that located in master page.

Problem Findcontrol and Masterpage

Eriksk — Sun, 02 Jul 2006 13:05:16 GMT

Hi all,

I've got a problem with the findcontrol function. I use this function in a usercontrol to retrieve a value from an hidden field in the page (Dim iTypeOfNews As Integer = Convert.ToInt16(CType(Page.FindControl("fldNews"), HiddenField).Value)). It all worked fine, untill I put that page in a contenplaceholder in a masterpage. The function can't find the hiddenfield anymore.
The code:

<%@ Page Language="VB" MasterPageFile="~/Main.master" Trace="true"  AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" title="Untitled Page" %>

<%@ Register Src="UserControls/News.ascx" TagName="News" TagPrefix="uc1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cphMain" Runat="Server">
    <asp:HiddenField ID="fldNews" runat="server" Value="1" />
    <uc1:News ID="News1" runat="server" />
</asp:Content>

Has someone a solution?

Thanks in advance.
Regards,
Erik
