  Problem Findcontrol and Masterpage

  Jul 02, 2006 01:05 PM|LINK

  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

  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.

  Me.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

  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
  

  master page find control
