How can I reference ContentPlaceHolder Control inside the WebSplitter template?
posted
I have a Master Page and a content page named "Default.aspx".
-In the Master Page, It contains a WebSplitter. The left SlitterPane contains links and the right SplitterPane contains a ContentPlaceHolder.
-In the Default.aspx, it's a content page and referencing Master Page, so this content page is actually the child of ContentPlaceHolder of the Master Page.
-When ran the Default.aspx, I tried to reference the ContentPlaceHolder in the Page Load method of Default.aspx.vb , but it couldn't find the ContentPlaceHolder control. Here's my referencing code in  the Default.aspx.vb: 
          
                    Dim content As ContentPlaceHolder
                    content = Page.Master.FindControl("ContentPlaceHolder1")

-The code work if I put the ContentPlaceHolder outside the WebSplitter in the Master Page.

-----------Here's my Master Page Design Code------------:

<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<%@ Register Assembly="Infragistics2.Web.v8.2, Version=8.2.20082.1000, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
Namespace="Infragistics.Web.UI.LayoutControls" TagPrefix="ig" %>

<head runat="server">

</head>

<body style=" margin:0px; padding:0px; height:100%; width:100%; margin-bottom: 1px; margin-right:1px;">
     <form id="form1" runat="server" style="height:100%;width:100%" >

          <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

          <ig:WebSplitter ID="WebSplitter1" style="height:100%; width:100%; " runat="server">
               <panes>
                    <ig:SplitterPane runat="server" Size="15%" CollapsedDirection="PreviousPane">
                         <Template>Left Navigation</Template>
                    </ig:SplitterPane>
                    <ig:SplitterPane runat="server">
                           <Template>
                                <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
                                     Content Page Inside the ContentPlaceHolder1
                                </asp:contentplaceholder>
                           </Template>
                    </ig:SplitterPane>
            </panes>
         </ig:WebSplitter>
      </form>
</body>
</html>

--------Here's my Default.aspx design code---------:

<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" title="Untitled Page" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
     Welcome To My Page!
</asp:Content>

----------Here's my Page Load method in the Default.aspx.vb-------:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
     Dim content As ContentPlaceHolder
     content = Page.Master.FindControl("ContentPlaceHolder1")
End Sub

    I found a solution:

    In Page Load method in the Default.aspx.vb, I have the following code, and I can find the ContentPlaceHolder control.

    Here's the code:

    Dim WebSplitter As Infragistics.Web.UI.LayoutControls.WebSplitter
    Dim SplitterPane As Infragistics.Web.UI.LayoutControls.SplitterPane
    Dim TemplateContainer As Infragistics.Web.UI.TemplateContainer
    Dim contentPlaceHolder As ContentPlaceHolder

    WebSplitter = Page.Master.FindControl("WebSplitter1")
    SplitterPane = WebSplitter.Panes(1)
    TemplateContainer = SplitterPane.Controls(0)
    contentPlaceHolder = TemplateContainer.FindControl(    "ContentPlaceHolder1")
