Hi

I would like to use contentpage controls from master page. the senario is like this...

I have project with master page and master page has a webusercontrol. webusercontrol has button. when webusercontrol button is clicked. the content page's text box should have a focus on it. Button is wrapped in updated panel as its ajax enabled site.

I googled the problem but not offered much help

thanks in anticipation!!!

Master Page

<%@ Master Language="VB" AutoEventWireup="false" Codebehind="MainMaster.master.vb"
    Inherits="Focus.MainMaster" %>
<%@ Register Src="WebUserControl1.ascx" TagName="WebUserControl1" TagPrefix="uc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
    <form id="form1" runat="server">
     <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <uc1:WebUserControl1 ID="WebUserControl1_1" runat="server"></uc1:WebUserControl1>
        <div>
            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            
               <ContentTemplate>
                    <asp:Button ID="btnMasterPageButton" runat="server" Text="MasterPageButton" />
                <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
                </asp:ContentPlaceHolder>
                </ContentTemplate>
               
          </asp:UpdatePanel>
        </div>
    </form>
</body>
</html>

Generally speaking, trying to access the content page from the master page is a pretty backwards way of doing something. If you have multiple content pages are they all going to implement this behavior? It would be easier, and make more sense, to put the user control into the content pages rather than putting the user control into the master page. This way you can include it only in the pages that would need it since most like not every content page would use it. Then you can access the content page through the "Page" property of the user control.
