ASP.NET has internal property for each page 'Master'. From usercontrol you can travese the stack backwards to Usercontrols parent > Page > Master. If the control in master page is outside any contentplace holders, you can get the control using FindControl method. If it is inside any content place holders, you have to traverse to the content place holder and then you can find the control. The example is below.
MASTER
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="lblVal" runat="server" Text="MasterLabel"></asp:Label>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
CONTENT PAGE
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<test:uc ID="test" runat="server" />
</asp:Content>
USER CONTROL
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
USERCONTROL CODE BEHIND
protected void Page_Load(object sender, EventArgs e)
{
MasterPage mstr = this.Parent.Page.Master as MasterPage;
Label1.Text = (mstr.FindControl("lblVal") as Label).Text;
}
In my case the Label in master page is outside content page.
