How to access Master page members(like properties) from child page.

To Access public members like Property of a Master Page in Child Page we need to specify @MasterType directive with virtualpath attribute pointing to MasterPage path. i.e Use the @MasterType directive to set the strong type for the master page, as accessed through the Master property. MasterPage: public string masterVariable = "interviews.dotnetthread.com". .... Child Page: <%@ Page Language="C#" MasterPageFile="~/master/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="menu_master_Default" Title="Untitled Page" %> <%@ MasterType VirtualPath="~/master/MasterPage.master" %> Then in Page_Load we can access as below sting childVar = this.Master.masterVariable;
