In previous posts I explained many articles relating to asp.net, gridview, SQL Server, JQuery, JavaScript and etc. Now I will explain how to access master page controls from child page or content page in asp.net.
To
get master page control values in content page first write the following code
in master page like this
MasterPage.Master
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Master Page with Controls</title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1"
runat="server">
<div>
MasterPage Label:
<asp:Label ID="lblMaster"
runat="server"
Text="Sample
master Page label Control"/>
MasterPage Textbox:
<td><asp:textbox ID="txtMaster"
runat="server"
Text="Sample
Master Page Textbox Control"/>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
|
After
that write the code in Content Page Default.aspx
will be like this
<%@ Page Language="C#"
AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default"
MasterPageFile="~/MasterPage.master"
%>
<asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<b>Content Page Label Value:</b>
<asp:Label ID="lblContent"
runat="server"/>
<br />
<b>Content Page Textbox Value:</b>
<asp:Textbox ID="txtContent"
runat="server"/>
</asp:Content>
|
After
completion of Default.aspx page add
following namespaces in codebehind
C#
Code
using System;
using System.Web.UI.WebControls;
|
Now
add following code in code behind
protected void
Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
Label masterlbl = (Label)Master.FindControl("lblMaster");
TextBox mastertxt = (TextBox)
Master.FindControl("txtMaster");
lblContent.Text = masterlbl.Text;
txtContent.Text = mastertxt.Text;
}
}
|
VB.NET
Code
Imports System.Web.UI.WebControls
Partial Public Class _Default
Inherits System.Web.UI.Page
Protected Sub
Page_Load(ByVal sender As Object, ByVal e As
EventArgs)
If Not IsPostBack Then
Dim masterlbl As Label = DirectCast(Master.FindControl("lblMaster"), Label)
Dim mastertxt As TextBox = DirectCast(Master.FindControl("txtMaster"), TextBox)
lblContent.Text = masterlbl.Text
txtContent.Text = mastertxt.Text
End If
End Sub
End Class
