I am trying to redirect to different content page through my master page but i don't want to refresh my master page.
As our master page is nothing but an content page only but i don't want to refresh master page content.
Ant technology in asp.net so that i can achieve it.

Thanks

try to use iframe instead masterpage.. :)
Check out this example

HTML

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <style>
        .iframrStyle
        {
            height: 1000px;
            width: 100%;
            border: none;
        }
    </style>
    <script>
        function SetPageURL(PageURL) {

            document.getElementById("MyFrame").src = PageURL; //iFrame source set dynamically
        }

    </script>
</head>
<body>
    <form id="form1" runat="server">
        <div class="Header">
            <%--Menu--%>
            <nav>
                <ul>
                    <li  önclick="SetPageURL('Home.aspx')">Home</li>
                    <li  önclick="SetPageURL('About.aspx')">About</li>
                    <li  önclick="SetPageURL('Contact.aspx')">Contact Us</li>

                </ul>

            </nav>

        </div>
        <div class="MainBody">
            <%--iframe--%>
            <iframe id="MyFrame" src="Home.aspx" class="iframrStyle">

            </iframe>

        </div>
        <%--footer--%>
        <div class="Footer">
        </div>

    </form>
</body>
</html>

You can call child page javascript function from parent page in this way.

JavaScript

document.getElementById('MyFrame').contentWindow.FuncName(); //FuncName() is a function of child page.

You can call patent page javascript function from child page in this way.

JavaScript

top.FuncName(); //FuncName() is a function of Parent page.

Hello friend, you can use Ajax UpdatePanel control in Master Page to refresh the content page only. Try the following code:

MasterPage.aspx:

XML

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<h1>Master Page</h1>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<div>
    <hr />
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
            </asp:ContentPlaceHolder>
        </ContentTemplate>
    </asp:UpdatePanel>
</div>

MasterPage.aspx.cs:

C#

protected void Page_Load(object sender, EventArgs e)
{
    Label1.Text = DateTime.Now.ToString();
}

ContentPage.aspx:

XML

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</asp:Content>

ContentPage.aspx.cs:

C#

protected void Button1_Click(object sender, EventArgs e)
{
    Label1.Text = DateTime.Now.ToString();
}

In this way the content page DateTime will be refreshed in every hit of the button, but DateTime on MasterPage will remain unchanged.

Let me know if you have any further query.
