How to set Masterpage to site master?

Rohan Ramani

6yAsked Dec 23, 2019, 11:11 PM769.NET

Hi,

I am opening the responsive site into mobile device.

It with switch master page to Site.Mobile.Master. So, code will not execute of Site.Master and return the null value error.

I need to set my included Site.Master when it is mobile device.

<%@ Page Title="Transaction" MasterPageFile="~/Site.Master" Language="C#" AutoEventWireup="true" CodeBehind="Trans.aspx.cs" Inherits="Merchant.Trans" %>

Hi, Rohan.
You can try below code
protected void Page_PreInit(object sender, EventArgs e)
        {
            if (Request.Browser.IsMobileDevice == true)
                MasterPageFile = "~/Site.Master";
        }
