how to remove _layout for admin dashboard – Asp.net

If you want to exclude Layout from view temporarily, you can return view from a controller action using this code

if(...) return PartialView("name",model);
return View("name",model)

When you return a partial view, it will show only a view, no a layout

If your wont to exclude a layout permanenly for some views, you can use this code inside of the view

@{
    Layout = null;
}

but don’t forget that a Layout usually contains the most of Javascript and css libraries. So it is better to create a special layout for some views.
or you can use ViewStart page

@{  
    string CurrentName = Convert.ToString(HttpContext.Current.Request.RequestContext.RouteData.Values["Controller"]);  
    dynamic Layout;  
    switch (CurrentName)  
    {  
        case "User":  
            Layout = "~/Views/Shared/_Layout.cshtml";  
            break;  
        default:  
            //Admin layout  
            Layout = "~/Views/Shared/_AdminLayoutPage.cshtml";  
            break;  
    }  
}
