how to ignore @RenderBody() inside if condition

Question

I have a page where I am validating a condition. if condition true display different page else displays the login page.

@if (sitemaintainmode == "false")
{
    <body>
   
        <div class="navbar navbar-default">
            <div class="container">
          
                    @Html.Partial("_LoginPartial")
               
            </div>
        </div>

        <div class="container body-content">
            @RenderBody()
        </div>
        @Html.Partial("_Footer")

      
        </script>
    </body>
}
else
{
   @RenderPage("~/Views/Account/Error.cshtml"); 
    
}

But it gives me an error -

The "RenderBody" method has not been called for layout page "~/Views/Shared/_Layout.cshtml".

This would be much better handled in the controller than the layout page — Zeph, Sep 20 '18 at 19:46
Yeap. In a `MVC` application usually such kind of decisions are taken before you get to the point where the actual view is rendered. I see that you check for maintenance. In this case maybe changing the routing would be a better solution and redirect all request to default action when the site is under maintenance. — Leron, Sep 20 '18 at 19:48
@Hob check this question: https://stackoverflow.com/questions/7580911/implement-down-for-maintenance-page I think it's pretty close to what you want to achieve, but in a better way. — Leron, Sep 20 '18 at 19:56
**Don't do this**. You are adding logic to view. A view is just to represent data. Your *logic* in this example should be done in the controller (or ActionFilter) and if it is determined to show the login page, then redirect there. — Erik Philips, Sep 20 '18 at 20:43

You can not ignore RenderBody() in your code because might be you use this Layout="~/Views/Shared/_Layout.cshtml" in your cshtml page.

Create seperate customeErrorPage (View) and Handle your condition in Controller and use return RedirectToAction("Login Or Error") or use return View("Login or Errorpage")

Hope this will help you.

Thanks!! As you suggested I added a condition in controller. it worked. public ActionResult Login(string returnUrl) { var sitemaintainmode = ConfigurationManager.AppSettings["IsSiteMaintenanceMode"]; if(sitemaintainmode == "true") { return View("Error"); } else { return View("Login"); } } – Hob Sep 21 '18 at 12:34

You could handle the action result in the controller, making a redirect to Error view in the Account controller or using customError in the web.config. For instance:

<customErrors mode="RemoteOnly" defaultRedirect="~/Home/Error_Generic/" >
  <error statusCode="500" redirect="~/Account/Error" />
</customErrors>
