Why Razor HTML Partial View not rendering between 'If' Block?

Question

I am trying to render a Razor html Partial view based on a ViewBag condition, but I always get compliation errors.

 @{

     if (ViewBag.Auth)
     {
        @Html.RenderPartial("_ShowUserInfo")
     }

 }

I also tried...

 @if (ViewBag.Auth)
 {
    @Html.RenderPartial("_ShowUserInfo")
 }

Error message:
Compiler Error Message: CS1502: The best overloaded method match for                  
'System.Web.WebPages.WebPageExecutingBase.Write(System.Web.WebPages.HelperResult)' 
has some invalid arguments

Answer 1

You need to cast ViewBag.Auth to boolean

 @if ((bool)ViewBag.Auth)
 {
    @{ Html.RenderPartial("_ShowUserInfo");  } 
 }

Also you need to use @{ } syntax with RenderPartial

Answer 2

Try using like this..

@if (ViewBag.Auth)
 {
    @{ Html.RenderPartial("_ShowUserInfo") }
 }
