Question

I’ve run into a couple different exceptions with this block of code in one of my views:

<% if (Model.Book.ReviewReference == null)
   {%>
       <%=Html.ActionLink("Rate / review this book", "Create", "Review", null, new { id = "reviewLink" }) %>
      <% Html.RenderPartial("CreateReview");
   }
   else
   {%> 
       <%= Html.ActionLink("Edit this book's rating / review","Edit", "Review", new { reviewID = Model.Book.ReviewID}, new {id = "reviewLink"}) %>
        <% Html.RenderPartial("EditReview", Model.Book.Review, new ViewDataDictionary());
   }  %>

The first error I encountered was described here:
link text

thus the Html.RenderPartial("EditReview", Model.Book.Review, new ViewDataDictionary()) you see towards the end there.

Another problem I encountered is when the if condition is evaluated for a ReviewReference that is in fact null, the else statement is still being reached somehow, and the second partial view is making an unsuccessful attempt to render itself.

Have I used these alternating inline-code tags in an incorrect manner? How does one go back and forth between <% %> and <%= %> properly?

Thank you.

Edit:

OK, I marked an answer too soon. I just tried it with the given code from the answer, and that else block is still being evaluated, and trying to pass null objects to the partial view…darn it.

Answer 1

OK, so it turns out my tag usage was fine, but my if condition was off. It needed to be:

if (Model.Book.ReviewReference.EntityKey == null)

I was missing the EntityKey property.
