MSChart and ASP.NET MVC Partial View

Question

I'm currently trying to add an MSChart to a partial view in ASP.NET MVC RTM. I have reviewed the following blog entry, and I'm currently investigating Option B. If I take my code an place it inside a View (ASPX) Page and it works fine, but when I copy the exact code into a Partial View (ASCX) I get the following excpetion: "CS1502: The best overloaded method match for 'System.IO.TextWriter.Write(char)' has some invalid arguments ". Has anyone else run into this and solved the issue or do they know why it's impossible to use this strategy with MSChart and MVC?

My code is exactly what's in option B on the linked article.

Answer 1

I'm not exactly sure what the problem is, but the most common cause of that error is that you've used a statement inside a "<%= %>" block rather than an expression. Since the code within a "<%= %>" block is placed within a call to System.IO.TextWriter.Write, it must be an expression. Statements must be enclosed within "<% %>" blocks, rather than "<%= %>".

The code you referenced should be working just fine on a partial view, if it runs on a "regular" view. Make sure that the call to RenderPartial is in a "<% %>" block because RenderPartial does not actually return anything, it does the rendering directly in place.
