CODE - R

Recently, I encounter the bug of code CS1513 while trying to compile old project of MVC3 into newer version.

Compiler Error Message: CS1513: } expected

I found out that without proper usage of Razor syntaxes, you will encounter this when you upgraded MVC to latest version.

There are several ways might cause you this error. For example,

Instead of

@if(@variable)

You should

@if(variable)

Instead of

 @{int a = @Model.Property }

You should

@{int a = Model.Property }

Conclusion, you should be aware of the Razor V3 Advanced Parser feature which is different with the old version.

In my recent upgrade from MVC 3 to MVC 5, I encountered another issue/bug in system which JSONResult return null is working properly in MVC3 became an error in MVC5.

So, the code below,

return Json(null, JsonRequestBehavior.AllowGet);

should be changed to,

return Json(string.Empty, JsonRequestBehavior.AllowGet);

It should return empty string to avoid being recognized as error.

Cheers!

To remove the text in Edit button, we set it to empty text E.g.

You could also include some additional CSS to remove the default margin of the command icon. E.g.

Meanwhile, for CancelText and UpdateText methods. E.g.
