Title Body

I have the following WebGrid in my ASP.NET MVC3 test application. It displays a list of customers: @grid.GetHtml( tableStyle: "grid", headerStyle: "head", alternatingRowStyle: "alt", columns: grid.Columns ( grid.Column(format: (item) => Html.ActionLink("Edit", "Details", new { id = item.id })), grid.Column("Address.CompanyName"), grid.Column("Address.City") ) ) The interesting part here is the Edit-link I've added in the first column. I would like to use the customers account number instead of the plain "Edit"-test. However, it causes me a great deal of problems to do so. I've tried: grid.Column(format: (item) => Html.ActionLink(item.AccountNumber.ToString(), "Details", new { id = item.id })), However, it seems like there is something i don't understand about how this works because i keep getting this exception: CS1502: The best overloaded method match for 'System.Web.Helpers.WebGrid.Column(string, string, System.Func<dynamic,object>, string, bool)' has some invalid arguments Can anyone explain to me why this isn't working? What is the difference between "Edit" and item.AccountNumber.ToString() (apart from the spelling)? I should note that the link works when using the "Edit"-text, and that AccountNumber is a long.
