Using data in a HTML.ActionLink inside a WebGrid.column, not possible?

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 t开发者_开发技巧he spelling)?

I should note that the link works when using the "Edit"-text, and that AccountNumber is a long.

Here is an example of how I do it with a date.

grid.Column(columnName: "Date", format: (item) => Html.ActionLink(((string)item.Date), "Edit", new { id = item.id })),          

You have to beware of using extension methods (Html.*) with dynamics (item)... it doesn't work well in csharp. When you do the new {} projection or call ToString, it's no longer dynamic. Alternatively, you could cast: (object)item.Id.

From here.

Just in case any one was wondering about how it should look in VB here is an example:

grid.Column("PersonID", "Admin", Function(modelItem) Html.ActionLink("View", "Details", New With {.id = modelItem.PersonID}))

In my case Derek Beattie solution is not working.

And I use this

 grid.Column(format: (item) => Html.ActionLink("Edit", "Edit", new { id = item.ID }), style: "column-action") 

My columns were being generated in the Model, where Html.ActionLink seems inaccessible. So I had to create the href and return it as an MvcHtmlString. This is what I ended up doing,

new WebGridColumn{ColumnName="FileName", Header= "File",
                Format = item => new MvcHtmlString("<a href='" + item.FileLink + "'>" + item.FileName +"</a>")

I have solved like this

grid.Column("Id", format: (item) => Html.ActionLink((string)item.id.ToString(), "Edit", new { id = item.id }))

I use following code for grid. It working for me.

@grid.GetHtml(
    columns: grid.Columns(
        grid.Column(header: "Serial No", format:@<text><div>@(item.WebGrid.Rows.IndexOf(item) + 1)</div></text>),
        grid.Column(columnName: "Stdname", header: "Student Name"),
        grid.Column(header: "Email ID", format:@<text><a href="mailto:@item.Email">@item.Email</a></text>),
        grid.Column(header: "EDIT",format: (item) => Html.ActionLink("Edit", "Edit", new { id = item.ID })),
        grid.Column(header: "DETAILS", format: (item) => Html.ActionLink("Details", "Details", new { id = item.ID })),
        grid.Column(header: "DELETE", format: (item) => Html.ActionLink("Delete", "Delete", new { id = item.ID }))
))

Hope this is helpful.

 grid.Column("GiftID",canSort:false, format: (item => Html.ActionLink((string)(@item.GiftID).ToString(), "Edit", new { GiftID = @item.GiftID })))
