Razor multiline syntax for grid column format

Question

I have a WebGrid that I am trying to define in an MVC4 razor view. I would like to define a column format using multiple lines for readability. The following works, with the format on one line:

@grid.GetHtml(
    columns: grid.Columns(
        grid.Column(
            header: "Address",
            format: (item) => @: @item.Address.Street1 @item.Address.Street2<br />@item.Address.City, @item.Address.State @item.Address.Zip
            )
        )
    )

The following gives a parser error, ; expected, on the first trailing parenthesis, and Invalid expression term ')' on the other trailing parentheses:

@grid.GetHtml(
    columns: grid.Columns(
        grid.Column(
            header: "Address",
            format: (item) => @: @item.Address.Street1 @item.Address.Street2<br />
                              @: @item.Address.City, @item.Address.State @item.Address.Zip
            )
        )
    )

After reading ScottGu's blog, I thought this was the proper multiline syntax. I have tried various placements of curly braces, semicolons, and parentheses, and I can't find a syntax that makes the parser happy.

After toying with it for a little while longer I was able to find a working version using the <text> tag.

@grid.GetHtml(
    columns: grid.Columns(
        grid.Column(
            header: "Address",
            format: @<text>@item.Address.Street1 @item.Address.Street2<br />
                           @item.Address.City, @item.Address.State @item.Address.Zip</text>
                )))

Maybe it has something to do with the multi-line lambda.

What about something like this:

@grid.GetHtml(
columns: grid.Columns(
    grid.Column(
        header: "Address",
        format: (item) => 
                        {
                          @: @item.Address.Street1 @item.Address.Street2<br />
                          @: @item.Address.City, @item.Address.State @item.Address.Zip
                        }
        )
    )
)

Not all code paths return a value in lambda expression of type 'System.Func' – egbrad May 16 '13 at 18:05
