Razor HTML Conditional Output

Question

I have a list of items I want to output as the contents of a main (the main in not included below). Each Item has 3 attributes: a Section Name, a Label and a Value. Each item is enclosed in a and everytime the Section Name changes I have to open a (and close the previous one, if any). I'm using a Razor view with this code: ``` @foreach (LocalStorageItem lsi in Model) { string fld_name = "f_" + lsi.ItemName; if (lsi.SectionName != sn) { if (sn != "") { Html.Raw(""); } sn = lsi.SectionName;

@sn

Html.Raw("

"); }

@lsi.ItemName

.

} @if (Model.Count != 0) { Html.Raw("

"); } ``` The problem is: each time the Section Name changes no fieldset tag (open and/or close) is generated. Where am I wrong? If I don't use Html.Raw (or @: as an alternative) the VS2010 parser signals an error.

Accepted Answer

Calling `Html.Raw` returns an `IHtmlString`; it doesn't write anything to the page. Instead, you should write ``` @: ``` Using `@:` forces Razor to treat it as plain text, so it doesn't need to be well-formed. However, your code can be made much cleaner by calling `GroupBy` and making a nested `foreach` loop.
