Multi-statement Code blockYou can write multiple lines of server-side code enclosed in braces @{ ... } . Each line must ends with a semicolon the same as C#.
Razor pages have handler-methods which are HTTP verbs. So to call a method from your page you need to put On followed by the http verb you want then your method name . And in your view pass the name to the asp-page-handler without the OnPost or OnGet prefix or Async suffix.
Just add the id property to the html-attributes. That will override the default id generated by the editorfor-helper-methode.
This should work:
<span class="vote-up@(puzzle.UserVote == VoteType.Up ? "-selected" : "")">Vote Up</span>
@( condition ? "true" : "false" )
The key is to encapsulate the expression in parentheses after the @ delimiter. You can make any compound expression work this way.
In most cases the solution of CD.. will work perfectly fine. However I had a bit more twisted situation:
@(String.IsNullOrEmpty(Model.MaidenName) ? " " : Model.MaidenName)
This would print me " " in my page, respectively generate the source &nbsp;. Now there is a function Html.Raw(" ") which is supposed to let you write source code, except in this constellation it throws a compiler error:
Compiler Error Message: CS0173: Type of conditional expression cannot be determined because there is no implicit conversion between 'System.Web.IHtmlString' and 'string'
So I ended up writing a statement like the following, which is less nice but works even in my case:
@if (String.IsNullOrEmpty(Model.MaidenName)) { @Html.Raw(" ") } else { @Model.MaidenName }
Note: interesting thing is, once you are inside the curly brace, you have to restart a Razor block.
