    <p>I have a Helper method that I need to use across multiple views. I tried to using the following information: <a href="http://weblogs.asp.net/scottgu/archive/2011/05/12/asp-net-mvc-3-and-the-helper-syntax-within-razor.aspx" rel="nofollow">http://weblogs.asp.net/scottgu/archive/2011/05/12/asp-net-mvc-3-and-the-helper-syntax-within-razor.aspx</a>. I have defined this Helper method in /App_Code/Helpers.cshtml. My views are located at</p> <pre><code>/resources/_Layout.cshtml /Views/Index.cshtml /Views/Home/Index.cshtml </code></pre> <p>If I reference my Helper function in _Layout.cshtml everything works fine. However, if I reference my Helper function in the other views, I get a runtime error. The runtime error says:</p> <p>CS0103: The name 'MyFunction' does not exist in the current context</p> <p>My Helper method looks like the following:</p> <pre><code>/App_Code/Helpers.cshtml ------------------------ @helper MakeUrlRelative(string url) { @MyNamespace.MyClass.MakeUrlRelative(HttpContext.Current.Request, url) } </code></pre> <p>When I reference it in /Views/Index.cshtml, I use it like this:</p> <pre><code>&lt;link rel="stylesheet" href="@MakeUrlRelative("/resources/css/app.css")" /&gt; </code></pre> <p>When I reference it in /Views/Home/Index.cshtml</p> <pre><code>&lt;a href="@MakeUrlRelative("/home/page2")"&gt;click me&lt;/a&gt; </code></pre> <p>As you can see, I'm referencing the MakeUrlRelative method the same way. Its like the Helpers.cshtml file isn't accessible from /Views/Home/Index.cshtml. What would cause this?</p>

    1. COCan you post your helper definition, and a sample view where you try to call it but fails?

    3. COIt strange... based on your code non of the calls should work. You are missing the class name `Helpers` in both cases: e.g it should be `@Helpers.MakeUrlRelative("/home/page2")` (razor generates a static class from each file in app_code with the name of the file)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
