ASP.NET Web API Help Page Part 1: Basic Help Page customizations

  • Article

Now that you have installed the ASP.NET Web API Help Page, I’m going to walk you through some of the basic customizations that you can do to make the help page more personalized.

Changing the help page URI

By default, the help page is available at /help. However you can easily change that in the HelpPageAreaRegistration.cs.

In the RegisterArea method, you can change the help page route URI to whatever you want. For example, the following will make the help page available at /document instead.

Providing API documentations

The help page package comes with an XmlDocumentationProvider which allows you to document your APIs using xml comments.

image

The ideal place to wire up the XmlDocumentationProvider is in HelpPageConfig.cs. The XmlDocumentationProvider constructor would take a physical path to your xml documentation file.

image

 // Uncomment the following to use the documentation from XML documentation file.
 config.SetDocumentationProvider(new XmlDocumentationProvider("physical path to your xml documentation"));

Once that’s done you should see the comments showing up on the help page.

Customizing the view

Changing the layout

You can change the look and feel of the help page using Razor layouts. This allows help page to inherit the look and feel of your existing sites.

First, make sure that your layout page have the following:

 @RenderBody()
 @RenderSection("scripts", required: false)

Then, open _ViewStart.cshtml and change the Layout path to your layout page.

image

For example the following will use the layout page under “Views/Shared” instead of “Areas/HelpPage/Views/Shared”.

 @{
     // Change the Layout path below to blend the look and feel of the help page with your existing web pages.
     Layout = "~/Views/Shared/_Layout.cshtml";
 }

Editing the CSHTMLs

The help page is mainly composed by two pages: Index.cshtml (lists all APIs) and Api.cshtml (describes one API). Each of these displays the model using DisplayTemplates and you can edit any of the cshtml files.

The following is a mapping of the cshtml files to the corresponding view in HTML.

Index.cshtml image
Api.cshtml image
ApiGroup.cshtml image
HelpPageApiModel.cshtml image
ImageSample.cshtml image
InvalidSample.cshtml image
Parameters.cshtml image
Samples.cshtml image
TextSample.cshtml image

    Hi Yao, First of all, I would like to thank you for sharing such a good tutorial. I have one question. In my scenario, I have the service in a self hosted manner. How can I configure help in my case? Thanks in anticipation!

    @Ahsan Currently, the Help Page package is implemented for web host only and you'll have to modify it to work on the self host. Basically you'll need to generate the HTML without using MVC, so instead of implementing the HelpController as a MVC Controller, you implement it as another ApiController. In that Help ApiController, you can use any templating engine you like (T4, RazorEngine, etc) to generate the documentation in HTML format and return it as an HttpResponseMessage. Hope this helps, Yao

    Hi Yao, thanks for sharing this great tutorial, I have read the comments I noticed it's not so simple for a Web Apo self host application, you'd mentioned that you will blog about that later, in the first series. Are you still going to blog about that? I hope so. But most of all thanks for sharing !! Greetings, Dave

    Hi xiaobao, For Q1 and Q2, part 2 of this series might help: blogs.msdn.com/.../asp-net-web-api-help-page-part-2-providing-custom-samples-on-the-help-page.aspx For Q3, can you not use XML comments like below to describe the complex parameter?        /// <summary>        /// Posts the specified value.        /// </summary>        /// <param name="value">        /// PropertyA - optional.        /// PropertyB - required.        /// </param>        public void Post(ComplexType value)        {        }
