Quick Reference for all APIs

This is a quick CheatSheet to provide you with a reference to most APIs you'll use.

This uses a base class of @inherits Custom.Hybrid.RazorTyped. Most samples would not work on older Razor base classes such as @inherits Custom.Hybrid.Razor14 as that provides different objects and methods.

The samples can differ based on your Razor base class or if you're running an old version.
Selected: Typed (2sxc 16+) Switch to Dynamic (Razor14 or below)

Razor Basics @...

Common basics for working with Razor.

  1. Show firstName (string): Terry
  2. Show birthday (DateTime):
    4/28/1948 12:00:00 AM
  3. Show birthday (DateTime, formatted):
    1948-04-28
  4. Show age (int): 76
  5. Show decades (int): 7
  6. Show decadesFloat (float): 7.6
  7. Show decadesInt (int): 7
@inherits Custom.Hybrid.Razor14

@{
  // Create variables using var; compiler detects the type
  var firstName = "Terry";
  var birthday = new DateTime(1948, 04, 28);
  var age = DateTime.Now.Year - birthday.Year;
  var decades = age / 10;             // int division - decades will be int
  var decadesFloat = (float)age / 10; // float div - so it be float
  int decadesInt = (int)decadesFloat; // this drops the decimal places
}
<ol>
  <li>Show firstName (string): @firstName</li>
  <li>
    Show birthday (DateTime): <br>
    @birthday
  </li>
  <li>
    Show birthday (DateTime, formatted): <br>
    @birthday.ToString("yyyy-MM-dd")

  <li>Show decadesFloat (float): @decadesFloat</li>
  <li>Show decadesInt (int): @decadesInt</li>

A common task is to link to a specific page or to stay on the same page but with different URL parameters. 

⬇️ Result | Source ➡️

Normally you would use the following in an href attribute.

Current Page

  1. This page URL:
    https://2sxc.org/dnn-tutorials/en/razor
  2. This page url params:
    blade=page&tut=quickref
  3. Link this page without params:
    https://2sxc.org/dnn-tutorials/en/razor
  4. Link this page with same params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref
  5. Link this page with same params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref
  6. Link this page with more params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref/another/more/27/more/42
  7. Link this page remove params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref
  8. Link this page replace params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref/quick-ref-typed/test

Another Page

This only works if you don't have a page 12, otherwise you'll see an error in the url.

  1. Link to page 12 without params:
    https://2sxc.org/dnn-tutorials/en/razor#error-unknown-pageid-12
  2. Link to page 12 with current params:
    https://2sxc.org/dnn-tutorials/en/razor/blade/page/tut/quickref#error-unknown-pageid-12

Reuse Razor and CSharp Files

  1. Code - Function and Similar Helpers

    Normal C# functions are the basic block for reusing code. 

  2. Use Shared C# Code

    Use a shared razor file to hold multiple functions / helpers, and call them one-by-one as needed. 

  3. Reuse Code and Razor Templates

  1. Use Shared C# Code

    Use a shared razor file to hold multiple functions / helpers, and call them one-by-one as needed. 

Razor doesn't know about types inside code files, so you need some tricks to work with objects which are passed around. 

⬇️ Result | Source ➡️

Working with anonymous objects

The only way to get values from an anonymous object created elsewhere is using AsTyped(... as object). Everything else will 🚫.

  1. Anon: { Name = John, Age = 30 }
  2. Anon Type: <>f__AnonymousType0`2[System.String,System.Int32]
  3. aTyped.Name ✅: John
  4. Anon.Name 🚫: ⚠️ Exception: 'object' does not contain a definition for 'Name'
  5. anonDyn.Name 🚫: ⚠️ Exception: 'object' does not contain a definition for 'Name'
  6. aTypedDyn.Name 🚫: ⚠️ Exception: 'ToSic.Sxc.Data.Internal.Typed.WrapObjectTyped' does not contain a definition for 'Get'

Working with ITyped objects

If the returned object is based on ITyped, things are a bit easier. But you must still ensure that Razor knows the type.

  1. Name ✅: John
  2. Name (string) ✅: John

Working with real objects

If the returned object is based on a class, things are a bit easier.

  1. Person: ReturnObjects+Person
  2. Person Type: ReturnObjects+Person
  3. Person.Name ✅: John
  4. pTyped.Get("Name") ✅: John
  5. pTyped.String("Name") ✅: John
  6. pTypedDyn.Get("Name") 🚫: ⚠️ Exception: 'ToSic.Sxc.Data.Internal.Typed.WrapObjectTyped' does not contain a definition for 'Get'

Working with dictionaries

If the returned object is based on a dictionary, things are a bit easier. This is because dynamic will be able to work with it, but it's not type safe.

  1. dicDyn: System.Collections.Generic.Dictionary`2[System.String,System.String]
  2. dicDyn Type: System.Collections.Generic.Dictionary`2[System.String,System.String]
  3. dicDyn Count ✅: 2
  4. dicDyn["Name"] ✅: John
  5. dic: System.Collections.Generic.Dictionary`2[System.String,System.String]
  6. dic Type: System.Collections.Generic.Dictionary`2[System.String,System.String]

Work with Content Items - MyItem

MyItem is the object which contains the first thing added by the editor on the current block.

Every view/template receives prepared data, usually on the MyItem object.

Douglas Adams on MyItem

Id, Guid and Title are built-in properties

  1. Id: 45474
  2. Guid: 36726e4e-21cd-4c00-9ce8-72080f8935da
  3. Title: Douglas

Use Get(…) if you don't care about the var type...

  1. Name: Douglas
  2. Birthday: 3/11/1952 12:00:00 AM

... or Get<T>(…) which will try to treat as the expected type.

  1. Birthday Get<string> 03/11/1952 00:00:00
  2. Birthday Get<DateTime> 3/11/1952 12:00:00 AM
  3. Birthday Get<bool> False
  4. Birthday Get<int> 0

Use typed methods such as .String(…) if you care about the variable type.

  1. Name (strings): Douglas Adams
  2. Birthday: 3/11/1952
  3. Is Alive: False
  4. Fav Num. Int: 42
  5. Fav Num. Float: 41.99

Use fallback: … to handle empty values or conversion problems.

  1. Name (strings): Douglas
  2. Name (int): 12345

Use .Attribute(…) to safely encode properties. Mouse over this to see the effect.

JavaScript - Working with Razor and WebApi

Loading JavaScripts is standard HTML using <script src="..."< tags. What more challenging is getting the right path to scripts in this app or relative to the current Razor file.

Load a JavaScript relative to the App folder (see message/console):

A core challenge is to activate JavaScripts only when needed - and when all dependencies are loaded. This is what turnOn does. It checks if all specified JS objects exist, and then triggers the JS code.

This example passes data to the JS, so it can be parameterized:

We can also pass in more sophisticated data:

  // get div in html with id 'turnOn1-message' and show "Hello World!"
  const tag = document.getElementById('turnOn1-message')
  tag.innerHTML = 'Hello from turnOn1.js! This was activated using turnOn';

Work with the new UniqueKey with JavaScript - new v16.04 🌟

The UniqueKey is a new feature in 2sxc 16.04 which allows you to create unique IDs for HTML elements. The value of UniqueKey is the same in all Razor and C# files for the same Content-Block.

⬇️ Result | Source ➡️

This separate Razor will create a div for the resulting message, based on the same UniqueKey which is m-jVigs0

window.quickReference.demoUniqueQuey = function (ids) {
  document.getElementById(ids.buttonId)
    .addEventListener("click", function () {
      const msg = 'The button was pressed. ' +
      'This was only possible thanks to the unique id using UniqueKey. ' + 
      'The ID this time was: ' + ids.buttonId + '.';

      document.getElementById(ids.messageId).innerHTML = msg;

Sometimes you need a UniqueKey which also depends on other objects. For example, you may need to have a UniqueKey which also uses another value - or many. This is done using @Kit.Key.UniqueKeyWith(...).

If the UniqueKey is based on known object types such as Entities, this works very well. For example, you may need to loop through a list of items, and each item needs a unique key.
