Class RazorTyped
Base class for v16 Typed Razor files. Use it to create custom CS code in your App.
It provides the ServiceKit16 on property Kit which contains all the popular services to create amazing stuff.
[PublicApi]
public abstract class RazorTyped : RazorComponentBase, IHasLog- Inheritance

objectWebPageExecutingBaseWebPageRenderingBaseWebPageBaseRazorComponentBaseRazorTyped
- Implements
- Derived
Remarks
Important: This is very different from Razor12 or Razor14, as it doesn't rely on dynamic code.
Be aware of this since the APIs are very different - see Typed Code.
Properties
AllResources
Stack of all Resources in the System, merging Resources of View, App, Site, Global etc. Will retrieve values by priority, with View-Resources being top priority and Preset-Resources being the lowest.
Tip
If you know that Resources come from the App, you should prefer App.Resources instead.
That is faster and helps people reading your code figure out where to change a value.
public ITypedStack AllResources { get; }Property Value
AllSettings
Stack of all Settings in the System, merging Settings of View, App, Site, Global etc. Will retrieve values by priority, with View-Settings being top priority and Preset-Settings being the lowest.
Tip
If you know that Settings come from the App, you should prefer App.Settings instead.
That is faster and helps people reading your code figure out where to change a value.
public ITypedStack AllSettings { get; }Property Value
App
The current App object (with strictly typed Settings/Resources).
Use it to access App properties such as Path or any data in the App.
public IAppTyped App { get; }Property Value
Customize
BETA! v17.03+
[WorkInProgressApi("Experiment v17.03+")]
protected ICodeCustomizer Customize { get; }Property Value
Html
Helper for Html.Raw - for creating raw html output which doesn't encode > and <.
Also has helpers such as .Partial(...)
public override IHtmlHelper Html { get; }Property Value
Kit
public ServiceKit16 Kit { get; }Property Value
Link
Link helper object to create the correct links
public ILinkService Link { get; }Property Value
- ILinkService
A ILinkService object.
Log
The logger for the current Razor / WebApi which allows you to add logs to Insights.
public override ICodeLog Log { get; }Property Value
MyContext
This Context tells you about the environment, such as
- the current User
- the Page
- the View
- the Site
It's supposed to replace direct access to Dnn or Oqtane object in Razor and WebAPI code, allowing hybrid code that works everywhere.
public ICmsContext MyContext { get; }Property Value
Remarks
New in v11.11
MyData
All the data which the current Template received, based on the View configuration. There are a few common scenarios:
- If it's a simple view, then this will just contain streams with the main Item(s) and Header
- If the view expects no data, it will just contain a
Defaultstream containing no items - If the view has a Query behind it, then MyData will have all the streams provided by the Query
public IBlockInstance MyData { get; }Property Value
- IBlockInstance
MyHeader
The Header-Item belonging to this Template/Module. This data is edited by the user directly on this specific module. In some cases it can also be a pre-set item configured in the View to be used if the user has not added any data himself.
public ITypedItem MyHeader { get; }Property Value
MyItem
The main Item belonging to this Template/Module. This data is edited by the user directly on this specific module. In some cases it can also be a pre-set item configured in the View to be used if the user has not added any data himself.
If this view can have a list of items (more than one) then this contains the first item. To get all the items, see ToSic.Sxc.Code.Internal.IDynamicCode16.MyItems
public ITypedItem MyItem { get; }Property Value
MyItems
List of all Items belonging to this Template/Module. This data is edited by the user directly on this specific module. In some cases it can also be a pre-set item configured in the View to be used if the user has not added any data himself.
If this view is configured to only have one item, then this list will only contain one item. Otherwise it will have as many items as the editor added.
public IEnumerable<ITypedItem> MyItems { get; }Property Value
MyModel
Data passed to this Razor template by a caller.
This is typical for Razor components which are re-used, and called from other Razor templates using @Html.Partial("filename.cshtml", new { thing = 7 }).
public ITypedModel MyModel { get; }Property Value
MyPage
Information about the current Page (called Tab in DNN). It's especially useful to get current URL Parameters.
public ICmsPage MyPage { get; }Property Value
MyUser
Information about the current user. It's especially useful to see if the user has any kind of Admin privileges.
public ICmsUser MyUser { get; }Property Value
MyView
View-information such as the view Name, Identity or Edition.
public ICmsView MyView { get; }Property Value
Remarks
New in v12.02
UniqueKey
A unique, random key for the current module. It's recommended for giving DOM elements a unique id for scripts to then access them.
It's generated for every content-block, and more reliable than Module.Id
since that sometimes results in duplicate keys, if the many blocks are used inside each other.
It's generated using a GUID and converted/shortened. In the current version it's 8 characters long, so it has 10^14 combinations, making collisions extremely unlikely. (currently 8 characters)
Tip
To get a unique key which is based on additional objects such as Entities, use the UniqueKeyWith(params object[]) method.
public string UniqueKey { get; }Property Value
Remarks
If you get a fresh IKeyService it will also create a new UniqueKey.
So your code should usually use the built-in property UniqueKey which comes from the shared ServiceKit Key.
Methods
AsEntity(ICanBeEntity)
Unwraps a dynamic entity or ITypedItem back into the underlying IEntity
public IEntity AsEntity(ICanBeEntity thing)Parameters
thingICanBeEntity
Returns
- IEntity
A normal IEntity
AsItem(object, NoParamOrder, bool?, bool?)
Convert something to a ITypedItem. This works for all kinds of IEntitys, IDynamicEntitys as well as Lists/IEnumerables of those.
Will always return a single item. If a list is provided, it will return the first item in the list. If null was provided, it will return null.
public ITypedItem AsItem(object data, NoParamOrder noParamOrder = default, bool? propsRequired = null, bool? mock = null)Parameters
dataobjectAn original object which can be converted to a TypedItem, such as a IEntity .
noParamOrderNoParamOrderpropsRequiredbool?make the resulting object strict, default
truemockbool?Specify that the data is fake/mock data, which should pretend to be an Item. Default is
false
Returns
Remarks
New in v16.02
AsItems(object, NoParamOrder, bool?)
Convert an object containing a list of Entities or similar to a list of ITypedItems.
public IEnumerable<ITypedItem> AsItems(object list, NoParamOrder noParamOrder = default, bool? propsRequired = null)Parameters
listobjectThe original list which is usually a list of IEntity objects.
noParamOrderNoParamOrderpropsRequiredbool?make the resulting object strict, default
true
Returns
Remarks
New in v16.01
AsList<T>(object, NoParamOrder, bool)
Convert a list of Entities or TypedItems into a strongly typed list.
Typically, the type will be from your AppCode.Data.

Returns
- IEnumerable<T>
Type Parameters

Remarks
Release in v17.05
AsStack(params object[])
Create a typed object which will provide all the properties of the things wrapped inside it. The priority is first-object first, so if multiple items have the property, the first in the list will be returned.
public ITypedStack AsStack(params object[] items)Parameters
itemsobject[]objects to stack together
Returns
AsStack<T>(params object[])
Create a custom-typed object which will provide all the properties of the things wrapped inside it. The priority is first-object first, so if multiple items have the property, the first in the list will be returned.
public T AsStack<T>(params object[] items) where T : class, ITypedItemWrapper16, ITypedItem, new()Parameters

Returns
- T
Item of the custom type
Type Parameters

AsTyped(object, NoParamOrder, bool?)

GetCode(string, NoParamOrder, string)
Create an instance of a class in a .cs code file.
