On HtmlHelper<T> we now support contextualizing an instance of
HtmlHelper<TBase> with a ViewDataDictionary<TDerived> in
ViewContext.ViewData.
This can happen in some situations when the model for a RazorPage has
been changed using a page application model convention.
In these cases we just build a new ViewDataDictionary<TBase> and pass in
the TDerived model as an instance.
- #7044
- move `IHttpResponseStreamWriterFactory` too
- add breaking change records e.g. for changes to `BodyModelBinder[Provider]` constructors
- these changes relate to previously-"internal" constructors and one property
nits: take VS suggestions for changed files
- #6662
- users can now provide a `name` or `data-valmsg-for` attribute to avoid `ArgumentException`s
- affects `<input>`, `<select>`, `<textarea>` elements and validation message `<div>`s
- remove `fullName` check in `DefaultHtmlGenerator.GetCurrentValues(...)` entirely
The new workaround is _not_ identical to changing `ViewData.TemplateInfo.HtmlFieldPrefix`
- does not change where expression values are found in `ModelState` or `ViewData`
- likely needs to be combined with additional workarounds i.e. for advanced use only
nits:
- clean up some excessive argument naming; add a few missing argument names
- take VS suggestions in changed classes e.g. inline a few variable declarations
- clean up some test data
- This functionality can be disabled by setting the `Switch.Microsoft.AspNetCore.Mvc.AllowJsonHtml` switch in an app.config.
- Updated tests to react to this new behavior.
- Exposed a new `PublicSerializerSettings` property on `JsonOutputFormatter` so we can accurately copy settings from the used output formatter in `JsonHelper`.
We have all of these executors but they aren't really
documented/supported for extensibility today. This change introduces a
pattern for action result executors so we can make them extensible.
- cherry-picked from 7e4a8fe in dev
- #6648
- a different take on #4871
- `DateTime` can also round-trip `DateTimeKind.UTC` with `[DataType("datetimeoffset")]` or `[UIHint("datetimeoffset")]`
- since they're now handled differently by default, add more `DateTime` tests
- expand tests involving `Html5DateRenderingMode.CurrentCulture`

This change logs when we encounter and exception reading temp data from a
cookie and swallows the exception. Additionally, we clear the cookie so
that this won't happen on subsequent requests.
This will handle cases where data protection is misconfigured, or a
request just has general garbage in the cookies.
- Prior to this change using asp-page-handler on its own did not create correct `<form>` elements. There were multiple issues, one as that the `FormTagHelper` would purposefully drop into a no-op code path. Second is the `DefaultHtmlGenerator` didn't call through to the `UrlHelper` correctly.
- Added functional test cases to validate asp-page-handler can live on its own on a form tag. This also included adding a variant where method="post".
- Added a `FormTagHelper` unit test to validate the `PageHandler` property is consumed properly.
#6208
- #5642
- lazy-load `ValidationEntry.Model`
- avoids `Exception`s when moving to a property that will not be validated
nits:
- remove duplicate code in `ValidationVisitor`
- clarify "all properties of" doc comments
- also add missing `<param>` doc in `ViewDataInfo`
- #5499
- switch `foreach` to `for` and use less Linq when accessing `modelMetadata.Properties`
- change backing field for `ModelExplorer.Properties` from a list to an array
- #1999
- may have reordered the precedence comments as I double-checked the implementations
- `CheckBox()` and `RadioButton()` were examples of such updates
nits:
- use SSL in documentation links
- simplify mentions of format strings
- remove a few phrases that didn't say much and duplicated `<remarks>`
- #3918
- don't repeat allocations for identical calls; helps w/ e.g. label / input / validation clusters
- add `NameAndIdProvider`; it stores `PreviousNameAndId` in `HttpContext.Items`
- `PreviousNameAndId` allocated only when `string`s are allocated e.g. "id"s were sanitized
- #3918
- lazy-load `TagBuilder.InnerHtml`; add `HasInnerHtml` property for conservative use
- depends on aspnet/HtmlAbstractions@0781b5a (adds `HtmlContentBuilder.Count`)
- don't use a `HtmlContentBuilder` at all in `DefaultHtmlGenerator.GenerateValidationSummary()`
- avoid instantiating `HtmlContentBuilder` when short-circuits make it unnecessary
- provide correct `HtmlContentBuilder` capacity where known
- #3918
- precompute size of `StringBuilder` in `ExpressionHelper`
- reduce `string` allocations in `ViewDataEvaluator`
- also get rid of `Enumeration` state machines
- reduce the size of a few objects; use more expression-valued properties
- e.g. don't store `_modelType` in `ModelExplorer`
- add `EmptyArray<TElement>`; make empty arrays consistently `static`
- avoid `string.Split()` in HTML and tag helpers
nits:
- make `ExpressionHelperTest` tests more stringent
- correct `Message` for an `ArgumentNullException`
- remove excess `using`s in classes I touched (but often ended up leaving otherwise unchanged)
- improve doc comments
- remove `ToString()` call on a `string`
- avoid encoding `string.Empty`
- fix test file name
- remove useless variables
- correct spelling
- improve whitespace
- #5028
- helpers similar to our HTML or tag helpers can use the new singleton to examine or add validation attributes
- in the most common case, helpers add validation attributes to a `TagBuilder`
- separate `DefaultValidationHtmlAttributeProvider` from `DefaultHtmlGenerator`
- avoids creating two instances of the `DefaultHtmlGenerator` singleton
- would be even uglier to require callers to cast an `IHtmlGenerator` to `ValidationHtmlAttributeProvider`
- `[Obsolete]` old `DefaultHtmlGenerator` constructor
- #5209
- update affected `HtmlHelperValiationSummaryTest` and functional tests
- add `ValidationSummaryTagHelperTest` tests to cover related scenarios
##### Behaviour changes when no errors exist for the model:
###### Tag helper
``` html
<div asp-validation-summary="ModelOnly" class="order"><h3>Oopsie<h3></div>
```
previously generated
``` html
<div class="order validation-summary-errors"><h3>Oopsie</h3><ul><li style="display:none"></li>
</ul></div>
```
and now generates
``` html
<div class="order"><h3>Oopsie</h3></div>
```
###### HTML helper
``` c#
@Html.ValidationSummary(excludePropertyErrors: true, message: "Oopsie")
```
previously generated
``` html
<div class=\"validation-summary-errors\"><span>Oopsie</span>
<ul><li style=\"display:none\"></li>
</ul></div>
```
and now generates nothing (`@HtmlString.Empty`).
