Fixes #37233
Fixes #37234

Daria ...

• I may have missed some public API that you want to cover. I think thus far that this only has QueryParameterNamePrefix and GetPageUrl. Is there more API to call out?
• The diff might be a bit hard to read because of the versioning changes. You might have better luck looking at it with the internal review article.
• The PR includes [SupplyParameterFromSession] coverage.
• This PR will collect the rest of the Preview 5 coverage (at least for release notes) and be held until next Tuesday's release. I'll probably add Ondrej's form features to the release notes here later this week. The reference article updates for form features will probably go on a different PR.

Pull request overview

Adds .NET 11 Preview 5 QuickGrid SSR/URL-based navigation coverage to the QuickGrid reference article (under >= aspnetcore-11.0 monikers) and stages release-notes content (currently HTML-commented) for Preview 5 release day.

Changes:

• Adds new 11.0-monikered sections to quickgrid.md covering URL-based pagination, multiple grids on the same page, title-based sort identification, and the EnableUrlBasedQuickGridNavigationAndSorting AppContext switch.
• Reworks moniker fencing around existing "Sort by column," "Page items," and "Open and return from a details page" sections so legacy guidance remains for < aspnetcore-11.0.
• Drafts a (commented-out) Preview 5 release-notes blurb in aspnetcore-11/includes/blazor.md summarizing the same QuickGrid changes.

@dariatiurina ... I added the [SupplyParameterFromSession] coverage. It's probably a bit rough 🙈 in draft form, but it's reviewable. I plan to give it another edit tomorrow (Wednesday). You don't need to wait on that, however, to see if I have the technical details correct.

I also made updates to the temporary data (ITempData) coverage.

BTW ... This PR is probably going to collect the rest of the Blazor Preview 5 coverage. It will sit until release next Tuesday.

Thank you for your work! Here are some notes:

@wadepickett ... I think this 🐘 PR is ready now. I didn't change the Release Notes article date on this PR, so it's relying on being merged before #37241.

[wadepickett]

I realize this is outside of the PR scope, but I'll mention. Since we are checknig if Page even has a value, should it be declared nullable" int? Page

[guardrex]

I can address this, but it will need to be in like 30 minutes. If you want, I can patch it on a patch PR. Otherwise, we just need to wait another 30 minutes. I have a prior (quick) family obligation that I can't get out of.

[wadepickett]

Patch after is fine. Alerady approved. Up to you.

[guardrex]

My recollection is just that it goes to zero if not present in this case. There are a few examples that I need to look at, however, to make sure that they're all addressing this the same way. We might also need to make a remark about behavioral difference between nullable and non-nullable.

Yeah ... I recommend let's go ahead and merge this now. I'm going to run over and take care of the family situation. I'll be back soon and ping you probably in like an hour or so with a PR on this.

[guardrex]

I'll also add the NavigationManager to the earlier example.

Sorry for the poor timing! I'll get your feedback resolved as soon as I get back to the house. 🏃‍♂️🏃‍♂️🏃‍♂️🏃‍♂️

[wadepickett]

Approved. See the questions I had inline though.
