Fixes the use of DataGrid Template Contexts for ExtraProperties

[carlosv14]

Description

Resolves #25465

TODO: As per Blazorise migration docs DataGrid Template Contexts now receive context objects instead of the raw row item and any code that assumes context is TItem should be updated. So the line var entity = context as IHasExtraProperties; should be var entity = context.Item as IHasExtraProperties; otherwise entity is null and propertyValue is also null.

Checklist

• I fully tested it as developer
• I documented it (or no need to document or I will create a separate documentation issue)

Hi @carlosv14, thanks for the fix!

Could you change the base branch of this PR from dev to rel-10.3? Since the issue was reported on 10.3, landing the fix on the oldest supported release branch is preferred — ABP's auto-merge bot will then forward it to rel-10.4 and dev automatically.

You can change the base branch via the "Edit" button next to the PR title on GitHub.

Thanks!

Pull request overview

Updates AbpExtensibleDataGrid to work with Blazorise 2.0+ DataGrid template contexts, where the template context is a context object (with an Item) rather than the row item itself. This restores rendering of ExtraProperties values in grids (fixing the regression reported in #25465).

Changes:

• Use context.Item (instead of context) when accessing the row entity for ExtraProperties rendering.
