gridview-templatefield-regression

gridview-templatefield-regression is a skill for Claude Code, Codex from FritzAndFriends/BlazorWebFormsComponents. It costs 25 tokens per session (486 once invoked), scanned A, original, MIT.

A regression-testing guide for GridView TemplateField migrations. GridView is a Web Forms data table, and a TemplateField is a column that can contain controls or custom markup rather than just plain text.

In plain words
What is it for?
Use it when changing GridView conversion code to test TemplateField columns containing text boxes, checkboxes, expressions, mixed column types, or only TemplateFields.
Why use it?
It catches migration changes that accidentally turn custom columns into simple text columns or remove controls nested inside them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gridview-templatefield-regression scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Use this when changing the Web Forms to Blazor CLI markup pipeline anywhere near GridView column transforms, template context handling, data-binding expression rewrites, or asp-prefix stripping. TemplateField preservation is a cross-transform behavior, so regressions can appear even when each individual transform still looks correct in isolation.

Patterns

  • Treat TemplateField preservation as an ordered pipeline contract:
    • DisplayExpressionTransform
    • AspPrefixTransform
    • DataBindingAttributeTransform
    • AttributeStripTransform
    • GridViewColumnItemTypeTransform
    • TemplateContextTransform
  • Keep regression coverage at two levels:
    1. Transform-only markup assertions through TestHelpers.CreateDefaultPipeline().
    2. Full-file migration assertions through MigrationPipeline.ExecuteAsync().
  • Cover these GridView shapes explicitly:
    • TemplateField with inner TextBox
    • TemplateField with inner CheckBox
    • TemplateField with inline display expression only
    • Mixed BoundField + TemplateField siblings
    • GridView with only TemplateField columns
  • Assert both preservation and non-regression:
    • Expected <TemplateField ...> count remains stable
    • Inner controls survive as BWFC components (<TextBox>, <CheckBox>)
    • ItemTemplate Context="Item" is present
    • No unexpected fallback <BoundField> appears for template-only columns

Examples

  • tests/BlazorWebFormsComponents.Cli.Tests/TransformUnit/GridViewColumnItemTypeTransformTests.cs
  • tests/BlazorWebFormsComponents.Cli.Tests/PipelineIntegrationTests.cs

Anti-Patterns

  • Testing only GridViewColumnItemTypeTransform in isolation after changing template-related transforms.
  • Verifying only the first GridView column and assuming later TemplateField siblings survived.
  • Accepting output that preserves the TemplateField shell but drops nested controls or display expressions.
  • Changing transform order in Program.cs without mirroring the same coverage through tests/BlazorWebFormsComponents.Cli.Tests/TestHelpers.cs.
