Walkthrough

The data grid now tracks clicks and double-clicks on controls inside cells. Row and cell handlers skip their click actions while a control click is active. Built-in cells also stop double-click propagation.

Changes

DataGrid control click handling

Layer / File(s)	Summary
Track clicks on nested targets src/BlazorUI/Bit.BlazorUI.Extras/Components/DataGrid/BitDataGrid.ts, src/BlazorUI/Bit.BlazorUI.Extras/Components/DataGrid/BitDataGrid.razor.cs, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/DataGrid/BitDataGridTests.cs	The renamed JavaScript watcher tracks nested surfaces and cell controls. It reports control-click state changes to .NET. Failed interop calls clear the watcher flag so a later render can retry.
Gate row and cell events src/BlazorUI/Bit.BlazorUI.Extras/Components/DataGrid/BitDataGridRow.razor, src/BlazorUI/Bit.BlazorUI.Extras/Components/DataGrid/BitDataGridCell.razor, src/BlazorUI/Tests/Bit.BlazorUI.Tests/Components/Extras/DataGrid/BitDataGridTests.cs	Row and cell handlers skip click and double-click callbacks while a control click is active. Built-in cells stop double-click propagation. Tests cover row and cell events, keyboard detail expansion, and built-in controls.

Merge Risk: Moderate · previous review 6f212

Clicks on cell controls may still trigger row or cell actions, and clickable anchors without href attributes are not recognized as controls. Resolve these gaps before merging.

Full details: Linked Issues check

Explanation

The changes satisfy issue #14316. watchNestedTargets reports cell-control clicks to BitDataGrid. BitDataGridCell skips cell click and double-click handlers when a control is active. BitDataGridRow skips row handlers in the same condition. Built-in reorder, detail, selection, command, and tree-toggle cells now stop double-click propagation. Tests cover template cell clicks, double-clicks, keyboard detail expansion, and built-in controls.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #14316. The C# callback, TypeScript watcher rename and retry behavior, cell and row event guards, built-in propagation guards, and focused tests all support control-event propagation handling in BitDataGrid.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 3 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

_{I’m a rabbit by the grid,
Where buttons keep their clicks in.
Rows stay still when controls are pressed,
Double-clicks no longer test.
Keyboard detail still opens wide,
I hop along the tested side.}

Review comments at
@src/BlazorUI/Bit.BlazorUI.Extras/Components/DataGrid/BitDataGrid.ts:
- Line 741: Update the interactive-element selector in the click handling logic
to match all anchors, including those without an href, so anchor clicks are
treated as controls and do not trigger cell or row click actions; leave the
other selector entries unchanged.
- Around line 750-755: Update the shared event-dispatch path for clicks and
double-clicks to carry each event’s control classification to its handlers,
rather than updating shared state through the unawaited OnCellControlClick
interop call. Keep the correction in that shared boundary instead of duplicating
it in row and cell handlers.
