Keyboard Sorting Selection Mismatch

selection-sorting-model-mismatch

Selection and sorting mechanisms fail to align because the UI component’s default keyboard-selection model cannot express column/item-based selection, and sorting rebuilds or reorders the underlying dataset, causing focus, highlights, and fixed items to drift or reset unexpectedly.

MATCHESSolution

dropdown only shows when something has been typed into the input — Similar to mantine searchable select but using shadcn. Tension: Same way you type into google searchbar before the dropdown shows. Outcome: There is a component named combo box which serves your purpose.

MATCHESSolution

Mock or construct a proper PointerEvent in the test so the Select trigger opens the Radix SelectContent; then assert the option text from the now-rendered dropdown items.

MATCHESSolution

Override the styling so the option items allow pointer events (e.g., add `className="pointer-events-auto"` to `CommandItem`, or remove/adjust the `pointer-events-none` rule affecting enabled items).

MATCHESSolution

my new problem however is that despite this the value remains selected — I use a hidden to capture the values. Tension: the inputs do actually respect the state changes. Outcome: the inputs do actually respect the state changes.

MATCHESSolution

Replace the custom components with HTML elements so the state updates work as expected

MATCHESSolution

Provide a stable unique row key via getRowId (e.g., row.id) and ensure checkbox/onClick uses the proper per-row API, such as row.toggleSelected() (invoked, not referenced). Maintain selection state with rowSelection and onRowSelectionChange to allow independent toggling per row.

MATCHESSolution

const { onChange } = useValueSelector({ listsAsArrays: true, multiple: true, handleOnChange }) — replaces the default select component with a searchable. Outcome: useValueSelector({ listsAsArrays: true, multiple: true, handleOnChange }).

MATCHESSolution

As I had the same use-case, I post my solution, built with MUI: — replaces the default select component with a searchable. Outcome: import Autocomplete from '@mui/material/Autocomplete' import TextField from '@mui/material/TextField'.

MATCHESSolution

Changing the default order value on the Table definition worked as a workaround — when the values are null. Tension: not retrieving false ('none' state). Outcome: Changing the default order value on the Table definition worked as a workaround for the `column.getNextSortingOrder()` function work as I expected.

MATCHESSolution

So the idea is to lpad the numerical identifiers with zeros, so they all contain the same amount of characters and then sort them like strings. — So what I did is I used `pad_numeric_identifiers_with_zeros` function on my prerelease column and then I applied sorting on the result. Tension: Sometimes you cannot use libraries. Outcome: I found a solution.

MATCHESSolution

Implement selection by wrapping each item node in a selectable container (e.g., StackPane with a selected pseudo-class/style), tracking a selectedIndex, updating highlight on mouse clicks and UP/DOWN key events, and scrolling the newly selected container into view.

MATCHESSolution

Subclass TKeyboardButton and override its Paint method to skip calling inherited rendering when the button State is dsPressed, then set TouchKeyboard1.DefaultButtonClass to this subclass (and rebuild by adjusting the Layout if needed) so pressed keys are not visually shown.

MATCHESSolution

Use a single ref that stores an array of item nodes (via ref callbacks) and update an index-based selection state on keydown. On arrow navigation, focus the corresponding node from the ref array (e.g., refs.current[selectedIndex].focus()).

MATCHESSolution

Remove editable: true from the checkbox column configuration and manage the checkbox state/value update yourself in the cellRenderer (e.g., via onClick and setData/updateRowData). This prevents AG Grid from switching to edit mode and keeps the checkbox centered with consistent CSS.

MATCHESSolution

the icon on the header is always pointing "up" — Sorting DOES talk to my API correctly and the records come in sorted as expected and are rendered as such. Tension: It never flips. Outcome: Add a ternary operator to your sortIcons.sorted prop.

MATCHESSolution

Bind the `Tabs` component to the correct selection handler (e.g., `onSelect={handleChange}`) and update `handleChange` to use the tab key argument so `value` updates; then conditionally render content based on `value` (or use `Tab`/`TabPane` for built-in rendering).

MATCHESSolution

Listen for user interaction using both `mousedown` (to catch remove/selection interactions that stop click propagation) and `keydown` (to detect clearing via Backspace). Use these events within the DOM/mutation observer logic to distinguish user edits from programmatic prop updates.

MATCHESSolution

One of those pages contains a MUI Select component. Tension: I can't figure away around that restriction.

MATCHESSolution

Provide a stable, unique key for each table row (and preferably for the TextField) based on the item’s identity, and update state immutably so the edited TextField component isn’t remounted during re-renders.

MATCHESSolution

Avoid in-place mutation by copying the array before sorting (e.g., `allTabs.slice().sort(...)` or `[...allTabs].sort(...)`), and derive the sorted list from the current state/selected sort option so React rerenders with the correct order.

MATCHESSolution

Use a picker component that exposes customization for the AM/PM controls (e.g., the suggested Multi Date Picker) or override the internal subcomponents via the DateTimePicker’s supported slots/theme overrides if available.

MATCHESSolution

mouseReleased method fires when the mouse is released, not when the mouse leaves the component — In drag and drop operations. Outcome: just the normal behaviour.

MATCHESSolution

Collections.sort(data, (row1, row2) -> { — Default sorting snippet. Tension: That is a "default" custom logic that will work with your items. Outcome: you may override the `compareTo` method if needed.

MATCHESSolution

newTable.setSortSupported(false); //do not sort — After you manually sorted, create a new table. Tension: do not sort. Outcome: create a new table.

MATCHESSolution

manual sorting while avoiding `table.sort()` is the best option — For codename tables. Tension: avoid deep copies, rebuild the table just once, and replace it bypassing the expensive model wrapping and UI reconstruction. Outcome: Finally, change the old table for the new one.

MATCHESSolution

Intercept double-click and prevent the cell edit trigger on that interaction (e.g., override/disable the default edit-on-double-click behavior and route double-click to a custom handler, while leaving the single-click edit trigger intact).

MATCHESSolution

Enable column selection and disable row selection with `table.setColumnSelectionAllowed(true);` and `table.setRowSelectionAllowed(false);` so built-in keyboard sorting (e.g., Ctrl+Up/Down for ascending/descending) works.

MATCHESSolution

BuildHash controls when the panel re-renders. — s&box UI uses Razor (.razor files) paired with PanelComponent. Tension: Key patterns:. Outcome: StateHasChanged();.

MATCHESSolution

Keep menu screens and in-game overlays in separate input modes. — Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled. Tension: Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled because they are actual UI scenes. Outcome: Fix pattern:.

MATCHESSolution

Fixes: for the lattice, thread filters into [REDACTED] props and add a highlight uniform, OR (if unspecified) drop the chip; for locked items, either wire onRecordFocus from the host or remove cursor:pointer/tabIndex.
