Wide grids

GridControl

Twenty-one columns and a thousand rows: pinned edges, and only the columns in view kept in the page.

Overview

EnableColumnVirtualization renders only the non-frozen columns that are horizontally in view, plus ColumnVirtualizationOverscan columns on either side; the rest become fixed-width spacers so the scrollbar and the column positions stay right. Frozen columns stay mounted. The grid exposes ColumnVirtualizationStatus (Disabled, Active or Fallback) and, when it has to fall back to a full render, ColumnVirtualizationFallbackReason. WidthMode="GridWidthMode.FitColumns" sizes the grid to the sum of its column widths, up to the space available.

Examples

#Twenty-one columns, three of them pinned

Scroll the grid sideways. ID and Code stay on the left, Status on the right, and the eighteen metric columns move between them. The first paint mounts every column; from the first scroll on, only the metrics in view plus two on each side stay mounted and the rest become spacers. The line under the grid reports the grid's own status.

Column virtualization: Fallback (there are no scrollable columns to virtualize)

Documentation

GridControl parameters

Parameter	Type	Default	Description
`EnableColumnVirtualization`	`bool`	`false`	Mounts only the non-frozen columns that are horizontally in view, plus the overscan on each side; the omitted width becomes a spacer so column positions and the scrollbar stay right. Frozen columns always stay mounted. The first paint after mount renders every column because the viewport is not measured yet; the window applies once the scroll area has reported its size. Flat tables only: the fallback reasons below list what turns it off.
`ColumnVirtualizationOverscan`	`int`	`2`	Extra scrollable columns kept mounted before and after the visible range. A negative value counts as zero.
`ColumnVirtualizationDefaultWidth`	`double`	`0`	Width assumed for a column that declares no `Width` and has not been resized. At zero such a column makes the grid fall back to a full render.
`ShowColumnVirtualizationFallback`	`bool`	`true`	Shows a one-line note, "Columns: full render (reason)", when virtualization is on but the current layout cannot be windowed.
`WidthMode`	`GridWidthMode`	`GridWidthMode.FillAvailable`	`FillAvailable` keeps the table at least as wide as the grid's host. `FitColumns` sizes host and table to the sum of the visible column widths, up to the parent's width.

Read-only status on GridControl

Property	Type	Default	Description
`ColumnVirtualizationStatus`	`GridColumnVirtualizationStatus`	—	`Disabled` when the flag is off, `Active` when the current layout can be windowed, `Fallback` when it cannot. Computed on each read.
`ColumnVirtualizationFallbackReason`	`string?`	—	Why the grid renders every column; null when disabled or active. Reasons: a pivot or chart view; grouped rows; an inline row edit in progress; header bands; a `RowTemplate`; stacked or adaptive layout; no scrollable column (all frozen); a column whose `Width`, `MinWidth` or `MaxWidth` is not a pixel value, or that has no width and no default width.

CSS classes and data attributes

Class	Effect
`data-fx-column-virtualization`	On the grid's root element: `disabled`, `active` or `fallback`.
`data-fx-column-virtualization-fallback`	On the root element: the fallback reason, empty otherwise.
`fx-column-window-spacer-col / fx-column-window-spacer`	The `<col>` and the header, filter, body and aggregate cells that stand in for the omitted columns' width.
`fx-grid-column-virtualization-fallback`	The fallback note: one grey 9px line with `role="status"` and the reason in its tooltip.

Whether a column can be windowed is decided by its own Width, MinWidth and MaxWidth: a pixel value (120px or a bare 120) counts, anything else does not; a column the user has resized keeps that width. The scroll area reports its position and width through the grid's script, and the grid re-renders only when the set of mounted columns changes.
