Limitations

The following table lists known GridControl limitations according to the WCAG 2.x standard:

WCAG 2.x Criterion	Exception Description
1.3.1 Info and Relationships (Level A)	When a user selects a cell, the GridControl does not provide assistive technologies with accessible information about the corresponding column header title. TreeListView does not provide assistive technologies with accessible information about the selected node’s level.
2.1.1 Keyboard (Level A)	The following keyboard operations are unavailable: Search Panel: navigate to the Next, Previous, and Hide buttons. Conditional Formatting Manager: focus two first columns. Master Detail/TreeListView: focus Expand Row/Node buttons. As a workaround you can use Ctrl + +/- key combinations to expand/collapse rows/nodes. Master Detail: Switch between tabs. Navigate to a content detail descriptor view. Filter Panel: interact with Hide Panel and Edit Filter buttons. Column Chooser: Focus elements. Reorder columns. As a workaround, you can use the GridColumn.VisibleIndex property to implement custom logic for column reorder operations. Filter Editor: navigate to +/Delete buttons. Card View: expand/collapse cards. Auto Filter Row: navigate to a filter criterion. Paged Source: use navigation buttons. As a workaround, you can use the PagedSourceBase.PageIndex property to select a page. Column Headers: focus a column header. As a workaround, you can call GridControl.SortBy, GridControl.GroupBy, TableView.ShowFilterEditor methods on a key press event. Fixed Rows: change a row’s fixed state. As a workaround, you can call the TableView.FixRow method on a key press event. Compact Mode: focus Filter/Sort buttons. As a workaround, you can call GridControl.SortBy and GridControl.GroupBy methods on a key press event.
2.1.2 No Keyboard Trap (Level A)	Users need to press Ctrl+Tab to move focus away from the GridControl.
2.5.3 Label in Name (Level A 2.1 only)	The list below outlines GridControl‘s elements that do not provide assistive technologies with accessible information: Column Drop-down Filter: The focused filter value. The editor that contains the filter condition. Tab item text. New Item Row: the label. Filter Editor: labels of filter elements.
4.1.2 Name, Role, Value (Level A)	The list below outlines GridControl‘s elements that do not provide assistive technologies with accessible information: Row Selection Mode: Selected row value(s). Master Detail: Changes of the master element’s state (expanded/collapsed). First row’s label, if you focus it after a master row. Column Drop-down Filter: Filter value state changes (checked/unchecked). The All filter value (wrong label). TreeListView: Element state changes (expanded/collapsed). Node state changes (checked/unchecked). Focused node. EditEntireRow mode: button label. Content within CellTemplate, RowDetailsTemplate, and DataRowCompactTemplate. Cell selection state when it’s changed by the Space key. Selected row index and the total number of rows when you focus a row. Group and master row state changes (expanded/collapsed). Editor type in the active cell. Changes of cell values made via GridControl APIs. Sparkline value displayed within a cell.
2.5.7 Dragging Movements (Level AA 2.2 only)	DevExpress GridControl meets the specified criterion with the following exceptions: Column resizing Column reordering Row drag & drop (when enabled)
2.5.8 Target Size (Minimum) (Level AA 2.2 only)	GridColumn resizing splitters and filter buttons may contain smaller pointer input arears than 24x24 pixels (depending on the applied theme).

Note

Accessibility features of your application depend on implementation (your use of GridControl API). Your application may not require or enable user actions listed above. The limitation list may also be incomplete. Test all required user functionality to ensure accessibility compliance.
