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)	In Master-Detail mode, a detail tab does not provide assistive technologies with accessible information about other tabs. Exported documents do not preserve information about the table structure. Dialog Edit Form: editors do not provide assistive technologies with accessible information about their labels. Kanban View does not provide assistive technologies with accessible information about labels in the focused column.

4.1.2 Name, Role, Value (Level A)	The list below contains the GridControl‘s accessible information that is not provided for assistive technologies: Group row’s expanded/collapsed state changes. Specified criterion in the AutoFilterRow. Group row value when a user navigates from a master row to a detail grid’s group row. Grid values that are changed via APIs. Values within the NewItemRow/AutoFilterRow. Fields in the Card and Layout View cards when a user navigates through them without editing. In the WinExplorer View, focused group row.
2.5.7 Dragging Movements (Level AA 2.2 only)	DevExpress GridControl meets the specified criterion with the following exceptions: Column resize Column reorder 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 areas than 24x24 pixels depending on the applied theme.
4.1.3 Status Messages (Level AA 2.1 only)	DevExpress WinForms GridControl does not inform assistive technologies when a value changes in the GridControl’s find panel.
