Property Value

Type Description

true to display errors within cells that fail validation specified by the Data Annotations attribute(s); otherwise, false.


The WPF Grid and TreeList controls support DataAnnotations attributes that specify data validation rules (to use data annotation attributes, reference the System.ComponentModel.DataAnnotations assembly).

By default, the grid (or treelist) displays error icons (ErrorIcon_Critical) within cells with invalid values, and provides error descriptions displayed as tooltips (see the image below). In this instance, the cell focus cannot be moved to another cell until the cell’s value is corrected.

To override the default behavior and hide errors, set the ShowValidationAttributeErrors property to false. To override the default behavior for individual columns, use the ColumnBase.ShowValidationAttributeErrors property.
