Property Value

The style that will be used by the cells contained in the column when their content fails the validation process. By default, a null reference (Nothing in Visual Basic).
Example
All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
The following example demonstrates how to provide a new style that will change the foreground color of a cell when its value fails the validation process. It uses the ShippingCostValidationRule custom validation rule defined in the previous example.
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"
