CellErrorStyle Property (Cell)

Gets or sets the style that will be used by the cell when its content fails the validation process.

Syntax

Visual Basic
C#

public Style CellErrorStyle {get; set;}

'Declaration
 
Public Property CellErrorStyle As Style

'Usage
 
Dim instance As Cell
Dim value As Style
 
instance.CellErrorStyle = value
 
value = instance.CellErrorStyle

Property Value

The style that will be used by the cell when its content fails the validation process. By default, a null reference (Nothing in Visual Basic).

Remarks

When the value of a cell fails the validation process, its HasValidationError property will return true and its ValidationError property will contain a CellValidationError, which provides information on the cell in error, the error content, the exception (if one was thrown), and the validation rule that failed. If the validation rule that failed is a binding-level ValidationRule, it will be wrapped in a PassthroughCellValidationRule. Validation errors will also be reported by a row when the value of one or more of its cells fails the validation process. Like cells, when a row contains validation errors, its HasValidationError property will return true and its ValidationError property will contain a RowValidationError, which provides information on the row in error, the error content, the exception, and the validation rule that failed.
