HasValidationError Property (ColumnBase)

Gets a value indicating whether the content of one of the cells contained in the column failed the validation process.

Syntax

Visual Basic
C#

'Declaration
 
Public ReadOnly Property HasValidationError As Boolean

'Usage
 
Dim instance As ColumnBase
Dim value As Boolean
 
value = instance.HasValidationError

public bool HasValidationError {get;}

Property Value

true if the content of one of the cells contained in the column has failed the validation process; false otherwise. By default, false.

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.
