    HasValidationError Property (ColumnBase)
    In This Topic
    Gets a value indicating whether the content of one of the cells contained in the column failed the validation process.
    Syntax
    '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.
