Syntax

Visual Basic
C#

'Declaration
 
Public Event ValidationError As System.EventHandler(Of ValidationErrorEventArgs)

'Usage
 
Dim instance As GcSpreadSheet
Dim handler As System.EventHandler(Of ValidationErrorEventArgs)
 
AddHandler instance.ValidationError, handler

public event System.EventHandler<ValidationErrorEventArgs> ValidationError

Event Data

The event handler receives an argument of type ValidationErrorEventArgs containing data related to this event. The following ValidationErrorEventArgs properties provide information specific to this event.

Property	Description
Column	Gets the column index.
Row	Gets the row index.
ValidationResult	Gets or sets the policy that the user can set to determine how to process the error.
Validator	Gets the validator which caused this error. This validator is a copy of the real validator, so any modifications to this validator do not take effect.

Example

This example uses the ValidationError event. The event occurs if the typed data is less than three characters or greater than five.

gcSpreadSheet1.ActiveSheet[1, 1, 3, 3].DataValidator = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateTextLengthValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.Between, 3, 5);
private void gcSpreadSheet1_ValidationError(object sender, GrapeCity.Windows.SpreadSheet.UI.ValidationErrorEventArgs e)
        {
            listBox1.Items.Add(e.Column.ToString());
            listBox1.Items.Add(e.Row.ToString());
            listBox1.Items.Add(e.ValidationResult.ToString());
            listBox1.Items.Add(e.Validator.ToString());
            e.ValidationResult = GrapeCity.Windows.SpreadSheet.UI.UndoRedo.DataValidationResult.Discard;
        }

        private void gcSpreadSheet1_ValueChanged(object sender, GrapeCity.Windows.SpreadSheet.UI.CellEventArgs e)
        {
            listBox1.Items.Add(e.Column.ToString());
            listBox1.Items.Add(e.Row.ToString());
        }

VB.NET

GcSpreadSheet1.ActiveSheet(1, 1, 3, 3).DataValidator = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateTextLengthValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.Between, 3, 5)

Private Sub GcSpreadSheet1_ValidationError(sender As System.Object, e As GrapeCity.Windows.SpreadSheet.UI.ValidationErrorEventArgs) Handles GcSpreadSheet1.ValidationError
        ListBox1.Items.Add(e.Column.ToString())
        ListBox1.Items.Add(e.Row.ToString())
        ListBox1.Items.Add(e.ValidationResult.ToString())
        ListBox1.Items.Add(e.Validator.ToString())
        e.ValidationResult = GrapeCity.Windows.SpreadSheet.UI.UndoRedo.DataValidationResult.Discard
    End Sub

Private Sub GcSpreadSheet1_ValueChanged(sender As System.Object, e As GrapeCity.Windows.SpreadSheet.UI.CellEventArgs) Handles GcSpreadSheet1.ValueChanged
        ListBox1.Items.Add(e.Column.ToString())
        ListBox1.Items.Add(e.Row.ToString())
    End Sub
