Example

The following code example uses the CompareValueValidator to validate whether the original value is greater than 10. When you enter edit mode, input a value, press the Enter key to end the edit, and then press the Esc key to trigger the CancelRow, a system sound plays to notify you that the validation failed. This example is part of a larger example available for the CellValidator class.

void setCompareValueValidator_Click(object sender, EventArgs e)
        {
            Template template = Template.CreateGridTemplate(1);

            CompareValueValidator compareValueValidator = new CompareValueValidator();
            //Set the RequiredType first, then set other properties.
            compareValueValidator.RequiredType = typeof(int);
            compareValueValidator.ComparedValue = 10;
            compareValueValidator.DifferenceValue = 0;
            compareValueValidator.ComparedOperator = ValidateComparisonOperator.GreaterThan;
            

            SoundNotify soundNotify = new SoundNotify();
            soundNotify.SoundType = SystemSoundType.Asterisk;
            //When cancelling the entire row's editing, the old value is restored.
            soundNotify.DoActionReason = ValidateReasons.CancelRow;

            compareValueValidator.Actions.Add(soundNotify);

            //When using the SoundNotify action, the value 9 is validated.
            template.Row.Cells[0].Value = 9;
            template.Row.Cells[0].Validators.Add(compareValueValidator);

            this.gcMultiRow1.Template = template;
            label.Text = "The CompareValueValidator.ComparedValue is 10, DifferenceValue is 0, ComparedOperator is GreaterThan, input a value in the Cell, press ENTER to commit the value (not validate), then press ESC to trigger validation (DoActionReason is CancelRow), the old value 9 is restored and validated, validation fails, a sound is played";
        }

VB.NET

        Dim template As Template = template.CreateGridTemplate(1)

        Dim compareValueValidator As New CompareValueValidator()
        'Set the RequiredType first, then set other properties.
        compareValueValidator.RequiredType = GetType(Integer)
        compareValueValidator.ComparedValue = 10
        compareValueValidator.DifferenceValue = 0
        compareValueValidator.ComparedOperator = ValidateComparisonOperator.GreaterThan


        Dim soundNotify As New SoundNotify()
        soundNotify.SoundType = SystemSoundType.Asterisk
        'When cancelling the entire row's editing, the old value is restored.
        soundNotify.DoActionReason = ValidateReasons.CancelRow

        compareValueValidator.Actions.Add(soundNotify)

        'When using the SoundNotify action, the value 9 is validated.
        template.Row.Cells(0).Value = 9
        template.Row.Cells(0).Validators.Add(compareValueValidator)

        Me.gcMultiRow1.Template = template
        label.Text = "The CompareValueValidator.ComparedValue is 10, DifferenceValue is 0, ComparedOperator is GreaterThan, input a value in the cell, press ENTER to commit value (not validate), then press ESC to trigger validation (DoActionReason is CancelRow), the old value 9 is restored and validated, validation fails, a sound is played"
