Example

The following code example shows how to customize a CellValidator, and how to add a customized CellValidateAction. This example is part of a larger example available for the CellValidator class.

class MyRequiredFieldValidator : RequiredFieldValidator
        {
            protected override bool Validate(ValidateContext context)
            {
                if (context.EditedFormattedValue != null)
                {
                    string value = context.EditedFormattedValue.ToString();
                    if (value != "NULL")
                    {
                        context.ValidateInfo = "The input value is not NULL";
                        return false;
                    }
                    else
                    {
                        return true;
                    }
                }

                return base.Validate(context);
            }
        }
