This form can be used to add, edit, and remove data validation for a cell or a range of cells. To use the form, create an instance of the ValidationForm class, by providing the related workbook and the initial IValidation object, and call the ShowDialog method. To apply the changes made through the form, call the Apply method. The following image shows the form:
