#Remarks

Use the DataValidationCollection.Add method to create a data validation of the required type. The DataValidation.ValidationType property obtains the type of the data validation. This property is read-only, because the data validation type is specified when the data validation entry is created, and cannot be changed.

View Example

workbook.LoadDocument("Documents\\DataValidation.xlsx");
Worksheet worksheet = workbook.Worksheets[0];

// Restrict data entry to a number within limits.
DataValidation validation = worksheet.DataValidations.Add(worksheet["F4:F11"], DataValidationType.Decimal, DataValidationOperator.Between, 10, 40);

// Change the validation operator and criteria.
// Range F4:F11 should contain numbers greater than or equal 20.
validation.Operator = DataValidationOperator.GreaterThanOrEqual;
validation.Criteria = 20;
validation.Criteria2 = ValueObject.Empty;

// Highlight data validation ranges.
int[] MyColorScheme = new int[] { 0xFFC4C4, 0xFFD9D9, 0xFFF6F6, 0xFFECEC, 0xE9D3D3 };
for (int i = 0; i < worksheet.DataValidations.Count; i++)
{
    worksheet.DataValidations[i].Range.FillColor = Color.FromArgb(MyColorScheme[i]);
