DataValidation.Criteria Property

Gets or sets the value used in the criterion for the data validation.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v21.1.Core.dll

Declaration

ValueObject Criteria { get; set; }

Property Value

Type Description
ValueObject

A ValueObject instance.

Remarks

The Criteria value is used as one of the bounds for DataValidationOperator.Between and DataValidationOperator.NotBetween operators, and the only value or formula used for other DataValidationOperator types, or for DataValidationType.Custom or DataValidationType.List type data validation.

The content specified by the Criteria property can be a formula, a constant, a worksheet cell or range, or a list series (comma separated values).

Since the ValueObject class provides implicit constructors for most types, you can assign a numerical, text, boolean or DateTime value directly to the Criteria property. For the worksheet range or formula, use the ValueObject.FromRange or ValueObject.FromFormula methods, respectively.

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]);
}
