DataValidation.Criteria Property

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

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

C#

ValueObject Criteria { get; set; }

VB.NET

Property Criteria As ValueObject

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.

DataValidationActions.cs

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]);
}

DataValidationActions.vb

workbook.LoadDocument("Documents\DataValidation.xlsx")
Dim worksheet As Worksheet = workbook.Worksheets(0)

' Restrict data entry to a number within limits.
Dim validation As DataValidation = 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

' Highlight data validation ranges.
Dim MyColorScheme() As Integer = { &HFFC4C4, &HFFD9D9, &HFFF6F6, &HFFECEC, &HE9D3D3 }
For i As Integer = 0 To worksheet.DataValidations.Count - 1
    worksheet.DataValidations(i).Range.FillColor = Color.FromArgb(MyColorScheme(i))
Next i
