#Remarks
This method overload is used for validation types DataValidationType.Date, DataValidationType.Decimal, DataValidationType.TextLength, DataValidationType.Time, DataValidationType.WholeNumber.
Note
An individual worksheet cell can have only one data validation rule associated with it. If subsequent Add method calls affect the same cell, only the data validation rule created in the last call is applied.
#Example
Note
The maximum length of a list used to specify the Data
workbook.LoadDocument("Documents\\DataValidation.xlsx");
Worksheet worksheet = workbook.Worksheets[0];
worksheet["C1"].SetValue(DateTime.Now);
worksheet["C1"].NumberFormat = "mmm/d/yyyy h:mm";
// Restrict data entry to a whole number from 10 to 20.
worksheet.DataValidations.Add(worksheet["B1"], DataValidationType.WholeNumber, DataValidationOperator.Between, 10, 20);
// Restrict data entry to a number within limits.
DataValidation validation = worksheet.DataValidations.Add(worksheet["F4:F11"], DataValidationType.Decimal, DataValidationOperator.Between, 10, 40);
// Restrict data entry using criteria calculated by a worksheet formula.
worksheet.DataValidations.Add(worksheet["B4:B11"], DataValidationType.Custom, "=AND(ISNUMBER(B4),LEN(B4)=5)");
// Restrict data entry to 3 symbols.
worksheet.DataValidations.Add(worksheet["D4:D11"], DataValidationType.TextLength, DataValidationOperator.Equal, 3);
// Restrict data entry to values in a drop-down list specified in code.
// Note that the list in code should always use comma to separate entries,
// but the list in UI is displayed using culture-specific list separator.
worksheet.DataValidations.Add(worksheet["A4:A11"], DataValidationType.List, "PASS, FAIL");
// Restrict data entry to values in a drop-down list obtained from a worksheet.
worksheet.DataValidations.Add(worksheet["E4:E11"], DataValidationType.List, ValueObject.FromRange(worksheet["H4:H9"].GetRangeWithAbsoluteReference()));
// Restrict data entry to a time before the specified time.
worksheet.DataValidations.Add(worksheet["C1"], DataValidationType.Time, DataValidationOperator.LessThanOrEqual, DateTime.Now);
// Highlight data validation ranges.
worksheet["H4:H9"].FillColor = Color.LightGray;
int[] MyColorScheme = new int[] { 0xFFC4C4, 0xFFD9D9, 0xFFF6F6, 0xFFECEC, 0xE9D3D3, 0xFFDFC4, 0xFFDAE9};
for (int i = 0; i < worksheet.DataValidations.Count; i++){
worksheet.DataValidations[i].Range.FillColor = Color.FromArgb(MyColorScheme[i]);
}
