The following code snippet adds a new data validation rule and customizes the error dialog invoked when validation fails for the user’s input.
The customized dialog is shown in the image below.
workbook.LoadDocument("Documents\\DataValidation.xlsx");
Worksheet worksheet = workbook.Worksheets[0];
// Restrict data entry to a 5-digit number.
DataValidation validation = worksheet.DataValidations.Add(worksheet["B4:B11"], DataValidationType.Custom, "=AND(ISNUMBER(B4),LEN(B4)=5)");
// Show error message.
validation.ErrorTitle = "Wrong Employee Id";
validation.ErrorMessage = "The value you entered is not valid. Use 5-digit number for the employee ID.";
validation.ErrorStyle = DataValidationErrorStyle.Information;
validation.ShowErrorMessage = true;
// 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]);
}
workbook.LoadDocument("Documents\DataValidation.xlsx")
Dim worksheet As Worksheet = workbook.Worksheets(0)
' Restrict data entry to a 5-digit number.

validation.ErrorMessage = "The value you entered is not valid. Use 5-digit number for the employee ID."
validation.ErrorStyle = DataValidationErrorStyle.Information

For i As Integer = 0 To worksheet.DataValidations.Count - 1
worksheet.DataValidations(i).Range.FillColor = Color.FromArgb(MyColorScheme(i))
Next i
