SetLowerConstraint(DateTime) Method

Sets the lower constraint value used to validate the cell value.

Syntax

C#

public void SetLowerConstraint( 
   DateTime value
)

Parameters

value

The lower constraint value used to compare against the cell value.

Exceptions

Exception	Description
System.ArgumentException	Occurs when value cannot be represented as a date in Excel.
System.ArgumentException	Occurs when the specified value is greater than the upper constraint value. If the upper constraint formula does not equal a constant, this verification is not performed.

Remarks

The way in which the cell value is compared to the lower constraint value is determined by the ValidationOperator as well as the ValueConstraintDataValidationRule.ValidationCriteria.

Depending on the ValidationCriteria of the rule, either the cell value itself or the length of the cell value's text equivalent is compared to the lower constraint value.

When the ValidationOperator is Between, the value must be greater than or equal to the lower constraint and less than or equal to the upper constraint. When the ValidationOperator is NotBetween, the value must be less than the lower constraint or greater than the upper constraint.

This overload is preferred when the ValidationCriteria is Date. When the ValidationCriteria is WholeNumber, Decimal, or TextLength, the SetLowerConstraint(Double) overload is preferred, and when the ValidationCriteria is Time, the SetLowerConstraint(TimeSpan) overload is preferred.
