Gets or sets the criteria to use when validating the cell value against the constraint(s).
Depending on the value specified, either then cell value or the length of its text equivalent will be compared against the constraint(s). In addition, certain ValidationCriteria values may disallow a cell value even if it is valid when compared to the constraint. For example, the ValidationCriteria.WholeNumber value will not allow any number with a fractional portion.
[[InvalidEnumArgumentException]] Occurs when the value is not a member of the [[DataValidationCriteria]] enumeration.
Gets or sets the validation operator to use when comparing the cell value against the constraint value or formula.
Depending on the [[ValueConstraintDataValidationRule.validationCriteria]] of the rule, either the cell value itself or the length of the cell value's text equivalent is compared to the constraint value or formula.

Creates a copy of this rule which can be applied to other worksheets.
Gets the constraint formula used to validate the cell value.
The way in which the cell value is compared to the constraint formula's 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 constraint formula's value.
The address passed in is only needed if relative addresses are used in the the formula. For example, consider the formula applied is =B1, and the data validation rule is applied to the region A1:A5. If you get the formula for A1, the formula =B1 will be returned. If you get the formula for A2, =B2 will be returned. Similarly, for cell A5, =B5 will be returned. However, if the formula contains no references or all absolute references, the 'address' is ignored. So in the previous example, if the original formula was =$B$1, the same formula will be returned regardless of the specified address.
'address' can be any valid cell or region reference on a worksheet. If a region address is specified, the top-left cell or the region is used. The cell or region specified does not need to have the data validation rule applied to it. Any reference is allowed.
The cell reference mode with which to parse 'address' will be assumed to be A1, unless the data validation rule is applied to a worksheet which is in a workbook, in which case the [[Workbook.cellReferenceMode]] will be used.
[[ArgumentException]] Occurs when 'address' is not a valid cell or regions address.
The address of the cell or region that serves as the basis for relative references, or null to use the top-left cell of the worksheet.
Gets the constraint formula used to validate the cell value.
The way in which the cell value is compared to the constraint formula's value is determined by the [[validationOperator]] as well as the [[ValueConstraintDataValidationRule.validationCriteria]].

The address passed in is only needed if relative addresses are used in the the formula. When the data validation rule is applied to cells or regions, the references in the formula used by each individual cell will be shifted by the offset of the cell to the passed in 'address'. For example, consider the formula specified is =B1 and the specified address is A1. If the data validation rule is then applied to the A5 cell, the formula is will use is =B5. However, if the references in the formula are absolute, such as =$B$1, the same formula will be applied regardless of the specified address.
'address' can be any valid cell or region reference on a worksheet. If a region address is specified, the top-left cell or the region is used. The cell or region specified does not need to have the data validation rule applied to it. Any reference is allowed.
