setFormula1(formula, isR1C1, isLocal)
Sets the value or expression associated with this validation.

|---|---|---|
| formula | String | The value or expression associated with this format condition. |
| isR1C1 | boolean | Whether the formula is R1C1 formula. |

getListValue(row, column)
Get the value for list of the validation for the specified cell.
Only for validation whose type is List and has been applied to given cell, otherwise null will be returned.
| Parameter | Type | Description |
|---|---|---|
| row | int | The row index. |
| column | int | The column index. |
Returns: The value to produce the list of this validation for the specified cell. If the list references to a range, then the returned value will be a ReferredArea object; Otherwise the returned value may be null, object[], or simple object.

addArea(cellArea) (1 of 2)
Applies the validation to the area.
It is equivalent to use addArea(com.aspose.cells.CellArea, boolean, boolean) with checking intersection and edge.
| Parameter | Type | Description |
|---|---|---|
| cellArea | CellArea | The area. |
addArea(cellArea, checkIntersection, checkEdge) (2 of 2)
Applies the validation to the area.
In this method, we will remove all old validations in given area. For the top-left one of Validation’s applied ranges, firstly its StartRow is smallest, secondly its StartColumn is the smallest one of those areas who have the same smallest StartRow.
| Parameter | Type | Description |
|---|---|---|
| cellArea | CellArea | The area. |
| checkIntersection | boolean | Whether check the intersection of given area with existing validations’ areas. If one validation has been applied in given area(or part of it), then the existing validation should be removed at first from given area. Otherwise corruption may be caused for the generated Validations. If user is sure that the added area does not intersect with any existing area, this parameter can be set as false for performance consideration. |
| checkEdge | boolean | Whether check the edge of this validation’s applied areas. Validation’s internal settings depend on the top-left one of its applied ranges, so if given area will become the new top-left one of the applied ranges, the internal settings should be changed and rebuilt, otherwise unexpected result may be caused. If user is sure that the added area is not the top-left one, this parameter can be set as false for performance consideration. |
addAreas(areas, checkIntersection, checkEdge)
Applies the validation to given areas.
In this method, we will remove all old validations in given area. For the top-left one of Validation’s applied ranges, firstly its StartRow is smallest, secondly its StartColumn is the smallest one of those areas who have the same smallest StartRow.
| Parameter | Type | Description |
|---|---|---|
| areas | CellArea[] | The areas. |
| checkIntersection | boolean | Whether check the intersection of given area with existing validations’ areas. If one validation has been applied in given area(or part of it), then the existing validation should be removed at first from given area. Otherwise corruption may be caused for the generated Validations. If user is sure that all the added areas do not intersect with any existing area, this parameter can be set as false for performance consideration. |
| checkEdge | boolean | Whether check the edge of this validation’s applied areas. Validation’s internal settings depend on the top-left one of its applied ranges, so if one of given areas will become the new top-left one of the applied ranges, the internal settings should be changed and rebuilt, otherwise unexpected result may be caused. If user is sure that no one of those added areas is the top-left, this parameter can be set as false for performance consideration. |
