Add data validation
func (f *File) AddDataValidation(sheet string, dv *DataValidation)
AddDataValidation provides set data validation on a range of the worksheet by given data validation object and worksheet name. The data validation object can be created by NewDataValidation function. Data validation type and operators can be found in the Constants section.
Example 1, set data validation on Sheet1!A1:B2 with validation criteria settings, show error alert after invalid data is entered with "Stop" style and custom title "error body":
dv := excelize.NewDataValidation(true)
dv.SetSqref("A1:B2")
dv.SetRange(10, 20, excelize.DataValidationTypeWhole, excelize.DataValidationOperatorBetween)
dv.SetError(excelize.DataValidationErrorStyleStop, "error title", "error body")
f.AddDataValidation("Sheet1", dv)
Example 2, set data validation on Sheet1!A3:B4 with validation criteria settings, and show input message when cell is selected:
dv = excelize.NewDataValidation(true)
dv.SetSqref("A3:B4")
dv.SetRange(10, 20, excelize.DataValidationTypeWhole, excelize.DataValidationOperatorGreaterThan)
dv.SetInput("input title", "input body")
f.AddDataValidation("Sheet1", dv)
Example 3, set data validation on Sheet1!A5:B6 with validation criteria settings, create in-cell dropdown by allowing list source:
dv = excelize.NewDataValidation(true)
dv.SetSqref("A5:B6")
dv.SetDropList([]string{"1", "2", "3"})
f.AddDataValidation("Sheet1", dv)
Example 4，set data validation on Sheet1!A7:B8 with validation criteria source Sheet1!E1:E3 settings, create in-cell dropdown by allowing list source:
dv := excelize.NewDataValidation(true)
dv.SetSqref("A7:B8")
dv.SetSqrefDropList("$E$1:$E$3")
f.AddDataValidation("Sheet1", dv)
Get data validations
func (f *File) GetDataValidations(sheet string) ([]*DataValidation, error)
GetDataValidations returns data validations list by given worksheet name.
Delete data validation
func (f *File) DeleteDataValidation(sheet string, sqref ...string) error
DeleteDataValidation delete data validation by given worksheet name and reference sequence. All data validations in the worksheet will be deleted if not specify reference sequence parameter.
