GetValidate

Description

Obtains the validation rule for a column in a DataWindow.

Applies to

DataWindow type	Method applies to
PowerBuilder	DataWindow control, DataWindowChild object, DataStore object

Syntax

PowerBuilder

string dwcontrol.GetValidate ( string column )
string dwcontrol.GetValidate ( integer column )

1 2	string dwcontrol.GetValidate ( string column ) string dwcontrol.GetValidate ( integer column )

Argument	Description
dwcontrol	A reference to a DataWindow control, DataStore, or child DataWindow.
column	The column for which you want the validation rule. Column can be a column number or a column name. The column number is the number of the column as it is listed in the Column Specification view of the DataWindow painter — not necessarily the number of the column in the Design view.

Return value

Returns the validation rule for column in dwcontrol. Returns the
empty string (“”) if no validation criteria are defined for the
column.

If any argument value is null, in PowerBuilder and JavaScript the
method returns null.

Usage

You can use GetValidate to save the current validation rule before
calling SetValidate to change the rule temporarily.

Examples

These statements change the validation rule for column 7 in the
DataWindow control dw_Employee to Rule2:

string Rule1, Rule2 = "Long(GetText()) &gt; 15000"
Rule1 = dw_Employee.GetValidate(7)
dw_Employee.SetValidate(7, Rule2)

string Rule1, Rule2 = "Long(GetText()) > 15000"

Rule1 = dw_Employee.GetValidate(7)

dw_Employee.SetValidate(7, Rule2)
