Member of Spin Edit (PRIM_MD.SpinEdit)

Parameters

Details

The Validate method allows for the use of table and field rules to be used for Spin Edit Fields in the Visual LANSA Web runtime.

Validate operation allows for the validation usage on insert, update and deletion.

If valid is returned as false the field property HasError will be set to true.

Validating against a LANSA table requires the table name to be prefixed with '#'.

Complex logic and look up rules are not implemented for use in the validate method.

Example

This example shows the validating xAccidentAssessmentNumber against the xAccident table for insert, update and deletion.
    
xAccidentAssessmentNumber uses a range check to validate values of the field must fall between (1 to 9999999999999).
