Introduction

This is Additional Module(DIY Script Module) which allow user to override or customise the SQL System.
The Language use is Pascal

DIY Script

Available Action/Event

Action/Event Description
OnOpen The script trigger On Open the Form (eg On Open the Sales Invoice Form)
OnClose The script trigger On Close/Exit the Form (eg on Exit Sales Invoice Form)
OnBeforeNew The script trigger before the build in New Button action execute.
OnAfterNew The script trigger after the build in New Button action Execute.
OnBeforeEdit The script trigger before the build in Edit Button action execute.
OnAfterEdit The script trigger after the build in Edit Button action Execute.
OnBeforeDelete The script trigger before the build in Delete Button action execute.
OnAfterDelete The script trigger after the build in Delete Button action Execute.
OnBeforeSave The script trigger before the build in Save Button action execute.
OnAfterSave The script trigger after the build in Save Button action Execute.
OnBeforeCancel The script trigger before the build in Cancel Button action execute.
OnAfterCancel The script trigger after the build in Cancel Button action Execute.
OnBeforePrint The script trigger before the build in Print or Preview Button action Execute.
OnGridBeforeInsert The script trigger before the build in + Button action Execute.
OnGridAfterInsert The script trigger after the build in + Button action Execute.
OnGridBeforePost The script trigger before post the current row record.
OnGridAfterPost The script trigger after post the current row record.
OnGridBeforeDelete The script trigger before the build in - Button action Execute.
OnGridAfteDelete The script trigger after the build in - Button action Execute.
OnGridBeforeCancel The script trigger before cancel the current row record.
OnGridAfterCancel The script trigger after cancel the current row record.
OnGridColumnValueChanged The script trigger on changes value in the current record.
Template.Tips-01.jpg
Commonly we only OnOpen, OnBeforeSave & OnGridColumnValueChanged Event
Template.Warning-01.jpg
Avoid use 2 same Event/Action in 1 Business Object (eg 2 OnOpen in Sales Invoice is NOT allow)

Example 1 - Get UDF & Do Calculation

Below is Example are doing following actions

  • Get UDF_Length & UDF_Width from Maintain Item UDF Fields
