FAQ

01. Why when click Compile Script button prompt error [Error] (xx:xx):Unknown identifier 'Dataset'

This happen if you doing script on the event OnGridColumnValueChanged & can ignore the error if you confirm your script is correct.

02. How do I know my script is correct when using the script on the event OnGridColumnValueChanged ?

You can add below script at 1st line before you click Compile Script button but remember to remove it before you click Save button.
var EditingField, Dataset :Variant;

03. How many data source (TDatasource) it had for data entry (eg Sales Invoice) & what is each name?

Generally it had 3 data source & some had extra 1 (i.e. total 4).
Below is the list & detail
DataSource Name Description
dsGrid Data shown in Grid(Read Only mode) Before Click Detail Button
dsDocMaster Header Data
dsDocDetail Item Grid(Detail) Data
dsSerialNumber Selected Item Code Serial Number in the Item Grid(Detail) Data

04. How to check the Record in Edit Mode?

You can use below script
var AState : TDataSetState;
    M      : TDataSource;
begin
  M := TDataSource(Self.FindComponent('dsDocMaster'));
  AState := M.DataSet.State;
  if (AState = dsInsert) or (AState = dsEdit)  then begin // Check is in Insert or Edit Mode
    MessageDlg('Yes In Edit Mode', mtInformation, [mbOK], 0);
  end;
end;
