Adding a new datasource to a form

Posted on by 700

Hi community,

I have a question how to add a new data source to a standard ax form with relations to the exisiting data sources.

I have a form with a standard template that have one main datasource and three other data sources. I need to add a datasource that is connected to one of the three tables and not the main table. I miss setting a relationship like we do in a query. Where can I look up an example to do it? 

Can I add a datasource only setting properties or do I need to set relations between two tables in code?

Thank you all

    Thanks for suggestions. I tried it but I need to add a datasource that will be linked to the second data source.

    For suppose if you have TableA(parentTable) and TableB(ChildTable). If both tables have relation defined at the table level, then you set properties JoinSource and LinkType on TableB. If their is no pre-defined relation/relate based on other condition, then you can make use of addLink method.In the init method of TableB include following code:

    public void init()
        QueryBuildDataSource qbds;
        qbds = this.query().dataSourceTable(tableNum(TableB));
        qbds.addLink(fieldNum(TableA, CommonField), fieldNum(TableB, CommonField));

    Refer below link:
