Cannot find the definition for the datasource variable

Posted on by Community Member

Hi There,

I'm learning the Dynamics AX 2012 programming at the moment, suppose i drag a Table(MainAccount) to the Form's datasources.

i can reference the dataTable in the X++ codes by using "MainAccount_ds", or the query like this "MainAccount_q". from my point of view, there are pre-defined object reference for the datasource.

Where i can find all the pre-defined variables for the datasource ?

many thanks.

    Hi,

    Interesting, I didn't know about myTable_q.

    Nonetheless, the two important ones would be myTable and myTable_ds. As mentioned here msdn.microsoft.com/.../aa636676.aspx

    Then you can use the datasource methods to do other things, like myTable_ds.query() to get the query.

    P.S. No, I haven't seen any reference for a list of the references you looking for.

    you can find all the system pre-defined variables for the datasource and form object

    if you put a breakpoint in init() method of the form and look into variable windows in debugger

    where as for datasource we have

    TableName_ds - datasource object

    TableName_q - datasource query object

    TableName_QR - Datasource queryRun object

    Please verify and update if this information helps you.
