AX / Dynamics 365 For Finance and Operations blog

Occasionally we will need to change the accessibility of a certain controls/fields on a form in Dynamics AX. This can either be to hide/disable or show/enable the field from the user based on the current record they are on.

1. Set the target form control’s ‘AutoDeclaration’ property to ‘yes’. by default it should be false
2. Override the datasource’s active() method like shown below

[ExtensionOf(formdatasourceStr(SalesTable, SalesTable)) ]

final class SalesTable_SalesTable_DLXFormDS_Extension

{

    public int active()

    {

        int ret = next active();


        CustParameters custParm = CustParameters::find(false);

        if(custParm.OTS_EnableAutoBlockSalesOrder)

        {

            SalesTable salesTableLcl = this.cursor();



            if(salesTableLcl.M_SOMDateStatus == M_SOMDateStatusId::M_SOMConfirmed)

            {

                this.allowEdit(false);

            }

        }



       return ret;


    }

}
