Enable or disable a field on a forms grid based on another field value in Dynamics AX

How can we disable and enable fields on a X++ form Dynamics AX ?

enter image description here

Field1 is an enum with option option1 and option2.

We have below scenarios:

  1. If Field1 is option1 then Field2 field should be enabled and Field3 field should be disabled/readonly

  2. If Field1 is option2 then Field3 field should be enabled and Field2 should be disabled/readonly

3/ Also, when the form loads, for the existing records the Field3 and Field2 fields should be enabled/readonly based on their current value for Field1

You can override method active() on the form's datasource, something like

public int active()
{
    FormDataSource fds;
    int ret;

    ret = super();

    fds = this.dataSource();

    fds.object(fieldNum(MyTableName, Field2)).allowEdit(MyDataSourceName.Field1 == option1);
    fds.object(fieldNum(MyTableName, Field3)).allowEdit(MyDataSourceName.Field1 == option2);
    
    return ret;
}

That's good enough if Field1 value cannot be modifed by the user. If it can be modified then it makes sense to create a new method e.g. setFieldAccess() with the logic similar to the above, and call this new method both from the datasource active() method and from the modified() method of the datasource field Field1.
