Find Root Caller Form

Recently I faced the situation where I want the root caller form name from the ladder of forms opened one after one, from each other. And for that I didn’t find any solution on internet so mind clicked and made one solution for that. Hope it’s useful.

We have FORM-A and FORM-B, FORM-A is root form means FORM-B is opened from FORM-A, and FORM-B opened FORM-B again and again.

In above scenario, if we need the root caller name then we have to implement the below logic,

1. You have to make one parm method in the FORM-B for caller form like below
   

   IdentifierName parmCallerName(IdentifierName  _callerName = callerName)
   {
       callerName = _callerName;
       return callerName;
   }
   

2. Now add below logic into the init method of FORM-B
   

   if (element.args().caller() && element.args().caller().name() == formStr(A))
   {
           this.parmCallerName(element.args().caller().name());
   }
   else if(element.args().caller() && element.args().caller().name() == formStr(B))
   {
           formRunCaller = element.args().caller();
           this.parmCallerName(formRunCaller.parmCallerName());
   }
   

So now every time you use that parm method of FORM-B in this scenario, you can get the root caller form name.

Enjoy
