How to call a method from a caller form

Introduction: Lots of time we need a method from calling object to be run when the code is running from called object for example if we have a class called by a form object and we need some values in class from a caller form object then we can get those values by calling a method from a caller from in a class.

Let’s see a real life example in dynamics which shows how we can do this.

• Open “ProjInvoiceProposal” form in AOT and then you will see a button as “Create invoice” in the right side.
• Actually this MenuItemButton is calling “ProjInvoiceChoose” class.
• Let’s go to class node and search “ProjInvoiceChoose” class, once you get the class just right click and select edit option this will open all its methods.
• Go to “Main” method of the class and you will see some code similar to given below.

if (args && args.caller())

{

projInvoiceProjId = args.caller().projInvoiceProjId();

projId = args.caller().projId();

}

if (args.caller() && args.caller().callerDataRecord())

{

argsTrans.record(args.caller().callerDataRecord());

transIdList = ProjInvoiceChoose::createTransIdList(argsTrans);

}

• Here you can see the statement like “args.caller().projInvoiceProjId();” In this args.caller() refer to the calling object that is “ProjInvoiceProposal” form in this case and "projInvoiceProjId()" is a method which is created in caller form and called in “ProjInvoiceChoose” class.
• Similarly two more methods called by args.caller() that is “projId()” and “callerDataRecord()”.

Note: You can check the “ProjInvoiceProposal” form and in the method node of the form you will find these methods.

Summery: So this is how we can easily call methods from calling object and use it as per our requirement.
