Hi Arun

For what type of object do you want to create this class? Form, Table or another class?

If is a class the example that I've posted may help you, but it is another type of object you have to use eventhandlers, obviously the function will execute after or before (I think that would be the "super()" function that you are searching), depending of the event,

How to declare the super() in extension class.

Is there another way to call super() in class extension in D 365.

For EX:

[FormDataSourceEventHandler(formDataSourceStr(LedgerJournalTransCustPaym, LedgerJournalTrans), FormDataSourceEventType::ValidatingWrite)]

public static void LedgerJournalTrans_OnValidatingWrite(FormDataSource sender, FormDataSourceEventArgs e)

{

Super()// super not allowed here...

}

Hi Arun

If you extend a class you can override the functions, for example when you develop reports you extend the SRSReportDataProviderBase when you create your DP Class and override processReport() method.

The next may help you.

Noticed that both functions must have the same sign (parameters)

Class Main()

{

public void mainfunction(VendAccount _account)

{

// Do something for main function

}

}

Class Child extends Main

{

public void mainfunction(VendAccount _account)

{

super();//execute the mainfunction for mainclass

// Do something for child function

}

}

I hope this is what you are searching.
