Purpose:
Demonstrate how to get caller form name in a Form extension class in X++.
Application:
Dynamics 365 for Finance and Operations
Solution:
The code below gives a very good example of how can get the caller form name in a Form extension class in X++ which then can be used to run the business logic.
In the code below, we’re adding a display method for a control on the form RetailAddItems to display Site. We’re getting Site from a form data source on the caller form. In this case, caller form is PurchTable and caller form data source is also PurchTable.
Code
[ExtensionOf(formStr(RetailAddItems))]internal final class MAK_RetailAddItems_Extension{ display InventSiteId displayPurchSiteId() { InventSiteId siteId; FormRun callerFormRun; callerFormRun = this.args().caller(); if (callerFormRun.name() == formStr(PurchTable)) { FormDataSource purchTable_ds = callerFormRun.dataSource(formDataSourceStr(PurchTable, PurchTable)) as FormDataSource; PurchTable purchTable = purchTable_ds.cursor() as PurchTable; if (purchTable) { siteId = purchTable.InventSiteId; } } return siteId; }}
