Add the following code in the class declaration
DialogField dlgType;
DialogField dlgAccount;
DialogField dlgName;
#DEFINE.dialogTypeFieldNo(800)
#DEFINE.dialogTypeCtrlName("Fld800_1")
#DEFINE.dialogAccountFieldNo(900)
#DEFINE.dialogAccountCtrlName("Fld900_1")
To allow the dialog to raise dialog field events
Override the dialogPostRun method and add the following code below the super()
dialog.dialogForm().formRun().controlMethodOverload(true);
dialog.dialogForm().formRun().controlMethodOverloadObject(this);
To add the controls to dialog
dlgType = new DialogField(dialog, typeid(SalesPurch),#dialogTypeFieldNo);
dlgType.init(dialog);
dlgType.label("Account Type");
// assert if resulting field name was not set as expected as this must match the method which processes the event, e.g. fld800_1_validate
Debug::assert(dlgType.fieldname() == #dialogTypeCtrlName);
dlgAccount = new DialogField(dialog,typeid(CustAccount),#dialogAccountFieldNo);
dialog.addCtrlDialogField(dlgAccount.name());
dlgAccount.init(dialog);
dlgAccount.label("Account");
dlgAccount.value();
// assert if resulting field name was not set as expected as this must match the method which processes the event, e.g. fld900_1_validate
Debug::assert(dlgAccount.fieldname() == #dialogAccountCtrlName);
dlgName = dialog.addField(typeId(Name));
dlgName.allowEdit(false);
Create a new method to handle the modified event of the account type field.
/// <summary>

{
dlgAccount.value('');
dlgName.value('');
}
return valueWasModified;
}

Create a new method to handle the modified event of account field.
