Parent Form Refresh using x++

//Add this Method in Parent Form

void Form_doRefresh()
{
;

NetBuildings_ds.reread(); // Parent Form and Child Form Datasource Name
NetBuildings_ds.executeQuery();
NetBuildings_ds.refresh();

NetUnitDetails_ds.reread();
NetUnitDetails_ds.executeQuery();
NetUnitDetails_ds.refresh();
}

//Add this Method in Child Form where you need to Refresh the Parent Form

public void close()

{

    if(formHasMethod(element.args().caller(), identifierStr(Form_doRefresh)))//Form_doRefresh is Parent Method                                                                                                          Name
   {
        element.args().caller().Form_doRefresh();
   }

   super();
}
.................................................................................................................................................................

void bookrefresh()
{
   

.reread();

   

.refresh();

}

In the child form, you can do this –

void bookRefresh()
{
   FormRun callerForm = element.args().caller();

   if (callerForm)
   {
      if (callerForm.name() == formstr(

))

     {
         callerForm.bookRefresh();
     }
   }
}
