Beispiele

Das folgende Codebeispiel ruft für BindingManagerBase eine bestimmte Datenquelle ab und gibt Informationen zu jeder Control Eigenschaft aus, die an die Datenquelle gebunden ist. Im Beispiel wird die Bindings -Eigenschaft von BindingManagerBase verwendet, um alle Steuerelemente abzurufen.

void PrintBoundControls1()
{
   
   // Get the BindingManagerBase for the Customers table.
   BindingManagerBase^ myBindingBase = this->BindingContext[ ds,"Customers" ];
   
   /* Print the information of each control managed by
         the BindingManagerBase. */
   System::Collections::IEnumerator^ myEnum = myBindingBase->Bindings->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      Binding^ b = safe_cast<Binding^>(myEnum->Current);
      Console::WriteLine( b->Control );
   }
}

         is appended to the parent table's name. */
