Anzahl der benutzerdefinierten Dialogfelder (Datums- und Zeitauswahl) in Bezug auf Optionsfelder
Ich habe eine Gruppe von Optionsfeldern, wie in der Code-Schaltfläche unten gezeigt. Wenn ich auf ein Optionsfeld klicke, möchte ich ein anderes Dialogfeld, wie in der folgenden Abbildung gezeigt. Ein Dialogfeld für jedes Optionsfeld. Dies sollte sich in Dialogfeldern befinden. Wie mache ich das?Am Ende muss ich nur noch diese benutzerdefinierten Dialoge generieren. Kann mir jemand helfen, wie ich es schaffen kann?
Außerdem erhalte ich eine Nullzeigerausnahme. Wie löse ich das ??
