Ich erstelle einen dynamischen Link während page_init even und binding onclick auf einen Link button.On click von dynamic link ist in der Lage zurück zu posten, aber es wird kein onclick Event ausgelöst (trifft auf ein on click Event in Debug-Modus). Seitenpostback und zeigt eine leere Seite an, ohne ein Ereignis auszulösen. Bitte sagen Sie mir im folgenden Code, was ich falsch mache. Ich benutze vs2005 (ASp.Net 2.0). Bitte sehen Sie den ersten Schalter Fall, wo ich dynamisch eine Link-Schaltfläche erstellen.ASP.NET Dynamischer Link Button
