Ich arbeite derzeit mit einer Webseite mit Tabs. Der Zweck, den ich in diesen Code implementiere, besteht darin, zu verhindern, dass der Tab, den ich gerade aktiviere, zum ersten Tab zurückspringt, wenn ich irgendeine Taste drücke. Ich habe 2 Bild-Schaltfläche in jedem der Registerkarte, die hinzufügen und speichern ist. Nach dem Implementieren des Aktualisierungsfensters funktioniert die Schaltfläche "Hinzufügen" so, dass eine neue Zeile zur Rasteransicht hinzugefügt werden kann und auf der gleichen Registerkarte verbleibt, aber die Schaltfläche zum Speichern funktioniert nicht und hat nach dem Klicken keine Auswirkungen. Ich bin derzeit neu in ASP.NET C#. Ich möchte Hilfe von StackOverFlow erhalten, damit ich den Code durchschauen und auf meinen Fehler hinweisen kann. Danke an alle.ImageButton funktioniert nicht auf der Registerkarte Update-Panel

Hallo. @ Asif.Ali Danke für deine Antwort. Nach dem Entfernen 'UpdateMode =" Conditional "', wenn ich auf die Schaltfläche "Hinzufügen" drücke, wird Inhalt von anderen Registerkarten mit Inhalten aus der aktuellen Registerkarte angezeigt, und die Schaltfläche zum Speichern funktioniert immer noch nicht. Ich habe auch versucht den Trigger-Modus mit '
Versuchen Sie also, die Speicherschaltfläche manuell zu aktivieren. – AsifAli72090
Hallo. @ Asif.Ali Danke für deine Antwort. Ist der Auslöser manuell der selbe wie ich bei meinem vorherigen Kommentar erwähnt habe? Wenn es das gleiche ist, funktioniert es nicht. –
