Ich habe eine Methode, die Tabelle erstellt und anschließend einen Repeater erstellt. Die Tabelle wird gerendert, der Repeater wird jedoch nicht gerendert. Die folgende Methode erstellt einfach zuerst eine Tabelle, füllt sie mit Informationen und erstellt dann dynamisch einen Repeater, der einwandfrei funktioniert. Der Repeater wird dann jedoch nicht auf der ASPX-Seite gerendert. Ich habe versucht, den Stringbuilder als String zurückzugeben, aber es funktioniert immer noch nicht. Hier ist der Code unten. Vielen Dank
