Ich bin mit VS 2013 C# und asp.net, einige Zeilen leer sind und diese Zeile Ich mag würdelöschen leere Zeile in Datentabelle C#
Siehe das Bild löschen Below
ich habe versucht, diesen Code aber funktionierte nicht, keine Ahnung,

Die erste Zeile sieht nicht leer aus ... Es gibt eine 1. in der ersten Spalte. – JohnG
