     } 
    } 

, wenn Benutzer auf dieser Seite klicken Sie auf die nächste Seite als

www.mypage erzeugt wird/Entersession.aspx? Session = session_id

aber ich würde eher, es haben wie

www.mypage/Entersession.aspx? session = session_name

beide Sitzungs_ID und session_name sind aus der Datenbank

keine Idee?

} 

Answer 1

Gerade

ändern

test.Controls.Add(GetButton(thisReader["session_id"].ToString(), "Join Session")); 

zu

test.Controls.Add(GetButton(thisReader["session_name"].ToString(), "Join Session")); 

Answer 2

Ist das wonach Sie suchen? Ändern CommandArgument zu benennen? Es ist eine sehr, sehr einfache Lösung.

aktualisieren

Sie könnten einen commandArgument Parameter GetButton() hinzuzufügen.

private Button GetButton(string id, string name, string commandArgument) 
    { 
     Button b = new Button(); 
     b.Text = name; 
     b.ID = "Button_" + id + i; 
     b.Command += new CommandEventHandler(Button_Click); 
     b.CommandArgument = commandArgument; // this changed to commandArgument 
     i++; 
     return b; 
    } 

    GetButton(thisReader["session_id"].ToString(), "Join Session", thisReader["session_name"].ToString()) 

Answer 3

Die Änderung, die Sie suchen findet in dem Sie verwenden Ihre GetButton Methode

Wechsel:

test.Controls.Add(GetButton(thisReader["session_id"].ToString(), "Join Session")); 

An:

test.Controls.Add(GetButton(thisReader["session_name"].ToString(), "Join Session")); 

Ihr erster Eingabeparameter GetButton wird die CommandArgument abgebildet wird. So wird es passieren, session_name in statt session_id zu passieren.
