private Button GetButton(string id, string name)

b.CommandArgument = id;
i++;

tb.ID = id;
return tb;
}
protected void Button_Click(object sender, CommandEventArgs e)
{
Response.Redirect("EnterSession.aspx?session=" + e.CommandArgument.ToString());
}
}
when users click from this page the next page is generated as
www.mypage/Entersession.aspx?session=session_id
but i'd rather to have it like
www.mypage/Entersession.aspx?session=session_name
both session_id and session_name are from the database
any idea?
}

Answer 1

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

Answer 2

The change you're looking for takes place in where you use your GetButton method
Change:
test.Controls.Add(GetButton(thisReader["session_id"].ToString(), "Join Session"));
To:
test.Controls.Add(GetButton(thisReader["session_name"].ToString(), "Join Session"));
Your first input parameter to GetButton is being mapped to the CommandArgument. So passing session_name in rather than session_id will do the trick.

Answer 3

Is this what you are looking for? Changing CommandArgument to name? It's a very, very easy fix.
Update
You could add a commandArgument parameter to GetButton().
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())
