Nu zou ik die `Request.QueryString["id"]` willen laten parsen, maar het is mij een beetje onduidelijk op welke manier.
Nu dacht ik ook om bijv. in de codebehind van die .aspx file het volgende te doen:

myItem.Text = "test";
phMenuBar.Controls.Add(myItem);
}

}
} |
Maar ik krijg niet de naam "test" als item erbij te zien, hij geeft geen foutmelding ofsow maar hij laat gewoon niet die "test" erbij zien.
Wie weet wat het probleem is en kan mij door deze code helpen wat het probleem precies is en wat ik moet doen om het op te lossen.
Alvast bedankt voor de reacties.
