dd1.Items.Insert(0, new listitem("Any location", "%")) 

Et l'erreur CommandText n'a pas été initialisé continue d'afficher sur l'observateur d'événements IIS journal

Je ne peux pas reproduire le problème moi-même mais je sais il se produit peut-on suggérer quoi que ce soit

L'erreur indique qu'il se produit avec cette ligne dd1.DataSource = LogData.StermQ3(datelistquery).Tables(0).DefaultView

Merci

Answer 1

Je pense que vous êtes dans une situation où aucune des conditions suivantes sont remplies:

Session("TenHolStDateHP1") = "%" 
Session("TenHolStDateHP1") = "" 
Session("holidayduration") = "3/4" 
Session("holidayduration") = "14" 
Session("holidayduration") = "7" 

Puisque vous n'initialisez pas datelistquery à quoi que ce soit et vous vous retrouvez dans un else if il semble possible que vous n'attribuez pas de requête à cette chaîne et que vous pouvez passer une chaîne vide à votre fonction StermQ3.

Vous pouvez ajouter une instruction else à la fin de votre chaîne de déclarations if/else if en tant que fourre-tout. Ce que vous définissez datelistquery dans l'instruction else dépend de ce que vous faites.
