Comment mettre à jour gridview lorsque vous cliquez sur le bouton Soumettre?

Question

Je veux ajouter le détail du stand dans la base de données, après l'utilisateur, insérer le pseudonyme du stand, sélectionner le type de stand et la durée du stand, cliquer sur le bouton soumettre et le nouvel enregistrement apparaît dans la grille sous les anciens enregistrements.

Je sais qu'il ya quelque chose qui manque dans le code mais je ne sais pas quel est le problème.

Answer 1

Je vois dans votre méthode de ButtonAddNewBooth_Click vous manque le ExecuteSql() pour le code bind sqlcommand et gridview

Après l'ajout de paramètres t o cmd ajouter les deux lignes suivantes un pour exécuter l'insert et l'autre pour reconsolidation la grille

cmd.ExecuteSql() 

GridViewBoothAdded.DataBind() 

Answer 2

Pouvez-vous vous déplacer GridView code de liaison de données à code-behind fichier Page_Load Méthode & appel le même code à la fin de votre événement ButtonAddNewBooth_Click. Cela servira votre but.
