GridView imbriqué OnRowCommand imbriqué

Question

J'ai essayé toutes les suggestions que j'ai trouvées ici et ailleurs. J'ai défini EnableViewState sur true et false pour la page. J'ai défini EnableViewState sur true et false pour les grilles. J'ai essayé d'enregistrer les événements pour la grille enfant dans la grille parente RowCreated. Je suis vraiment à une perte. Comment puis-je faire ce travail? Ni l'événement parent ou enfant ne déclenche.

Answer 2

Il y a plusieurs problèmes qui causent des problèmes.

Le bouton Ajouter a un événement onClick, mais vous utilisez également onRowCommand dans chaque grille. Lorsque vous cliquez sur le bouton Ajouter, trois événements sont déclenchés (clic sur le bouton, commande de ligne de la grille parente, commande de ligne de la grille imbriquée).

Il semble que vous utilisiez une variable globale VariantID. Cela fonctionne pour le CommandArgument, mais si vous l'utilisez dans le code HTML d'une page, il contiendra toujours uniquement la valeur d'ID de la dernière ligne ajoutée. Donc ça marche mais ce n'est pas recommandé. Mieux vaut utiliser quelque chose comme ceci CommandArgument='<%# Bind("itemID") %>'

Vous utilisez le VariantID dans l'attribut CommandArgument erroné dans le bouton Ajouter. vous utilisez CommandArgument="<%=VariantID%>" donc l'argument de commande est la chaîne <%=VariantID%>. Vous l'utilisez comme ceci CommandArgument='<%# VariantID %>'

Vous liez la grille en dehors du bloc try-catch sur OnLoad(EventArgs e). En cas d'erreur, la page complète de DotNetNuke est écrasée au lieu de déclencher le ModuleLoadException. Bien que cela pourrait être à des fins de test.

Réparer ces problèmes d'abord et voir si cela aide. Cela a été fait sur mon serveur de développement.
