Hello,

J'en perds mon latin...

Voici un petit bout de code :

Code:

        If promo.DTO.DetailsDemo.Count > 0 OrElse promo.DTO.DetailsOwn.Count > 0 Then
            If MessageBox.Show(String.Format(messages.GetText("msgDeletePromo"), vbCrLf),
                               messages.GetText("msgQuestion"), MessageBoxButtons.YesNo, MessageBoxIcon.Question) = Windows.Forms.DialogResult.Yes Then
                promo.Delete()
            End If
        Else
            If MessageBox.Show(messages.GetText("msgDeleteLine"), messages.GetText("msgQuestion"), MessageBoxButtons.YesNo, MessageBoxIcon.Question) = Windows.Forms.DialogResult.Yes Then
                promo.Delete()
            End If
        End If

C'est un bout de code d'une application pour gérer les promotions d'un magasin...

Quelques explications :
Ligne 1 : On vérifie si des choses ont déjà été encodé pour la promo
Ligne 2 et 3 : On affiche une demande de confirmation pour la suppression en signalant que ce qui a déjà été encodé sera perdu (les messages.GetText("clef") vont chercher le texte à afficher dans la bonne langue)
Ligne 4 : On supprime
Ligne 7 : On affiche une demande standard de confirmation pour la suppression (rien n'est encore encodé donc pas besoin d'avertissement particulier)
Ligne 8 : On supprime

Le truc bizarre, c'est que lorsqu'on arrive sur les lignes 4 ou 8, le contenu de l'objet promo change pour devenir la première promo affichée dans la grille... Il y a bien un event RowEnter sur la grille (datagridview) mais je fais pareil dans toutes mes applications et c'est la première fois que j'ai un comportement pareil... (ou alors j'ai le bug partout et personne ne m'a jamais rien dit :aie:)

Pour info, le code de l'event RowEnter :

Code:

1
2
3
4
5
6
7
8
9
    Private Sub dgvPromo_RowEnter(sender As Object, e As DataGridViewCellEventArgs) Handles dgvPromo.RowEnter
        If e.RowIndex > -1 Then
            promo = promos.GetById(CInt(dgvPromo.Rows(e.RowIndex).Cells("dgvcId").Value))
        Else
            promo = Nothing
        End If
 
        EnablingMenuItem((Not IsNothing(promo)))
    End Sub

Rien de compliqué donc. Que du standard/basic...

Mais de toute façon, en debug step by step, on ne passe pas dans l'event. Donc aucune raison que le contenu de promo change...
J'ai fait une recherche sur le texte "promo = " histoire de trouver tous les endroits où j'affecte quelque chose dans mon objet et c'est le seul endroit...

Quelqu'un aurait une idée de ce qu'il se passe ? Dois-je faire venir un exorciste ? :aie:

N.B. : Si nécessaire, je peux montrer plus de code.

N.B.2 : Histoire de, voici le code des classes Promo et Promos...

[EDIT 1]
En mettant un point d'arret dans l'event RowEnter du dgv, le debugger passe bien dans l'event et e.RowIndex vaut 0. Ce qui explique le changement de contenu.

Par contre, ça n'explique pas pourquoi il passe dans cet event...

Enfin j'imagine que ça doit être car l'utilisateur répond au MessageBox.Show, donc il disparaît, donc faut repeindre les contrôles, donc la grille est "réinitialisée"...

C'est quand même bizarre... Pourquoi dans cette application et pas dans les autres...

[EDIT 2]
J'ai trouvé la cause du problème...

J'ignore totalement pourquoi mais il y a du code dans l'event Form.Activated et ce code fait appel à la fonction qui charge les promos depuis la DB et recharge la grille. Du coup, le RowEnter de la grille s'enclenche et c'est la 1e promo qui est prise...

Quelqu'un aurait une idée de pourquoi j'aurais été utilisé cet event Form.Activated alors que ça ne sert en fait à rien ? :aie:
