Bonjour à tous, j'ai un problème qui est énervant.

J'ai un combobox qui contient la liste des clients.

En sélectionnant un client, mon datagrid doit afficher la liste des commandes du client.

Le problème est : au moment du chargement de la feuille, le combo est positionné au 1er client mais mon datagrid n'affiche pas les commandes du 1er client...

Mon code est :

Code : Sélectionner tout - Visualiser dans une fenêtre à part

Comment faire pour lancer l'évenement du combo (SelectedIndexChanged) au moment du chargement de la feuille?

merci de conseiller sur la manière la plus propre...
