Cochez cette case si la valeur n'est pas supérieure à 1

Question

Comment empêcher l'utilisateur de cocher la case d'une ligne de grille si la "Qté" de cette ligne de grille est "0"? J'ai le code ci-dessous mais il le permet toujours car tant qu'il y a une ligne sélectionnée, elle permet de sélectionner la seconde et ainsi de suite sans changer la valeur de la Qté. La ligne sélectionnée de chaque bouton ci-dessus est ensuite envoyée à form2.

     columns.AddRange(dataColumn);

Vous pouvez utiliser l'événement CellBeginEdit qui se produit lorsque le mode d'édition démarre pour la cellule sélectionnée.

Private Sub YourDataGridView_CellBeginEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles YourDataGridView.CellBeginEdit 

    Try 
     With Me.YourDataGridView 
      If .Columns(e.ColumnIndex).Name = "YourCheckBoxColumnName" AndAlso .Rows(e.RowIndex).Cells("YourQuantityColumnName").Value > 1 Then 
       e.Cancel = True 
      End If 
     End With 
    Catch ex As Exception 
    End Try 

End Sub
