DataGridView contrôle de saisie (ex.: Numérique)Résolu

Question

Bonsoir,

Comment dans les cellules d'une colonne d'un DataGrdView n'autoriser que la saisie de chiffres ??
Ou comment récupérer l'évènement PressKey d'une cellule ?

Merci

 Private Sub CheckCell (ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
 
    Dim KeyAscii As Short = Asc(e.KeyChar)
    '... 
 
    '... code to check the input
 
    '... 
 
    If KeyAscii = 0 Then 
        e.Handled = True 
    End If
 
End Sub
 
' pass control to the keyPress-Event of active cell
Private Sub DataGridView_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView.EditingControlShowing
 
    Try
 
        '...to us this is a criteria, to only find and check "numeric" cells
        If e.CellStyle.Alignment = DataGridViewContentAlignment.MiddleRight Then
            AddHandler e.Control.KeyPress, AddressOf CheckCell 
 
        Else
 
            'in order to prevent "optical problems", we had to call the removeHandler twice
            RemoveHandler e.Control.KeyPress, AddressOf CheckCell
            RemoveHandler e.Control.KeyPress, AddressOf CheckCell 
 
        End If
 
    Catch ex As Exception
 
    End Try
 
End Sub
