Hi all, i have a little question:

Why this code is not firing _ValidateEdit event?

Code:
Private Sub btnmarcamanual_Click()
Dim X As Long

With Gr1

For X = 1 To .rows - 1
    If .TextMatrix(X, .ColIndex("blanco")) = "X" Then
        .StartEdit X, .ColIndex("fechaenvio")
        .TextMatrix(X, .ColIndex("fechaenvio")) = Date
        .CommitEdit
    End If
Next X

End With
End Sub
