السلام عليكم

في الكود التالي من المفترض ان يتم تفعيل الأزرار المشار اليها في الكود ولكن مايحدث هو ان الازرار لا تتغير خاصيتها من false الى true

PHP كود :

Private Sub frmAddNew_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        If txtCRN.Text = "" And txtBarwahNo.Text = "" Then
            btnSaveAll.Enabled = False
        Else
            btnSaveAll.Enabled = True
        End If

        If txtCRN.Text = "" Then
            btnSaveInfo.Enabled = False
        Else
            btnSaveInfo.Enabled = True
        End If
    End Sub
