ErrorProvider question...

I have a form with a bunch of textboxes. Each text box gets validated
with the ErrorProvider. I want the form to process something ONLY when
ALL the textboxes are valid.
I found a solution, but it seems like a workaround. I'm not sure if
it's the best way:

Dim ErrorCounter As Integer

Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnOK.Click
If TextBox1.Text = "" Then
ErrorProvider1.SetError(TextBox1, "Error")
ErrorCounter += 1
Else
ErrorProvider1.SetError(TextBox1, "")
End If

If TextBox2.Text = "" Then
ErrorProvider1.SetError(TextBox2, "Error2")
ErrorCounter += 1
Else
ErrorProvider1.SetError(TextBox2, "")
End If

If ErrorCounter = 0 Then
'process code that only happens when there are NO errors
End If
End Sub


Is this a good way to handle it, or am I missing a better technique?

Thanks!
John
