Masked Edit question

[ddrees]

I created a windows form that has a number of controls on it (mostly textboxes and checkboxes) that are bound to a dataset. I inserted a masked edit box to bind to a phone number field. Once I added that control with the data binding, suddenly, no data appears at all on any control (they are all blank). I remove the binding, and I can see data in the controls again.

So, to test things, I bound a standard textbox to the phone number field, and created a button that, when clicked, would set the text property of the masked edit box to the text property of the phone number text box. When I click, nothing seems to happen. I added a line of code in the button click event to display in a messagebox the text property of the masked edit box after it had been set to the text property of the textbox. The message box displays the phone number!

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        maskPhone.Text = txtPhone.Text
        MessageBox.Show(maskPhone.Text)
    End Sub

So, the data is being assigned to the masked edit control's text property, but it isn't being displayed on the form at all. I even set the form to refresh afterward, but the masked edit still only displays the mask. Here are the settings on the masked edit control:
Mask: (###) ###-####
Format: (###) ###-####
Everything else is default settings.

Any ideas out there?
