Automatically Trim Spaces for DataBound TextBoxes

What I'd like to do is automatically trim spaces (or "space characters") from all text boxes just before the data is sent to the database.

I can do that with a global TextChanged even handler, but I'd rather do it just once instead of every time the "text changes".

Is there any event I can catch that might give me an opprotunity to trim() all the strings before they go into the DB/DataSet?

Thanks!

Hi mitchvincent;

You can use the Validating event handler to make the change once. It fires just before losing focus.

    Private Sub TextBox_Validating(ByVal sender As Object, _
        ByVal e As System.ComponentModel.CancelEventArgs) Handles _
        TextBox1.Validating, TextBox2.Validating

        Dim tb As TextBox = CType(sender, TextBox)
        tb.Text = tb.Text.Trim()

    End Sub
