How to create a Leave event for a Text Box

I need to create a leave event for a text box called txtZoneA

Once the user leaves the text box I will be required to validate the data in the text box.


Thanks

Very basic outline:

    Private Sub txtZoneA_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtZoneA.Leave
        If DataIsValid() Then
            'do whatever
        Else
            'Do what you need to let the user know the data is invalid
            txtZoneA.Focus()
        End If
    End Sub

Replace "DataIsValid()" with whatever logic is used to determine what data is valid.  The Focus call in the else clause doesn't let the user leave the TextBox unless the input is valid, take it out if this is not your desired behavior.
