Question

I have about 15 text boxes and instead of going to the event handler on each one and enabling a button on a change..

For example:

    Private Sub txtIsbnUpc_TextChanged(ByVal sender As System.Object, _
                                       ByVal e As System.EventArgs) _
        Handles txtIsbnUpc.TextChanged

        cmdSearchresults.enabled = true
    End Sub

Instead of going through each one and typing that is there a simpler way?

Answer 1

Why don’t you extend the Handles list and handle all textBoxes events in one handler?

Private Sub txtIsbnUpc_TextChanged(ByVal sender As Object, ByVal e As EventArgs) _
    Handles txtIsbnUpc.TextChanged, txt2.TextChanaged, txt3.TextChanged

You can use sender to check which textBox fired that handler, if it’s needed for your logic.
