Hi Curtis,

If you want to trigger Qactions all you have to do is set parameter to 1 like so:
ele[0].SetParameter(20100, 1); // Trigger Button

or the event trigger that when a ui button is pressed to do a certain action would be so:

dialog.NextButton.Pressed += (sender, e) => Button_Pressed(sender, e, dialog);

public void Button_Pressed(object sender, EventArgs e, HelloWorldDialog dialog)
{
//Some Actions
}

Hope this helps.
