I want to create a binding like this
public bool canManualSend
return port.IsOpen && send.Checked;
txtSending.DataBindings.Add(("Enabled", this, "canManualSend") ;<br/>
But it only works one time. After the form is loaded, whatever port.IsOpen or send.Checked is changing, the txt.Sending has no effect.
And how to make it work?
