First, thank you for evaluating r.a.d.controls for WinForms. I'm sorry for misleading you but it looks like there's an error in the documentation. The WaintingBar property which you should set is WaitingSpeed
. For the final release we added one more property - WaitingStep
which will be available for the official release next week.
The problem with the WatingBar control used in you particular application is that we start the waiting behavior of the control (as you have done via the StartWaiting() method) in the current thread of the application. We use timer ticks to change the position of the waiting indicator but we currently use the standard System.Windows.Forms.Timer class using its tick event, so when you try to establish a telnet session your application gets frozen for a few seconds and the timer starts ticking after the session is established. Then you call the EndWaiting() method of the control so there is no progress shown on the waiting area of the control.
Of course there's a workaround for this and we have attached a sample project (you have to update the references) which simply starts the telnet connection in a new thread and this way the UI of your application won't freeze while trying to connect to the telnet server.
I hope this information helps.
