HI i am trying to use the waitingbar bar but i can't get it to work, here is my code:

  private void btnCheckServers_Click(object sender, EventArgs e)  

        {    

                this.radWaitingBar1.StartWaiting();  

                label1.Text = "trying to connect....";  

                Telnet Session = new Telnet(this.txtIP.Text, Convert.ToInt16(this.txtPortTest.Text), 1000);  

                try 

                {  

                    Session.Connect();  

                    label1.Text = Session.ReturnMessage;  

                }  

                catch (Exception ex)  

                {  

                    label1.Text = ex.Message;  

                }  

                this.radWaitingBar1.EndWaiting();  

        }

Can someone tell me what i do wrong?

Thanx and greetings,
Wim

In the Help i read this:

Place a RadWaitingBar control and a RadButton control on a form.
Select the RadWaitingBar control.
Set the StepWidth property to 4.
Set the ThemeName property to ControlDefault.
Set the BackColor property to BlueViolet.
Select the RadButton control.
Set the Text property to Animate.
In the Properties window, click the events button.
Double-click the Click event.
Replace the automatically-generated event handler with this code:

thing is that i cant find property StepWidth!

Hello Wim,
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.

Telnet.dll is probably from a 3rd party library unrelated to Telerik. So you don't have to go searching for that, here is some example code that uses a separate thread in a similar way as the example application.

    
                    public void DoStuffThread() 
        
                    { 
        
                        // Pretend to do stuff that takes a long time 
        
                        Thread.Sleep(5000); 
        
                        DoneDoingStuff(); 
        
                    } 
        
                    private void radButton2_Click(object sender, EventArgs e) 
        
                    { 
        
                        radWaitingBar1.StartWaiting(); 
        
                        Thread thread = new Thread(new ThreadStart(this.DoStuffThread)); 
        
                        thread.Start(); 
        
                    } 
        
                    void DoneDoingStuff() 
        
                    { 
        
                        radWaitingBar1.EndWaiting(); 
        
                    }
