Chart FX Guage Trial Edt Exception

Recommended Posts

 Just downloaded Chart FX Guage (Trial Edt) and dropped into a new project. When I run the program the following error is generated at runtime.  Doesn't matter which control I use the same behavior is produced. 

Environment: Visual Studio 2005

Language: C#

Any ideas??

 System.InvalidOperationException was unhandled

  Message="It has been detected that the gauge was modified outside its UI-thread. Marshalling the execution of your code onto the UI thread in the Windows Forms environment is critical to prevent cross-thread usage of UI code. Use InvokeRequired/Invoke for for synchronous marshalling. Use InvokeRequired/BeginInvoke for asynchronous marshalling."

Like all Windows Form Controls, Gauges is a single threaded control. The error is saying that you are invoking a method of the gauge from a thread that is different than the application's UI thread.

Please try the following:

1) Create a new Windows From application

2) Drop a Gauge

3) Run the app
