Im having some trouble adding a spreadsheet to my RadPageViewPage since the spreadsheet requires to be on a thread. This still gives me 'Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.'.
Is there anyone that could explain what im doing wrong here? Thanks.
Edit. Updated the code a bit and this gives me that it requires to be on the STA thread. Its something im not understanding with these threadings in c#.
var threadParameters = new ThreadStart(() => { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new ExpressTransportForm()); }); var thread2 = new Thread(threadParameters); thread2.SetApartmentState(ApartmentState.STA); thread2.Start();
