Update UI state from an another Thread in Windows Forms

An exception is thrown when trying to update control state from an another Thread.

Thread newThread = new Thread(new ThreadDelegate(() => {
   txtStatus.Text = "Started";
}));

newThread.Start();

Solution

We use BeginInvoke to update UI state asynchronously.

Thread newThread = new Thread(new ThreadDelegate(() => {
   txtStatus.BeginInvoke(() =>
   {
       txtStatus.Text = "Started";
   });
}));

newThread.Start();

Happy coding!
