Update UI state from an another Thread in Windows Forms

#dotnet #csharp #desktop #windowsforms

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();
Enter fullscreen mode Exit fullscreen mode

Solution

We use BeginInvoke to update UI state asynchronously.

Thread newThread = new Thread(new ThreadDelegate(() => { txtStatus.BeginInvoke(() => { txtStatus.Text = "Started"; }); })); newThread.Start();
Enter fullscreen mode Exit fullscreen mode

Happy coding!
