Invalid operation in multiple threads?

Question

Programming

I can't figure out what the code is asking me to do. Wrote an event handler for a button click. When the button is pressed, everything works. As soon as I transferred this code to the event of receiving data from the COM port, it swears at it ->

An "System.InvalidOperationException" exception occurred in System.Windows.Forms.dll ("Invalid multi-threaded operation: Attempted to access control 'dataGridView1' from a thread other than the thread it was created on.")

Answer 1

You cannot work with graphic elements from another thread. Use Invoke.
