Question

I want to duplicate a control like a Button, TextBox, etc.
But I don’t know how I can copy event handler methods (like Click) to the new control.

I have the following code now:

var btn2 = new Button();  
btn2.Text = btn1.Text;
btn2.size = btn1.size;
// ...
btn2.Click ??? btn1.Click

Is there any other way to duplicate a control?

Answer 1

To clone all events of any WinForms control:

var eventsField = typeof(Component).GetField("events", BindingFlags.NonPublic | BindingFlags.Instance);
var eventHandlerList = eventsField.GetValue(button1);
eventsField.SetValue(button2, eventHandlerList);
