Hello, there is some misunderstanding with such a thing as an event. Just basically wrote only console applications. In general, the task is simple: by pressing the button in the panel , some drawing should appear. I need to somehow trigger some other drawing event in the button_click method. I tried to just directly write directly: button1.Click = new System.Windows.Forms.PaintEventHandler(this.panel1_Paint) , but the compiler swears at the PaintEventHandler delegate, requires EventHandler . Thank you in advance. And in general, I would be extremely grateful if someone told the site where there are a bunch of examples of working with various components and how to link them.

    The Paint event is fired when the control is redrawn.

    Create an event handler

     private void SomePaintEventHandler(object sender, PaintEventArgs args) { // В качестве примера args.Graphics.DrawString("Text", new Font ("Tahoma", 12), new SolidBrush (Color.Green), 200, 200); }

    We delegate the event

     this.Paint += new PaintEventHandler(this.SomePaintEventHandler);

    We initiate copying

     this.Invalidate();

    Read on: handling and call events .

      MSDN: PaintEventHandler - delegate .

      Windows applications - WinForms is a very good site for beginners, I hope you will find a lot of useful information for yourself.
