在按键触发时调整大小

Question

I have a classic Form1 class that inherits the Form class. The problem is I press the buttons and no events get fired.
Inside the Form1 there is a webBrowser which occupies the whole Form1.

Here is my code:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        WindowState = FormWindowState.Maximized;
        KeyPreview = true;
        PreviewKeyDown += wb_PreviewKeyDown; 
    }

     private void wb_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
    {
        Console.WriteLine("EDOOOOOOOOO");   
        if (e.Control && e.KeyCode == Keys.C)
        {
            // Do something funny!
        }
    }
}

The wb_PreviewKeyDown is not fired whatever button I push.

Answer 1

If you press a key on the form, the event will get fired.
However, if you have a TextBox or something on the form, and you press a key on that, the event will NOT fire, because now the TextBox has received the input.

This can easily be fixed by setting the property KeyPreview = true on the form.
You can set this in the designer, or in code (see the answer of @Isma)

EDIT: Since you have a WebBrowser control on your form, you need to do it somewhat different, see this Handling key events on WebBrowser control

It involves using the PreviewKeyDown event of the WebBrowser
