c# - Why KeyDown event wont fire? -


my original intention in make enter event text box run btnok_click event, after several try can't make happen, tried way , try keypress key still didn't work, made these 2 simple code, still didn't work either;

    private void textbox2_keydown(object sender, keyeventargs e)     {         if (e.keycode == keys.enter)         {             //enter key down             //btnok_click(this, e);             system.windows.forms.messagebox.show("my message here");         }     }     private void textbox2_keypress(object sender, keypresseventargs e)     {         if (e.keychar == (char)keys.return)         {             //enter key down             //btnok_click(this, e);             system.windows.forms.messagebox.show(((char)keys.return).tostring());         }     }

any suggestion? read similar questions , said set isinputkey property true can't find anywhere. use visual studio 2008

two options : 1) use key event as

public void txt_keyup(object sender, keyeventargs e)         {             if (e.keycode == keys.enter)             {                 btnok_click(sender, e); // or btn.performclick();                 return;                            }         }

2) make btnok acceptbutton of form. (note : textboxes in form)

this.acceptbutton = btnok;
